A simple circular-to-rectangular waveguide transition

We describe a novel one-step TE/sub 11/-mode circular waveguide to TE/sub 10/-mode rectangular waveguide transition. The primary advantage of this device over existing transitions is its ease of fabrication. We have incorporated our transition into a number of waveguide components operating at V-band. The transition's measured return loss exceeds 15 dB over a 12% bandwidth centered near 60 GHz.
