Design and Analysis of Microstrip Antenna for 5g Applications

Abstract

A new proposed antenna is presented in this article for 5G applications. The dimensions of this antenna are (32×32×0.8) mm³. The antenna that is suggested is built upon FR-4 epoxy dielectric substrate, with a loss tangent of 0.025 and relative permittivity of dielectric is 4.3 and, on the top layer of this substrate a polygon patch is etched with specific dimensions, also a ground plane on the bottom layer of the substrate is built. The patch of the antenna is fed from a microstrip feed line with a 50Ω characteristic impedance. The proposed antenna operates at 3.6 GHz as a resonance frequency with a bandwidth of (3.15 - 4.3) GHz, and gain (3.3) dBi at the operating frequency, these characteristics are suitable for 5G applications. To attain the targeted bandwidth and gain, distinct slots are carved onto both the patch and ground plane. The simulation outcomes are gathered using CST-MW 2020.
