Abstract :
In this paper, a novel W-band waveguide power divider based on H-plane slot bridge is presented. The divider, relying on the H-plane waveguide multi-step couplers, consists of a coupling gap in the narrow common wall between two WR10 waveguides and two arc debosses in H-plane of the two waveguides. The power dividing is realized by adjusting the length of the coupling gap and radius of the arc deboss. The designed divider has a good performance over 80-90GHz. The amplitude balance of two output ports is within ±0.3dB; the reflection coefficient is less than -22dB and the isolation is greater than 22dB. The proposed structure allows the mechanical tolerance within 0.2mm.
