The manuscript represents a metamaterial-inspired superstrate patch antenna with a multiband response. The design consists of three superstrate layers over the patch antennaand SRRloaded over parasitic patches. The performance observation is carried out for 2–10 GHz. The simulation and fabrication are taken into consideration, and comparisonsbetween both of them are included. FR4 is used as a substrate material which helps reduce the structure's cost. The metamaterial approach is incorporated over superstrate regions for the improvement of results. The superstrate approach helps for enhancing the strength and Bandwidth of the design. Impedance response is analyzed for different resonating frequencies to check the metamaterial response. Two types of Parametric Analysis are considered to achieve the targeted goal, like changing feed position and the gap among superstrate layers. The presented work shows eight bands of reflectance response with a minimum value of − 44.83 dB with a Bandwidth of 3.139 GHz, peak directivity of 3.16 dB, a gain of 8.02 dB at 9.04 GHz, maximum E-field distribution of 1.160 × 105 v/m at 6.52 GHz. Presented work compared with other design structures to identify the improvement. Many wireless communication-related applications like military, WiMAX, and Maritime mobile services.

A planar modified Sierpinski-Meander hybrid fractal antenna suitable for future wireless communication networks capable of exhibiting heptaband behavior has been presented in this paper. Proposed radiating structure is obtained by combining a modified Sierpinski gasket and Meander like antenna (for lower frequency) to obtain a hybrid structure exhibiting multiband behavior. Difficulty of designing a complex fractal structure has been eased by using scripting method (*.vbs) in HFSS obtained from IFS and MATLAB. Proposed antenna has partial-defected L-shaped ground structure which helps to obtain higher values of Gain. It has dimensions of 54 × 46 × 1.6 mm and resonates at 2.4, 4.437, 5.38, 7.01, 7.60, 8.41 and 9.09 GHz which covers useful applications like Bluetooth, WLAN, Wi-Fi, ISM, RFID, 4G/LTE, radiolocation and mobile/fixed satellite service. Prototype of the proposed structure is fabricated on FR4 substrate and tested. Measured results are analyzed and compared which are in good agreement with the simulated ones. [ABSTRACT FROM AUTHOR]

This paper presents a compact Multiband hybrid fractal antenna designed for mobile wireless applications it has planar structure and suitable for mobile applications at low cost. The proposed antenna structure is obtained by integrating a Koch curve and Minkowski curve. It exhibits multiband behavior, acceptable values of return loss, VSWR and gain in-spite of its compact size and less complexity. The proposed antenna design has been examined up to 2nd iteration of the new fractal geometry. The simulated results exhibited seven bands of operation covering some important frequency bands like GPS (L = 1227.60 MHz), bluetooth (2.41-2.49 GHz) of ISM band, WLAN 802.11 a/b (5.15-5.35 GHz) and other bands covers applications like mobile/fixed satellite and aeronautical navigation (3.876-4.375, 6.6188-7.0045, 7.9698-8.3373 and 9.1648-9.6214 GHz). Proposed antenna is designed by using scripting method of HFSS using MATLAB. [ABSTRACT FROM AUTHOR]
