Paper Abstract

A type of E-plane double-Y junction, or YY-junction, circulator has been developed based on the nonradiative dielectric waveguide in Ka band. The operating principle of the circulator was analyzed by the theories of the polarization wave and the eigen network. The structure of the YY-junction is beneficial to enlarge the bandwidth with the structure-minimized. Experimental results show that this circulator is of good performance. The central frequency is 34.5GHz, the 1.5dB insertion loss and 20dB isolation bandwidth is about 1.3GHz.
