High-frequency transmission line transitions

Abstract

This paper demonstrates the use of modern electromagnetic simulation software to design and develop a selection of three novel transmission line transitions, for operation at mm-wavelengths, and an improvement in the performance of existing transitions. Specifically, our three case studies analyse (i) a microstrip-to-stripline transition, (ii) an inverted microstrip transition, and (iii) a stripline-to-finline transition. The important concepts are described and the tools available are explained. A number of novel and effective designs are presented as examples.
