Abstract

In this paper a novel V-band diplexer, based on the newly introduced groove gap waveguide technology is presented. The diplexer structure consists of an H-plane T-junction and two RX and TX filters having 1.5% relative bandwidth at 59.5GHz and 62.5GHz center frequencies, respectively. Also, two groove gap waveguide to WR-15 transitions are designed. The main advantages of the groove gap waveguide diplexer compared to the classical rectangular waveguide diplexer are that there is no need for electrical contact between the top and bottom metal plates, and it adds an opportunity of packaging the active transceiver circuits together with the diplexer. The design procedure and the simulated results are presented.
