Abstract:
A bonded air strip microwave transmission line assembly for satellite antennas and beamforming networks having low radio frequency energy loss, comprising:(a) a thin central conductor strip; (b) an opposed pair of upper and lower solid dielectric core layers of lightweight plastic foam having a low dielectric constant and low radio frequency energy loss adhesively bonded to confine the conductor strip therebetween; (c) an opposed outer pair of thin conductive faceskins, each adhesively bonded to the outer surface of one of the dielectric core layers; (d) at least one opening through said conductive faceskins and through the dielectric core layers, and (e) a continuous conductive material which enters the opening to provide conductive contact between the conductive faceskins to suppress parallel plate propagating modes during use.
