ABSTRACT:
The invention is a compact wave antenna system for use on an aircraft. The antenna is mounted on a boom made of a dielectric material extending from the rear of the aircraft. The antenna comprises a thin, flat conductor wrapped around the boom. A large, "capacitive hat" is mounted to the extreme rear end of the conductor. The main contributors to the performance is the use of thin, wide conductor design and its relatively long length. The width causes high shunt capacity and high RF current flow to the airframe from all sections of the compact wave conductor topped off the capacitive hat at the end. The thin conductor cross-section minimizes series inductance and improves the flow of RF current. Additional current flows due to the spiral section coupling to sympathetic polarities of the airframe and due to additional radiation from the directional discontinuities.
