Efficient HF Transmit Antennas Utilizing Platform Coupling and Reconfigurable Aperture
Virtual EM is proposing a solution for achieving electrically small high-efficiency VHF transmit antennas suitable for use on medium size Unmanned Aerial Vehicles (UAVs). In the proposed approach, maximum use of the UAV"s airframe for the antenna improves radiation efficiency while dynamic reconfiguration of the antenna aperture provides frequency tuning and hence lower noise floor. Feasibility has been demonstrated via simulations and limited prototyping in Phase I, and a fully functional prototype on a flight-worthy UAV will be built in Phase II.
