Design and Analysis of an Elliptical Edge with Pentagon Slot Patch Antenna for 5G Applications

By Pendli Pradeep K. Jaya Sankar P. Chandra Sekhar

This paper presents a design of modified rectangular patch antenna with a pentagon slot and elliptical-shaped strip at the edge of the antenna for Sub-6G band 5G wireless applications. The proposed antenna excited using a 50-ohm coaxial cable transmission line. The overall dimensions of the substrate are 49.72 x 43.02 x 1.7 mm3 used on a Rogers RTDuroid 5880(TM) with relative permittivity of ∈r=2.2. The proposed antenna is simulated using Ansys HFSS Software at a resonant frequency of 3.2 GHz. The experimental and simulated results are matched well. The measured return loss value of the antenna is -20 dB at 3.2 GHz frequency, which can cover an impedance bandwidth of 150MHz. The proposed antenna provides a stable radiation pattern, radiation efficiency is 96%, and peak gain is 4.6 dBi. This antenna finds applications for WiMAX wireless broadband communication, radar, and commercial Wireless LAN in S-band.
