High Directivity and High Gain Microstrip Patch Antenna for 5G Application with Defective and Suspended Ground Plane

Abstract

The paper delivers a unique 5G microstrip antenna design capable to be used in today's millimeter-wave applications at resonant frequencies of 26.72 GHz, 32 GHz, and 37.97 GHz. It is a design achieved after performing alterations to the front patch, ground, and substrate along with the introduction of Defected Ground Structure and suspended ground plane techniques to attain higher directivity, Gain, S-parameters, VSWR, and optimal efficiency. The proposed antenna has been made by utilization of copper(annealed) for the design of the front patch and ground, alongside the Rogers RO3003 (lossy) for the main substrate as well as Rogers RT6010LM for suspended ground. We achieved the required results using Computer Simulation Technology (CST) software.
