DESIGN OF NOVEL PATCH ANTENNA FOR 3.8GHz UAV WI-MAX APPLICATIONS

Abstract
Antenna plays vital role in the development of Unmanned Aerial Vehicles (UAV) in aerospace technology. In this paper, a novel patch antenna for 3.8GHz UAV Wi-MAX application is presented. The proposed antenna has novel fork shaped radiating patch along with modified ground plane with 20?16mm2 smallest dimension. The proposed antenna developed on the FR4 substrate with dielectric permittivity of 4.4 and height of the substrate is 1.6mm and loss tangent of 0.002 to achieve lower return loss possible. The proposed antenna simulated in an integral based solver simulation software called CST Microwave studio v2019 and obtained results such as Return loss -26dB with Bandwidth of 400 MHz, VSWR of 1.2, gain of 1.78dBi, Efficiency of 92%. This proposed antenna suitable for UAV Wi-MAX applications which uses 3.8GHz resonant frequency.
