Abstract
The proposed MFA is a complex, highly integrated architecture comprising a number of distinct radiating structures in a very compact package. The antenna design centers around a pair of conical radiators, which are DC (Direct Current) connected to the chassis/fuselage of the aircraft, as required in MIL-E-5400. These conical radiators are shared for simultaneous operation on 30-88 MHz, 118-174 MHz, 225-400 MHz and 960-1220 MHz. At the top of the conical radiator structure, there is a dual band (1575 & 1227 MHz) or broadband GPS patch antenna element, which incorporates a DC short circuit at its center. This patch exploits the height and ground plane provided by the top surface of the taller cone. In doing so, the GPS patch has improved performance at low elevation angles. The area available, and support structure, for the GPS patch could also support more sophisticated GPS antenna technologies as they become available.
