A Wideband Butler Matrix Based on Ridge Gap Waveguides for mmW Applications
A wideband butler matrix (BM) is designed based on ridge gap waveguides (RGWGW). The BM consists of several directional couplers, crossovers and phase shifters. The simulated S11/22 is below -10 dB from 25.6 to 33 GHz with a bandwidth of around 25.3%. Meanwhile, the isolation level is above 10 dB in the working band. Besides, the phase errors are within ± 10°. Each output port of the BM is terminated with two parallel dipoles with different length as the radiation element. This multibeam antenna has a stable radiation pattern. The maximum gain achieved for Port 1 and Port 2 are 13.71 dBi and 12.69 dBi respectively.
