Abstract

International audience; Les guides d’ondes en technologie « Ridge Gap Waveguide (RGW) » offrent naturellement de faibles atténuations linéiques, ils sont peu dispersifs et ils sont potentiellement utilisables sur des larges bandes fréquentielles. Ce papier décrit l’optimisation de la bande passante et de l’impédance caractéristique des RGW. Des études numériques sont réalisées pour générer des abaques qui relient les paramètres géométriques du RGW aux propriétés électromagnétiques du mode guidé.

(Received December 15 2011) (Revised December 20 2012); International audience; This paper presents a comprehensive study on the design of a 30 GHz, circularly polarized (CP), single horn-fed, metallic electromagnetic band gap (EBG) antenna. Three different approaches have been studied in order to create a 20 dBi antenna with an axial ratio (AR) lower than 1 dB over a 500 MHz bandwidth. Based on theoretical and experimental results, a conclusion is given on the best solution to obtain the desired characteristics. Perspectives and guidelines are also given for the design of multi-feed EBG antenna as a reflector focal feed for Ka-Band Space Applications.

Except at 3.7 GHz and for θ lower than −25° in the plane () equals to 0°, the modelized structure provides an axial ratio lower than 3 dB, over a wide angular aperture of 60° and over a bandwidth of 5.3% ([3.7 GHz-3.9 GHz]). It has a very low height of 11.9 mm (()/7 at 3.8 GHz). A prototype has been manufactured, and the measured performances, considering the tolerance of the measurement base (±0.5 dB), are quite similar to the simulated ones.

Abstract

International audience; This letter presents a first step toward the design of an enhanced multifeed EBG structure that serves as a focal-plane array for a Ka-band reflector for space applications in the 29.5-30-GHz band. The desired Earth coverage is the starting point for the antenna design. As shown in this letter, significant coupling can deteriorate the performance of the multifeed EBG antenna. In order to demonstrate this, the results are compared to those of the single-feed reflector antenna. Filters are then connected to the multifeed antenna ports to control the coupling in a constructive way and obtain good radiation characteristics. Finally, the global feed architecture (EBG structure + filters) is used to illuminate a reflector antenna in order to characterize the antenna performance (C/I ratio, EoC gain).

Abstract

International audience; This paper presents an analysis of different multi-feed EBG solutions, in order to choose the best one which provides overlapped apertures and promises good functioning as a reflector focal array. Two main structures will be studied: the matched and unmatched antenna. Both structures present different kinds of interference and coupling between feeds which disturb the performances of the antenna, especially the radiation. That is why suited filtering functions for each solution will be studied in order to isolate feeds and reconstruct the disturbed radiation. The investigation of all structures and their required filtering functions will lead us to the final promising solution which is the matched multi-feed EBG antenna.

Abstract

This letter presents an original solution to solve the matching problem of the circularly self-polarizing electromagnetic band-gap (EBG) antennas. More precisely, a comprehensive method to design a self-polarizing EBG antenna will be detailed. This kind of antenna had been designed before, but it was very poorly matched. An iris-based matching system has been used here, which produced a satisfying return loss while deteriorating the axial ratio (AR). An original device will be introduced, which allowed us to compensate for this degradation. Finally, to validate this new structure, a 20-dBi antenna working around 9 GHz and showing an AR lower than 1 dB over a 100-MHz bandwidth has been conceived, realized, and successfully measured.

25. Enhanced EBG resonator antenna to feed a reflector antenna in Ka band

Abstract

International audience; Recent studies have shown that a multibeam reflector antenna could be illuminated by a multifeed electromagnetic bandgap (EBG) structure, in order to achieve a high gain multispot coverage with the simple "one feed by beam" concept and only one aperture. This letter deals with the design of a metallic EBG antenna in the Ka band, feeding a side-fed offset cassegrain antenna (SFOCA) for a European multispot coverage. This reflector presents a high focal-length-to-diameter ratio limiting the defocusing effects for multibeam applications. It, therefore, requires focal feeds with a high directivity and a good radiation pattern quality. The well-known drawbacks of an EBG antenna are the narrow radiation bandwidth for high directivities and also the high sidelobes level reducing the reflector antenna efficiency. Consequently, the work presented in this letter consisted in improving the EBG antenna performances by using a more efficient feed. The replacement of the usual microstrip patch by a horn allowed to double the radiation bandwidth while decreasing the sidelobes level (-15 dB) of a 24-dB EBG antenna. A metallic prototype excited by a single horn has been manufactured at 30 GHz, and the measurements agree with the simulation. This device with one feed allows good SFOCA performances, similar to those obtained with a conventional focal feed like a Potter horn.

Abstract

We report the numerical and experimental investigation of a highly directive Fabry-Perot (FP) cavity antenna based on a metamaterial, operating in the microwave regime. Numerical simulations using finite element method and reflection-transmission microwave measurements have been performed and a good quantitative agreement has been observed. Measured return losses and radiations patterns done in an anechoic chamber agree very well with the simulated ones. The potential application of the proposed FP cavity antenna in a non-contact breathing sensor is proposed and evaluated. Experimental record and frequency spectrum for respiratory movements of human-being (voluntary under test) are presented. The low cost and simple fabrication process of the proposed FP cavity antenna make it very promising for its integration in modern telecommunication systems. [ABSTRACT FROM AUTHOR]

Abstract

This article introduces a new model of base station antenna used to communicate with mobile vehicles such as cars, trains, etc., providing high data rate for passengers on bord. This is a high gain sectoral electromagnetic band gap antenna, to limit the number of base stations along the covered way and to improve the wireless communication system. In this work, the base station antenna, which operates on the 5.47-5.725 GHz mobile WiMAX band, is designed and realized. Measurement and simulation results are shown. © 2010 Wiley Periodicals, Inc.
