Transient and broadband analysis of air craft fixed-wire antennas

Certain aircraft are equipped with wire antennas that operate in the HF regime (3-30 MHz). One type that is being used as a communications antenna is shown. The antenna is being supported between an insulated mast on top of the fuselage and the leading edge of the vertical stabilizer. The aircraft itself forms an important part of any HF antenna since the main longitudinal aircraft resonances occur within the HF regime. Any analysis of an HF antenna must therefore include the presence of the aircraft. This is done in this paper by modeling the aircraft with a set of intersecting sticks. This model is known to adequately account for the aircraft response in the resonance region.
