High performance & Compact Size Of Microstrip Antenna For 5G applications

Abstract

Millimeter-wave (MMW) systems are finding various commercial applications with the increasingly growing demand for bandwidth. Microstrip patch antennas (MPA) have low-profile advantages and ease of processing. However, due to the geometry of the patch on a thick dielectric substrate, the performance (gain, bandwidth) of the antenna will be degraded. An engineered patch shape that directs the radiation can be designed with promising characteristics such as gain and bandwidth. The proposed shape of the patch antenna is presented in this paper. To characterize their performances, the numerical results (simulations using HFSS) for the designed antenna are presented. The proposed microstrip antenna resonates at 93 GHz with a realized gain of 8.2 dB and a bandwidth of 5 GHz. The results of the simulation show significant changes in the radiation pattern and bandwidth that can be used for Passive MMW Imaging purposes in the MAP array.
