ABSTRACT:
A Q enhanced dielectric resonator circuit includes a metal enclosure having interior walls defining a chamber. Secured to at least two interior walls is a dielectric substrate. Flatly mounted to at least one side of the dielectric substrate is a substrate stripline. A dielectric resonator is secured to the dielectric substrate at a selected distance from the substrate stripline. The dielectric substrate is positioned a sufficient distance from a ground plane such that the magnetic field lines of the dielectric resonator do not significantly interact with the ground plane. The dielectric resonator is also positioned such that there is substantial coupling of the magnetic field lines of the dielectric resonator with the magnetic field lines of the substrate stripline.
