A novel T-junction waveguide power divider with anti-phases and broad bandwidth

Abstract

A novel integratable planar T-junction waveguide power divider with anti-phase outputs and full bandwidth of standard WR28 waveguide is proposed. It is basically a E-plane waveguide T-junction with its input port rotated around the axis of the two output ports by 90 degrees to form a planar structure. In order to verify the concept, a standard waveguide port THE junction divider is designed as an example. From the results, the reflection coefficient is lower than −20dB and phase difference between the two output ports is within 180 degrees in the full bandwidth from 26.3 to 39.4GHz.
