Abstract:

A new type of waveguide, the H-guide consists of two parallel metal plates and a dielectric slab sandwiched perpendicularly between the plates. Characteristics of the guide make it useful at frequencies in the millimeter-wave region. In comparison to a rectangular waveguide, the Hguide has greater cross-sectional dimensions, lower attenuation, higher power-handling capacity, and no requirement for electric contact between guide sections. The H-guide is studied theoretically and experimentally attenuation constants are calculated and measured, use of foam dielectrics is evaluated, and maximum transmitted power at breakdown is calculated. Usefulness of H-guide is demonstrated through design of several components such as transducers, bends, power dividers, and directional couplers. Author
