An Unequal Power Divider Based on Ridge Gap Waveguide
Paper in proceedings, 2019

This paper proposes a novel unequal power divider based on the ridge gap waveguide technology. Different from the conventional T-junction power divider, the unequal power divider is realized by using a half-height pin structure with an inserted conductor plane. The conductor plane is printed on a thin substrate for the mechanical feasibility. The power division ratio can be controlled by the position of the inserted conductor plane. In this paper, a 1:2 power divider is designed to verify this topology. The reflection coefficient is below -20 dB from 26 GHz to 32 GHz with 20.7% impedance bandwidth and the amplitude discrepancy between the two output ports is about 2.92 dB. Meanwhile, the maximum value of the phase difference is below 12 degrees.
