“…Using a new planar configuration such as a substrate integrated waveguide can handle the problem of high insertion loss for isolators [17,18] and also circulators [19,20]. The narrow bandwidth of the ferrite components has been addressed using another approach such as the edge-guided mode for ferrite nonreciprocal circuits, which can also introduce high non-reciprocity [21,22].…”

In this paper, a novel wideband gyrator based on a ferrite coupled line design approach and realized in coplanar waveguide configuration is presented. The ferrite coupled lines are proved to demonstrate typical unique properties. The design of the optimum coupled lines has shown an almost 1 dB/3 dB insertion loss for even/odd modes excitation respectively. Also, for single excitation, the power is divided at output ports with insertion loss almost equal to 3 dB and 5 dB, good matching and isolation between output ports (less than −15 dB). The bandwidth of the designed coupler is proved over the bandwidth of 7 GHz-11 GHz. As an application, a novel gyrator is introduced and covers the same coupler bandwidth. The performance of the gyrator is optimized using full-wave simulations.
