ABSTRACT:
A dielectric resonator having a line pattern that includes an electrode gap that defines a signal input/output portion provided on an open side, and a ground portion provided on a short-circuited side. The length L in a main direction of a portion of the line pattern in which the signal input/output portion and the ground portion face each other is smaller than one quarter the wavelength of a resonant signal of the resonator. A variable-capacitance element is connected to the signal input/output portion. One end of the variable-capacitance element has a positive potential and the other end of the variable-capacitance element has a negative potential.
