Circuit with a dielectric resonator in the te01 - mode.

摘要

A resonator element (5) formed of a half or a quarter of dielectric cylinder contacts an electrically conductive plane (11) via the resonator element's radially cut side (5′) which includes the axis of the cylinder, accordingly, resonates in TE01δ-mode. On an opposite side of the electrically conductive plane there is provided an unbalanced transmission line, for example, of a strip line type or a coaxial line type. An end of the transmission line is electromagnetically coupled via a dielectric material in the transmission line or directly with the radially cut side (5′) of the resonator element (5) through an opening provided on the electrically conductive plane (11). Coupling circuit according to the present invention allows a compact overall circuit configuration.
