Abstract:
Waveguide-to-microstrip transitions are essential elements for mm-wave transmitters and receivers. This paper presents an optimized transition with a relatively simple geometry and a minimum of compensation structures in order to mitigate sensitivity to fabrication tolerances. Almost 5 GHz bandwidth is achieved around 30 GHz, with an insertion loss of less than 0.25 dB. The transition can be implemented with a hermetic sealing.

Index Terms:
Waveguide transition, microstrip, electromagnetic simulation, hermeticity.
