Abstract
In a TM dual mode dielectric resonator apparatus, a cross-shaped TM dual mode dielectric resonator is provided in an electrically conductive case, wherein the TM dual mode dielectric resonator comprises first and second dielectric resonators integrally formed so as to be perpendicular to each other, and coupling grooves for coupling an operation mode of the first dielectric resonator with an operation mode of the second dielectric resonator are formed in the TM dual mode dielectric resonator. Sizes such as thicknesses, widths or the like, of the first and second dielectric resonators are different from each other for adjusting the resonance frequency
