Abstract

The authors propose an array in which a plane TEM (transverse electromagnetic) wave is excited in a parallel plate waveguide by a rectangular waveguide through feed slots cut in a back conductor. Its radiating part consists of an upper conductor plate in which a slot pattern has been etched. The configuration is suitable for linear polarization and dual-polarization use. The concept of a slot pair is adopted to suppress reflection and to maintain traveling wave antenna operation, which is confirmed by experiments. TEM plane wave excitation in the parallel plate waveguide has been confirmed, and the uniform aperture field distribution has been realized at the design frequency.<>
