Abstract
A dielectric resonator is formed on a dielectric substrate. A pair of microstrip lines is formed to be electromagnetically coupled with the dielectric resonator. An end of each of the microstrip lines is open to define an open end while another end is arranged to approximate to the dielectric resonator for defining a node. A cathode and an anode of a varactor diode are connected to the node of each of the microstrip lines respectively.
