A Wideband Finline Power Divider in a Metallized Plastic Housing: Design and Performance

This paper describes the design and performance of a wideband power divider which utilizes finline technology and is housed in a metallized plastic housing. The power divider exhibits excellent performance across the entire waveguide band demonstrating its feasibility in the design of wideband millimeter wave feed networks. To the author´s knowledge this is the first published report of an E-plane circuit housed in plastic.
