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

Abstract

This work presents and describes the design of a novel multilayer antenna structure based on metasurfaces for 5G mobile applications. The suggested antenna has good matching input impedance around 28 GHz, a bandwidth of 2.2 GHz, and an enhancement of gain in comparison with standard patch antenna. This antenna is mounted on two substrates; the first one is the foam, and the second is Roger’s substrate suitable for 5G mobile applications. The whole dimensions of the final circuit are 3.28x4.23mm2. The proposed antenna structure has a high gain, good matching of input impedance and an aperture angle of 57 ° which is more directive compared to the rectangular antenna element.
