Design and Simulation of IFF/ATC Antenna for Unmanned Aerial Vehicle

In aerial applications, for identifying friend and foe, Traffic control and air defense, a system called IFF (identification friend or foe) for military vehicles or ATC (air traffic control) for civilian vehicles is used. For unmanned aerial vehicles (UAVs), because of widely use, it is inevitable to use IFF/ATC systems for both air defense against enemy and traffic control. In this paper, an efficient antenna in terms of size and parameters (gain, VSWR, radiation pattern and impedance), is designed and simulated. Obtained results showed good performance comparing with civilian and military airplane antennas.
