Multiband Patch Antenna Design for 5G Applications

This paper outlines concept of two multiband antennas suitable for 5G communication.One of which is designed in such a way that the resonating frequencies lies within the 450 MHz-6 GHz.This proposed antenna has resonating frequencies such as 2.4 GHz,2.8 GHz,4.1 GHz,5.5 GHz,5.9 GH, 6.6 GHz, 7.9 GHz and 9.3 GHz. Another multiband antenna operates in millimetrewaveband(24 GHz-86 GHz) resonating at 14.601 GHz, 23.3.01 GHz and 28.9 GHz.The substrate chosen for the designs is FR-4 for.r=4.4 dielectric constant and designed using HFSS software.The proposed antennas have low return loss, high gain and high directivity and low VSWR. These patch antennas are suitable not only for 5G applicationsbut also for WiFi,WiMax, Bluetooth and WLAN applications.
