- 論文の詳細を見る
A small circulator with a coplanar waveguide structure was confirmed to have nonreciprocal transmission characteristics by a high-frequency electromagnetic simulation based on a three-dimensional finite element method. The circulator consists of a hexagonal YIG ferrite substrate and a Y-junction with coplanar waveguide transmission lines. Operating at 7 GHz, the circulator has an insertion loss |S_<21>| of 0.69 dB, isolation |S_<31>| of 32.7 dB, return loss |S_<11>| of 32.2 dB, and bandwidth of 77 MHz. The nonreciprocal operation of the circulator is attributed to the wavy nonuniform distribution of the electric field in the YIG ferrite substrate.
