A novel H-plane based T-junction waveguide power divider for WR-10

Abstract

In this paper, a novel H-plane T-junction waveguide power divider that can operate on the entire W-band is in troduced, it can save more space in many applications. It solves the problem that the traditional H-plane T-junction waveguide power divider cannot cover the entire W-band and the reflection coefficient is less than -20dB. A H-plane T-junction power divider for the size of WR-10 waveguide are designed and fabricated used a blocking plate, two grooves and a stepped input matching transformer. The measured results agree well with the simulations and It is suitable for the whole frequency band of W, and the reflection coefficient is less than -20dB. The optimized design size can also be used for other waveguides.
