Dielectric resonator, inductor, capacitor, dielectric filter, oscillator, and communication device

摘要

A dielectric resonator includes a slot line constructed by providing a slot electrode having a spiral slot at either an external face of a dielectric layer or inside the dielectric layer and a shielding conductor provided at a predetermined distance from the slot electrode. The slot line is employed as a resonant line so as to provide a dielectric resonator, an inductor, a capacitor, a dielectric filter, an oscillator, and/or a communication device.
