Abstract
The authors propose a novel feed structure to excite a plane TEM wave in a parallel-plate waveguide. The feed waveguide is composed of dense ly arrayed posts on the same laver as the parallel plate. The posts ca n be easily fabricated at low cost by making metalized via holes in a grounded dielectric substrate. Such a procedure results in a quite sim ple fabrication of the antenna. The feed waveguide is designed to obta in a uniform division, which is confirmed by measurements on a 40-GHz band model.
