Effects of Microstrip Array Failures in a Smart Antenna System for 5G Mobile Communication

Abstract

The main objective of this research is to investigate the effects of element failures in an Antenna Array. The proposed Uniform Linear Array (ULA) of Microstrip Patch Antennas is designed to operate at 3.5 GHz for the upcoming 5G applications. The proposed model is designed and optimised using HFSS. Experimental study is conducted to analyse the effects of failure in terms of Gain, Mutual Coupling and Side Lobe Ratio (SLR). It was found that Gain reduced by 1.3 dB, decrease in SLR by 50% and decrease in Mutual Coupling by 3.42 dB is observed.
