Performance analysis of high gain beamforming conformal array for avionic applications

摘要

In modern wireless avionic systems like aircraft, radar, missile and satellite communication, demand wideband or multiband antennas to improves the data rate transmission. In this paper, two slotted patches are asymmetrically assembled on a cylindrical thick foam substrate to obtain high gain, wide bandwidth and wide angular coverage for avionic applications. The reported antenna is operating in 3.8 GHz band with a bandwidth of 421 MHz, E-plane –3 dB HPBW of 150° and H-plane HPBW of 62°. The measured realised gain of the antenna is above 6 dBi throughout the operational band. The prototype of the proposed configuration is fabricated and showing good agreement with simulated results.
