Bandwidth Enhancement of Microstrip Patch Antenna Using Metasurface

Abstract

In this article, bandwidth enhancement of a microstrip patch antenna using a new kind of metasurface is discussed. This new geometry is used to generate new resonances in antenna and with an optimal position of the metasurface in relation to antenna we can overlap the resonances and obtain a large bandwidth. The proposed antenna showed a bandwidth from 5.1 GHz to 8.0 GHz what can it able to be applied in WiFi 5 and 6. Numerical results were obtained with Ansys HFSS software. A prototype was built and measurements for S11, Smith chart and gain were performed. Numerical and experimental results are in good agreement.

Monopole Antenna with Enhanced Bandwidth and Stable Radiation Patterns Using Metasurface and Cross-Ground Structure

“…The emergence of metamaterials with different resonator unit shapes has played a great role in reducing the complexity incurred due to the addition of extra structures, thus improving the performance of the antenna [ 26 , 27 ]. Metasurface structures are typically two-dimensional arrays of small scatters or apertures that are geometrically arranged in order to achieve some desirable electromagnetic behavior [ 28 , 29 , 30 , 31 ]. Metasurface structures such as frequency selective surfaces (FSSs) have been widely used to improve the low gain and narrow bandwidth performance of planar antennas owing to their low cost and small profile, in addition to their immense transmission and reflection potentials [ 32 , 33 , 34 ].…”

A new design of 5G planar antenna with enhancement of the bandwidth and the gain using metasurface

“…For these reasons, researchers have proposed different techniques and methods for meeting the requirements of 5G mobile communication such as the use of Defected Ground Structure (DGS), the partial ground plane permitting to improve the matching input impedance frequency band [1][2][3][4][5][6]. For gain and radiation efficiency, antenna array configurations can be used to improve them [7][8][9], among the technique which can enhance and improve the performances of the designed antenna we can use meta-surface [10][11][12].…”
