Coplanar waveguide coupled with TE01γ mode dielectric resonator

This paper newly proposes that coupling between a coplanar waveguide (CPW) and a TE_01γmode dielectric resonator (DR) can be realized for a parallel resonant characteristic as the DR coupled with a microstrip line. Coupling characteristics have been investigated by placing the DR on a special support above the CPW and by moving the DR away from the center of a slot of the CPW to the ground plane. FEM simulation (HFSS) results in terms of S-parameters agree well with measurement results. Finally, loaded Q values of the DR coupled with a CPW are compared with those of the DR coupled with a microstrip line. The comparison demonstrates that a DR coupled with a CPW has slightly higher loaded Q than that coupled with a microstrip line has.
