Abstract

A single-layer broadband transition between air-filled rectangular waveguide (ARW) and substrate integrated waveguide (SIW) operating in W band is proposed. Voltage and current probes are employed to implement the transition. A back-to-back prototype of the proposed transition is designed, fabricated, and measured. Good agreement of the simulated and measured results are obtained. From 80.2 to 98.1 GHz, the measured results show that the insertion loss (IL) is less than 1 dB and the return loss (RL) is better than 10 dB.
