A new W-band H-plane T-junction combiner

This paper reports a novel low-loss H-plane combiners at w-band. The combiner is turned with the employment of a two-double triangular prism in the junction area, which makes the H-plane T-junction achieves good impedance matching performance during a broad frequency band. Proof of concept was achieved by calculation and simulation, a copper sample is fabricated. The results show that insertion loss was lower than 0.7dB, and the amplitude imbalance was within 0.6dB.
