Abstract

In this paper, a broadband microstrip line-to-waveguide transition has been pre- sented for millimeter-wave module applications. For wide bandwidth applications, the radial microstrip line (MSL) probe and extended GND plane on the low-loss organic dielectric sub- strate are designed. The designed and tested performance of the transition is characterized in terms of an insertion and return loss. Considering the loss contribution of the cable adapter and waveguide transition for the measurement, the loss of the fabricated transition is analyzed as −1.88 and −2.01 dB per a transition at 70 and 80 GHz, respectively and its bandwidth for reflection at −10 dB is 26 GHz from 67 to 95 GHz.
