Analysis and Design of a New Type of Millimeter Wave Integrated Waveguide to Microstrip Transition

A new type of waveguide to microstrip transition integrated on a single dielectric substrate is proposed. The transition is composed of a microstrip circular resonator and a coplanar waveguide probe which convert the H 10 mode in a rectangle waveguide to quasi TEM mode in a microstrip. A full wave analysis software is adopted in simulating and optimizing the structure. The designed transition is tested by millimeter wave network analyzer. The results show that the insertion loss is less than 0.4 dB with the reflection loss less than -14 dB over about 1 GHz bandwidth in Ka band. The transition has wide applications in corresponding millimeter wave microstrip integrated circuits and systems.
