摘要：
A novel methodology of the mode conversion between rectangular TE10 and TE20 mode based on the H-plane T-junction power dividing network is proposed in this paper. A mode converter operating in the H-band (220-325 GHz) was analyzed and designed. To decrease the port reflection caused by the T-junction discontinuity, a septum and two symmetric irises were introduced in the converter. Two identical rectangular TE20 mode converters joined back-to-back were manufactured by Nano-CNC machining and the electromagnetic properties were measured by using a vector network analyzer. A bandwidth of 228.8-293.1 GHz (64.3 GHz) for transmission coefficient S-21 around dB and port reflection S-11 around dB was measured. The measured results were in good agreement with the simulated ones and manifested high mode conversion efficiency.
