Abstract
A lightweight phased array antenna systems that is conformable to an aircraft fuselage combines air-filled cavity-backed slots with printed circuit elements for operation in two or more frequency bands. The printed circuit elements are separated from a conductive ground plane in which the slots are cut by a dielectric honeycomb material. The slots and printed circuit elements are individually excitable by a multiband feed network and transmit/receive modules for operation in the UHF band and S band or L band, respectively.
