Design of Printed RGW Crossover for Millimeter Wave Beam Switching Network

In this paper, the design of a printed RGW crossover for mm-wave beam switching network is proposed. The proposed device can be considered a good candidate in the design of beam switching network as it has a low loss with a wide bandwidth. The simulated results of the proposed crossover show a 13% fractional bandwidth centered at 30 GHz with an impedance matching level less than -20 dB and isolation level less than -15 dB. In addition, the proposed design has an average transmission loss of 0.5 dB over the operating frequency band.
