Diplexer integration into a Ka-band high-gain gap waveguide corporate-fed slot array antenna
Paper in proceedings, 2017

A multilayer integrated diplexer-antenna array module for Ka-band high capacity point-to-point backhaul links is presented. The proposed module is composed of three unconnected metal layers with a simple mechanical assembly and no electrical contact requirements between the distinct layers based on gap waveguide technology. A 7th order hybrid diplexer-splitter with a novel architecture is successfully integrated into a ridge gap waveguide corporate distribution network of a 16×16 slot array antenna. The measured input reflection coefficients for both Tx/Rx channels are below -13 dB with measured total efficiency better than 60% in the designed passband. The measured isolation of gain between the two channels is more than 55 dB.
