Dielectric resonator capable of varying resonant frequency |
摘要 |
A dielectric resonator capable of adjusting a resonance frequency, reducing occurrence of a mode jump if it is applied to an oscillator and being manufactured at a low cost. The dielectric resonator has a pair of upper and lower opposing conductive plates; a dielectric substrate disposed between the conductive plates; a first electrode formed on one surface of the dielectric substrate, the first electrode having a first opening; a second electrode formed on another surface of the dielectric substrate, the second electrode having a second opening corresponding to the first opening so that a resonator is formed by a portion of the dielectric substrate disposed between the first and second openings; and a variable capacitor located in a portion of the dielectric substrate in which an applied electromagnetic field is confined in and around the resonator.
