Abstract :
A substrate integrated waveguide (SIW) circulator is proposed and demonstrated in this work that can facilitate the integration of planar active components with high-Q passive components. Very satisfactory experimental and theoretical results are provided, at 22 GHz, for a degree-2 junction circulator using a post resonator. It also includes experimental results on the classic gyrator circuit of this type of junction.
