Abstract:
A dielectric resonator-to-microstrip transmission line coupling configuration, comprising:a ground plane; a dielectric substrate disposed on the ground plane; a dielectric resonator mounted on a surface of the dielectric substrate and configured to resonate in an intrinsic non-radiating hybrid electromagnetic mode; a wall mounted substantially perpendicular to the dielectric substrate surface and configured as a mirror for conceptually forming an image of the resonating dielectric resonator; and a microstrip conductor mounted on the dielectric substrate surface to form a microstrip transmission line, the microstrip transmission line being configured to generate a magnetic filed when transmitting an electromagnetic wave, wherein the wall is mounted a predetermined distance from the dielectric resonator to excite the intrinsic non-radiating hybrid electromagnetic mode to generate at least one transverse magnetic multipole inside the dielectric resonator, and wherein the dielectric resonator is mounted on the dielectric substrate surface near the microstrip transmission line to allow electromagnetic field coupling between the dielectric resonator and the microstrip transmission line while maintaining a high Q value of the dielectric resonator.
