Abstract
A dielectric TEM resonator, whose resonant frequency is adjustable in both directions after being incorporated in a circuit, is disclosed. A first dielectric TEM resonator comprises a metal member disposed near an open end of a resonator body and coupled to an inner or outer conductor of the resonator body. The resonant frequency is adjusted by adjusting a distance between the open end and the metal member. A dielectric material of a second dielectric TEM resonator is partially exposed, and a dielectric board for mounting the resonator body is also exposed in a corresponding part to the exposed part of the dielectric material. The exposed part of the dielectric board is partially covered with a metal plate. The resonant frequency is adjusted by adjusting the covered area.
