Analysis of H-type Waveguide

Abstract

This report presents a theoretical investigation and the experimental results of a special kind of waveguide, H-guide. Physically, the guide consists of a dielectric strip sandwiched between two parallel metal plates. Electrically it is excited in a mode having no longitudinal current flowing in the metal and most energy is located in the dielectric. The fields in the air decay exponentially as the distance from the dielectric surface increases. The basic formulas which describe the behavior of H-guide are derived. Expressions which are used for the determination of the cut-off frequency, rate of field decay in the air and attenuation due to
