Performance Analysis of Microstrip Grid Array Antenna on Different Substrates for 5G Mobile Communication

Abstract

This paper investigated the performance and characteristics of microstrip grid array antenna (MGAA) on three different substrates which are Rogers RT5880LZ, Taconic RF-43, and Fr-4. For this work, the proposed MGAA has been designed at 15 GHz for 5G mobile communication application. The proposed microstrip grid array antenna consists of 12 cells block with 19 radiating elements and was feed using the 50 Ω coaxial port from the ground plane. A comprehensive study on the effect of substrate on the performance of MGAA is carried out. S-parameters, gain, and efficiency of MGAA on all those substrates have been used as parameters in determining the performance of proposed antenna in order to fulfill the design criteria for 5G mobile communication application. The design and simulation process of MGAA was done in CST Microwave Studio Software
