Efficient Simulation of Wideband VHF/UHF Candidate Antennas for Unmanned Aerial Vehicle Platform Using FEKO

A variety of wideband antennas, including a blade antenna, a monocone antenna, and a number of wireframe permutations of the monocone antenna are simulated on an aircraft wing using the FEKO electromagnetic simulation software. The simulated return loss data is analyzed in order to select a suitable candidate antenna for potential inclusion as the radiating element in a direction finding system for an Army UAV platform. The results of this modeling effort demonstrate that FEKO is an excellent tool for efficiently modeling candidate antennas on large vehicular platforms and that the potential exists for its use as a calibration tool for direction finding antennas mounted on large Army aircraft platforms that cannot be measured in a standard anechoic chamber.
