Design and Analysis of 5G Broadband Elliptical Cut Octagon Patch Antenna

Abstract

In this paper, a 5G Broadband Elliptical Cut Octagon Patch Antenna is designed whose operating frequency band is from 20.82- 22.95GHz, 25.13-28.46GHz. In this antenna, FR4 substrate whose dielectric constant is 4.4 and loss tangent (tan δ) is 0.002 is utilized as substrate. This antenna has a compact size of 15×25×1.6mm3 and has a radiation efficiency of 92.1%. In order to increase the band of frequency of an antenna, two similar elliptical cut octagon patches are added to form a Broadband Antenna. The resultant microstrip patch antenna is a 5G Broadband Elliptical Cut Octagon Patch Antenna.
