Abstract

International audience, In this paper, an innovative 4G antenna solution operating in the 698-960 MHz band, is presented. It is composed of two radiating elements recombined in a single feed antenna-system using an integrated power divider/combiner, synthesized thanks to five lumped components. Simulations using realistic SMD (Surface Mount Devices) components allow reaching a matching better than -6 dB, confirmed by measurement and an average total efficiency of 30% over the full frequency band. These results are benchmarked with the performance of measured commercial handset antennas, demonstrating a key improvement of the achievable bandwidth and total efficiency. Proposed solution seems promising in order to address 4G wideband antenna design challenges.

Abstract

International audience, An innovative LDS 4G antenna solution operating in the 698-960 MHz band is presented. It is composed of two radiating elements recombined in a single feed broadband antenna system using a diplexer. This circuit is realized thanks to lumped components, assembled directly on the plastic piece which supports the antenna. Corresponding measurements show a 260 MHz wide bandwidth (for S11@-6dB) and close results when diplexer integration is made onto FR4 PCB. It validates the plastronics integration scheme for innovative antenna module solutions.

Abstract

Conférence virtuelle; International audience; A new pattern reconfigurable 2×2 array antenna is proposed. The antenna has two modes of operation, Array Mode and Multiple-Input-Multiple-Output (MIMO) Mode. The single element antenna used is a pattern reconfigurable U-slot antenna with four pattern configurations. An average efficiency of 80%, a peak gain of 9.4 dB, and an overlapped −10 dB impedance bandwidth of 200 MHz around the resonant frequency 3.65 GHzare achieved. The size of the proposed antenna is 140×140×21 mm3 , which is suitable for small cell base-stations. For the MIMO Mode, the antenna has a maximum ECC of 0.06 between the four patterns and a minimum isolation of 12.9 dB between the four ports. For the array Mode, the antenna has a peak gain of 12.5 dB, and steering angles for 0 ◦ ≤ θ ≤ 30◦ in the planes at φ = 0◦ and φ = 90◦ Pattern reconfigurability is achieved using electrical switching. The used substrate is FR-4 with a dielectric constant of Epsilon_r = 4.4, and a loss tangent of tan δ = 0.02.

Abstract

Conférence virtuelle; International audience; In this paper, a miniaturized omnidirectional circularly polarized (OCP) antenna for Internet-of-Things (IoT) applications is presented. The CP waveform is synthesized by combining two linearly polarized antenna elements which act as electric and magnetic dipole, respectively. The vertical and the horizontally polarized elements are integrated and fed by a single port. The OCP antenna achieves a CP bandwidth covering 80 MHz from 2.4 to 2.48 GHz. The results show that the antenna can provide at 2.44 GHz an axial ratio lower than 3 dB and gain variations of less than 1.1 dB over all azimuth angles. The OCP antenna is printed on two cost-effective FR-4 PCBs and it is very low profile. Thanks to its radiation and geometric properties, the proposed antenna solution fits well in specific IoT use cases where a monopole-type radiation pattern is required.

Abstract

International audience; Our objective in this work is to design a printed antenna that has at once a low profile, a wide bandwidth, and a high gain. In order to achieve this objective, we have based our study on the theory of Electromagnetic Band Gap (EBG) structures where the EBG structure is used as the ground plane of the antenna. The first part of this article describes the geometry and the performances of the printed antenna originally designed on classic ground plane. In the second part, we illustrate the results obtained for this antenna designed on ground plane based on EBG Mushroom-like structure. In the third part, we will give the results obtained for the antenna designed on ground plane based on a new EBG structure that has been proposed to fill the disadvantages of the EBG Mushroom-like structure. Finally, the last session draws a comparison between the results obtained, where the improvements brought by the novel EBG structure are illustrated

Abstract

International audience; During recent years, various research teams have developed 60-GHz chipset solutions, using both BiCMOS and advanced CMOS technologies. However, for the 60-GHz market to flourish, not only low-cost RFICs are required, but also cheap antennas and package solutions. In order to address these two last issues, we present the design of a Tx-Rx antenna-module using industrial high-temperature co-fired ceramics (HTCC) substrate for millimeter-wave (MMW) large-volume consumer applications. The antennas are integrated within the module. Measured realized peak gain is above 6 dBi over the 57-66-GHz frequency band.

Abstract

International audience; We describe the design, fabrication and measurements of an axisymmetric dielectric lens, featuring a sectorial radiation pattern at 77 GHz. It will be used as the primary feed of a lens-based compact antenna test range (CATR). Due to symmetry of revolution, the sectorial lens profile can be designed in one dimension by using phase only control. The phase variation is echoed on the lens depth. The resulting stepped lens is simulated using France Telecom Orange Labs SRSRD software (¿in-house¿ software developed for dielectric axisymmetric radiating structures) and measured in an anechoic chamber at 77 GHz. Two lenses were fabricated with different materials: PVC and polyurethane, respectively. Good agreements were obtained between simulations and measurements. Less than 0.2 dB ripple in the central beam are obtained for the polyurethane lens although relatively high secondary lobes occur at 11°. Comparisons between the near field of a CATR illuminated by a small horn providing a uniform amplitude taper and the sectorial lens are conducted using numerical simulations. Results show that on-axis oscillations are reduced from 6 to 1 dB with the sectorial lens.

The forward problem is solved using an integral formulation of the EM problem with finite element discretization. The topological shape gradient is computed based on a topological deformation and fast linear system transformation algorithm. Different configurations of antenna arrays are studied for investigating the performance of the inverse algorithm and optimization procedure.

Abstract

In this letter, the design and measurement results of a millimeter-wave beam switching antenna are presented. Several antenna prototypes have been fabricated and measured in planar and conformal installations. The developed prototype consists of three antenna arrays of 16 patch elements in each array and it is operating at 61 GHz with linear polarization. A single-pole three-throw semiconductor switch is attached to the manufactured prototype using copper pillar attachment. The main beam direction of the convex antenna can be changed by switching between the antenna arrays in the prototype. Half sphere 3-D radiation pattern measurements have been performed. For the convex prototype, bent on the cylinder with radius 25 mm, beam switching with ${-{\hbox {32}}^\circ / + {\hbox {34}}^\circ} $ degrees is achieved.

Abstract

We present the design and characterization of a triband low-profile antenna based on the use of artificial magnetic conductor (AMC) surfaces. The engineered double AMC substrate allows reducing the separation between the radiating element and the ground plane. The radiating element is a wide band microstrip elliptical dipole and is associated to the double AMC substrate to cover the (790–860 MHz) GSM, the (1710–1880 MHz) DCS and the (1920–2170 MHz) UMTS telecommunication frequency bands. The whole antenna system presents a reduced level of backward radiation and is intended to be inserted in the back of a jacket. Presented experimental performances agree qualitatively with the numerical ones. The fabricated prototype demonstrates the feasibility of a triband antenna with a substantial reduction of the thickness through the use of AMC surfaces. © 2015 Wiley Periodicals, Inc.

Abstract

In this paper, we study the influence of the radius of a cylindrical supporting structure on radiation properties of a conformal millimeter-wave antenna array. Bent antenna array structures on cylindrical surfaces may have important applications in future mobile devices. Small radii may be needed if the antenna is printed on the edges of mobile devices and in items which human beings are wearing, such as wrist watches, bracelets and rings. The antenna under study consists of four linear series-fed arrays of four patch elements and is operating at 58.8 GHz with linear polarization. The antenna array is fabricated on polytetrafluoroethylene substrate with thickness of 0.127 mm due to its good plasticity properties and low losses. Results for both planar and conformal antenna arrays show rather good agreement between simulation and measurements. The results show that conformal antenna structures allow achieving large angular coverage and may allow beam-steering implementations if switches are used to select between different arrays around a cylindrical supporting structure., Comment: Keywords: conformal antenna, millimeter-wave communications, patch antenna array. 11 pages, 10 figures, 1 table

Abstract

International audience; The integration of a Vivaldi antenna on a printed circuit board (PCB) targeting 60-GHz WiGig applications is presented in this letter. The integrated passive device (IPD)technology from STMicroelectronics based on a glass substrate is used for the antenna manufacturing. In free space, the radiation pattern measurements show a realized gain higher than 4 dBi in the endfire direction from 56 to 65 GHz. The impact of the integration of the antenna on the PCB is investigated in details showing reasonable disturbance of the reflection coefficient, but strong modifications of the radiation pattern, especially the pointing direction of the main beam. From the analysis of the surface waves propagating along the PCB when the Vivaldi is integrated, a novel topology is proposed to preserve the main radiation in the endfire direction with enhanced realized gain.

Abstract

International audience; In this paper, two antenna designs using active components are presented for reflection coefficient tunability. The antennas are designed within the scope of the Artemos project and use MEMS switches and BST tunable capacitors internally available in the project. The first antenna uses an SPDT MEMS switch to select between one of the two target frequency bands (700-960MHz and 1.7-2.7GHz). The second antenna uses a tunable capacitor with a tuning range of 2.5-4pF, to frequency tune the reflection coefficient between 700 and 960MHz., The coverage of the 1.7-2.7GHz band is achieved by a monopole antenna who is fed separately.

Abstract

International audience; A novel approach for antenna designs covering the LTE frequency bands in a mobile handheld terminal is proposed. The concept consists of a low-band antenna operating in the 700-960MHz band, associated with a high-band antenna operating from 1700 to 2700MHz. The two antennas are separately fed and exhibit high port-to-port isolation. The low-band antenna is of “coupling element” type, modified to be hollowed. The space made available inside this hollow coupling element is then used to insert another antenna operating in the higher frequency bands. The port-to-port isolation between the two antenna feeds is increased using both some antenna placement techniques and bandstop behaviors of matching networks in the frequency bands of interest. Two antenna prototypes are designed, manufactured and measured to validate the simulation results. The effect of the user is also investigated via S-parameter and total efficiency measurements.

Abstract

International audience; Two antenna designs, using MEMS switches for operating band reconfigurability are presented in this paper. The study has been carried out in the scope of ARTEMOS project, whose main target is to propose tunable architectures for future mobile terminals. For this purpose, two antenna designs to cover 700-960MHz and 1.7-2.7GHz are proposed., The switching between low-band (700-960MHz) and high-band (1.7-2.7GHz) is achieved by using MEMS switches. The first design consists of a driven monopole which is capacitively coupled to a parasitic strip, whose input impedance is changed by using a two-branch matching network and the branch selection is done using MEMS switches. The second design uses two driven strips, one of which is capacitively coupled to a parasitic strip. By choosing between the driven strips with the MEMS, the parasitic strip enabling the low-band coverage is excited (or not). In this way, operating band tunability is achieved between low-band and high-band.

Abstract

An antenna-system covering the LTE700 and GSM850/900 standards is presented. The proposed structure has been designed to fit in generic handheld devices. It has been manufactured using Laser Direct Structuring technology on a plastic piece. The principal design challenge for the antenna is to cover the target band with a short ground plane (75mm). To be able to cover from low LTE (700-787MHz) up to GSM850/900 (824-960MHz) frequencies with this short ground plane, coupling element antennas are optimized in conjunction with matching networks. In this way, one of the antenna ports covers the low LTE standard, while the other port covers the GSM850/900 frequencies. To obtain an acceptable level of isolation between the antenna feeds, the neutralization technique is used. The proposed antenna was manufactured and the reflection coefficient and total efficiency measurements were performed, showing very promising and competitive performance.

Abstract

In this paper, we present the results of a method for optimizing multi-antenna systems from imposed constraints (e.g. ideal radiation patterns at a single frequency or over a wide frequency range). The method is based on a surface integral formulation of the forward EM problem and a gradient method for minimizing a cost functional. The originality of the method lies in the analytic calculation of derivative of the cost functional versus different parameters such as location and shape. Various configurations of systems involving planar antennas illuminated by dipoles are studied. The robustness of the algorithm is investigated with noise-corrupted data.

Abstract

An antenna to cover the LTE700 and GSM850/900 frequency bands (i.e. 700-960MHz) for a typical handheld mobile communication device is presented. The design challenge is the relatively short system ground plane which is only 75mm long, relying only on the smartphone touchscreen as the ground plane. In order to obtain a high bandwidth potential with a single antenna feed, a grounded parasitic element is used in conjunction with the main excited strip. The antenna is manufactured using Laser Direct Structuring technology on a plastic piece. The connection between the antenna on plastic and the PCB is done thanks to two pogo-pins placed underneath the plastic piece. To tune the antenna to the desired frequency bands, a matching network consisting of only two lumped elements was manufactured on the PCB at the antenna feed. The target frequency band (i.e 700-960MHz) is covered with a reflection coefficient below -6dB both in simulations and measurements. The total efficiency of the antenna is measured to be higher than 45% on the whole bandwidth.

Abstract

International audience; In this communication, a fully automatic measurement setup for the voltage distribution of a rectenna in space is reported. This 3D voltage pattern defines the variation of the DC voltage obtained by a rectenna as a function of the direction away from the transmitting antenna. It allows optimizing the placement of the rectenna in the zone of interest. A comparison is performed between the 3D voltage pattern of a 2.45 GHz rectenna and the radiation pattern of the receiving antenna. The results demonstrate that the influence of the rectifier on the radiating part cannot be ignored and validate the need of a 3D voltage distribution measurement to accurately characterize a rectenna system.

Abstract

In this paper, a low power and low cost ultra wideband impulse radio transmitter is presented. The transmitter includes a pulse generator integrated in a 0.13- $\mu{\rm m}$ standard CMOS technology and an antenna printed on the chip carrier. The board is manufactured with Roger 4003 laminate substrate and has a total area of 50 mm $\times\,$ 18 mm. The transmitter provides 1.4 V peak to peak Federal Communications Commission compliant pulses at antenna input for data rates up to 36 Mb/s in an on–off keying modulation scheme. The transmitter's power consumption is 12 mW at 1.2-GHz pulse repetition frequency and the energy consumption is 10 pJ per pulse. A 365-mV peak voltage emitted pulse is measured in an anechoic room at 0.8 m range with a receiver, including a horn antenna (8.3 dBi), a LNA (32 dB), and a 12-GHz real time oscilloscope.

Abstract

Best non-student Paper prize - 1st place; International audience; In this paper, we present a high efficiency antenna for 60 GHz low-cost packaged modules. This antenna is fabricated using IPD™ technology which is flip-chipped on a PCB Taclamplus substrate. A microstrip line etched on this Taclamplus substrate from Taconic is directly coupled to the upper patch antenna fabricated in the IPD™ technology from ST Microelectronics. A -10dB bandwidth of 10 GHz is obtained centered on 60 GHz frequency.

Abstract

12781; International audience; In this paper, an innovative 4G antenna solution operating in the 698-960 MHz band, is presented. It is composed of two radiating elements recombined in a single feed antenna-system using an integrated power divider/combiner, synthesized thanks to five lumped components. Simulations using realistic SMD (Surface Mount Devices) components allow reaching a matching better than -6 dB, confirmed by measurement and an average total efficiency of 30% over the full frequency band. These results are benchmarked with the performance of measured commercial handset antennas, demonstrating a key improvement of the achievable bandwidth and total efficiency. Proposed solution seems promising in order to address 4G wideband antenna design challenges.

Abstract

The inverse scattering problem of finding the optimal shape of 2D or 3D metallic or dielectric objects has received a growing attention in the last decade using different strategies either deterministic or stochastic approaches. Here we describe the development of an inverse scattering method based on a surface integral formulation of the EM problem for finding the solution of an inverse scattering problem, which is the optimal shape of planar antennas illuminated by plane waves or dipoles from the minimization of a functional involving the desired imposed constraints (e.g. an ideal radiation pattern known at a single frequency or for a wide frequency band). The state problem is solved numerically using a moment method (or variational principle) with triangular meshes. Many inverse scattering algorithms based on gradient methods are using forward and adjoint problems for calculating the cost function derivative. Here, in order to avoid the use of an adjoint problem and to deal with a more general method, we are calculating directly the derivative of the cost functional. In this way, we have directly access to the sensitivity of the cost functional versus parameters we are interested in. After calculating the shape derivative of the cost functional, we develop an optimization procedure according to the Level Set method. This method based on an implicit representation of the antenna boundary and the speed allows reconstructing a new planar triangular mesh structure at each iteration to decrease the value of the cost functional and performing possible several topological changes. A quasi-Newton method for optimizing the parameters of specific geometries has been also developed and applied to the design of a 2D period structure such as a Frequency Selective Surface (FSS).
