A Compact Double-Layer Groove Gap Waveguide Power Divider with High Isolation
Paper in proceedings, 2020

A compact double-layer power divider with high isolation between output ports based on the groove gap waveguide (GGW) is presented in this paper. A five-port 1-to-2 power divider is designed base on the gap waveguide technology. Then a 1-to-8 power divider is built up by connecting seven 1-to-2 five-port power dividers. To achieve a compact size, the 1-to-8 power divider adopts a double-layer structure. The top layer is the feeding structure of the power divider, and the bottom layer contains the loads. The simulated results show that the proposed power divider exhibits the impedance matching bandwidth for the reflection coefficient below -15 dB is from 23.7 GHz to 30.3 GHz, and isolations between the output ports is more than 18 dB.
