Modeling of Light Airborne High-frequency (HF) Antennas
Abstract
Performance of three lightweight, high-frequency (HF), airborne antenna designs are compared using FEKO method-of-moments modeling software. Of interest were the beam patterns near the ground. All three are upside down with -wave counterpoise wires at the top. The antennas are fed between the base and the counterpoises. Two are -wave monopole antennas while a third is a combination of cross-connected half and -wave coaxial lines. Field strengths reaching the ground at a distance of up to 10 km, with the antennas suspended about four wavelengths above a uniform real ground, were computed.
