Broadband transition between microstrip line and WR15 rectangular waveguide using low‐temperature cofired ceramic process

Abstract: A compact aperture coupled patch type microstrip‐to‐waveguide transition at V‐band is proposed and fabricated using low‐temperature cofired ceramic process. It uses the aperture coupled microstrip feed and the parasitic patch antenna radiating into the waveguide to improve the insertion loss and the bandwidth. As a result of experiments, low‐transmission loss and high‐return loss are realized at the design frequency of 60 GHz. For a 10‐dB return loss, a relative bandwidth of 13.8% is obtained for a fabricated … Show more

“…Based on the relative position between the waveguide and the microstrip line, the previous designs can be classified into 2 distinct types including the vertical transitions and the parallel ones. The probe transitions [2][3][4][5][6][7][8][9][10][11] and the slot ones 12,13 are 2 typical vertical transitions. It means the microstrip structure penetrates into the waveguide through its wall, and the transmission directions of the microstrip and the waveguide are orthogonal.…”
