DIELECTRIC RESONATOR CIRCUITS

摘要

The invention is a dielectric resonator circuit comprising a housing; first, second, and third resonators (502, 702) positioned substantially in a row within the housing with said second resonator positioned between the first and third resonators, wherein the resonators are positioned relative to each other such that a field generated in each resonator couples to an adjacent resonator; wherein the housing encloses the resonators and has a separating wall (530, 730, 830, 930, 1030, 1130, 1230, 1330) positioned between the first and third resonators (502, 702) in order to control electromagnetic coupling between the first and third resonators; and wherein said first separating wall (530,..., 1330) comprises a first end and a second end along a length thereof and wherein the separating wall defines an iris at the first end, the wall (530,..., 1330) comprising a main wall portion positioned substantially between the first and third resonators and an extension wall portion at the first end that extends at an angle from the main wall portion of said wall (530,..., 1330).
