Single feed compact millimeter wave antenna for future 5G applications

Abstract

In this electronic paper, we will present the design and numerical simulation of a compact single-layer millimeter wave antenna for the future fifth generation (5G applications), excited by a microstrip line. Its design is based on a rectangular patch with notches of different geometries mounted on a dielectric substrate. The proposed antenna operates at two different resonance frequencies, 28.00 GHz and 38.00 GHz. The numerical resolution of the maxwell equations using the finite element method (FEM), shows that the antenna can provide two bandwidths around 921 MHz (3.29%) centered at 28.01 GHz and 1.0451 GHz (3)., 72%) centered at 38.03 MHz. GHz. The reflection coefficients are −23.8112 dB for (fr)i = 28.01 GHz and −17.0898 dB for (fr)2 = 38.03 GHz. The gain of the antenna varies from 8.0527 dB for the band below 8.2869 dB for the upper band.
