Patent Images
1. A dielectric resonator circuit comprising:
- a plurality of resonators, each comprising a body formed of a dielectric material, said body having a first end and a second end, said body varying in cross-sectional area between said first and second ends;
wherein said plurality of resonators are positioned relative to each other such that a field generated in each resonator couples to an adjacent resonator; and
wherein each of a first and second of said plurality of resonators are adjacent to a third of said plurality of resonators, wherein said first and second resonators are alternate resonators positioned such that a field in one of said first and second resonators cross-couples directly to the other of said first and second resonators.

Abstract
A cross-coupled dielectric resonator circuit. Resonator circuits in accordance with the invention may be used to build low-loss compact filters, oscillators, and other circuits, particularly microwave circuits. The resonators are arranged relatively to each other within an enclosure in a very efficient and compact design that enhances adjustability and coupling between adjacent resonators and the cross-coupling of alternate resonators.
