An E-band Antenna-diplexer Compact Integrated Solution Based on Gap Waveguide Technology
Paper in proceedings, 2017
In this paper, a novel compact integrated antennadiplexer for Frequency-division duplex low latency wireless backhaul links at E-band is presented. The proposed solution is designed in a multilayer architecture with each layer having different functional blocks. The layers have been stacked on top of each other without any electrical contact requirement between them. This is achieved by using packaging property of gap waveguide technology. A corporate-fed 16 x 16 slot array antenna is integrated with a 5th order diplexer. The simulated reflection coefficients arc better than-13 dB for both input ports in the designed passbands. The simulated realized gains at the middle of channel 1 (73.5 GHz) and channel 2 (83.5 GHz) are respectively 31.8 dBi and 32.9 dBi, obtaining a high isolation of 50 dB between the two input ports.
