Abstract

The waveguide to microstrip transition circuit is used as the energy transition interface in millimeter wave and terahertz systems, and its energy coupling efficiency will directly affect the performance of the system. In this paper, based on the probe coupling form and gradual processing of the microstrip line, a broadband waveguide to microstrip line transition structure with a center frequency of 140 GHz is designed. The simulation results show that in the 110 GHz~170 GHz frequency band, the return loss of the designed transition structure is greater than 14.6 dB, and the insertion loss is less than 0.2 dB.
