Butler matrix based six-port passive junction [PDF]
2014 IEEE Topical Conference on Wireless Sensors and Sensor Networks (WiSNet), 2014 In this work we propose the utilization of the Butler matrix as a six-port I/Q demodulator. The inherent symmetry of its topology allows to overcome the intrinsic amplitude and phase imbalances of the traditional approaches making it more suitable for the design of high performance six-port networks. To demonstrate the validity of the proposal a Butler
