Abstract
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.
Claims9
A dielectric filter for a predetermined frequency, said dielectric filter comprising:
- a signal input/output circuit;
- and
- a dielectric resonator coupled to said input/output circuit and including:
- a slot line comprising a first slot electrode having a first spiral slot and a second spiral slot disposed adjacent to a first surface of a dielectric layer, said second spiral slot being arranged in a line symmetrical relationship relative to said first spiral slot;
- and
- a shielding conductor provided at a predetermined distance from said first slot electrode,
- wherein said dielectric resonator is resonant at said predetermined frequency.
