A wideband dual polarized bow-tie antenna for 5G applications

Abstract

A wideband dual polarized bowtie antenna for 5G applications is presented. The dual polarization is achieved by using two different bow-tie antenna elements placed in orthogonal orientation. The design consists of rectangular slots on the two arms of bow-tie antennas which enhances the port to port isolation. The unidirectional radiation pattern is obtained by placing a perfect electric conductor (PEC) ground plane at λ/4 distance. The radiating elements are designed to operate at 3.5 GHz. Measured results of the proposed dual polarized bow-tie antenna exhibit a bandwidth of 42.85% (3.1 - 4.6 GHz) and 11.4% (3.3 - 3.7 GHz) for a VSWR of < 2 and 1.5 respectively. An isolation of 28dB between the two ports and an average gain of 8.4 dB is measured for both the polarizations. © 2019 IEEE.
