Abstract

PURPOSE:To make change the characteristic impedance of the resonator easily, by covering the lambda/4 type resonator with a dielectric cylinder and changing the position. CONSTITUTION:When the dielectric substance 6 is apart from the tip of the resonator rod 1, the dielectric constant between it and the console 2 is almost 1. When the dielectric substance 6 coveres the resonant rod 1, the dielectric constant is 1 or more and the resonant frequency gradually decreases. The electric field or electric lines of force of the resonator is vertical to the resonant rod independently of the position of the dielectric substance 6, the density of distribution is not greatly changed, and the current flowing on the surface of the resonant rod 1 and the console 2 is not concentrated on a part but is uniform, resulting in no degradation of Q. Since the thickness of the dielectric substance is constant, even if the cylinder is moved due to vibration, no effect by the dielectric substance is caused. Further, the thickness is controlled and the resonant frequency can be adjusted in good manner.
