Millimeter-Wave Passive Components and Six-Port Network Analyzer in Dielectric Waveguide

A cost effective scheme of fabricating millimeter-wave passive components in dielectric waveguide has been conceived and a computer program has been written for analyzing their frequency responses. By inlaying Teflon guides in the properly designed contours cut in a low dielectric constant foam material, passive components such as quadrature hybrids, in-phase power dividers, and six-port network analyzers have been developed. Design and performance data are presented.
