An improved injection molded radiator assembly and antenna assembly can be made using multiple such radiator assemblies. The radiator assembly includes an injection molded radiator enclosure that forms an RF waveguide channel. A circuit/RF probe subassembly is mated to the radiator enclosure that houses a circulator assembly, input and output connectors, and an RF probe. An environmental plug is disposed in the radiator enclosure to seal the RF waveguide channel from the external environment.

A suspended stripline corporate feed with an orthogonal transition to a coaxial transmission line at each of its input/output ports. Alternate I/O ports are pointed in opposite directions so that devices on both sides of the feed can be serviced by the same circuit. The cover for the feed is made out of injection molded, copper plated plastic. When utilized to distribute RF energy to T/R modules in an Active Array, the feed is machined as an integral part of the heat exchanger which cools the modules.
