US 6,549,102 B2 · Quasi dual-mode resonator

Abstract

A dielectric resonator is provided having a cavity, a dielectric half disk resonator structure structure, and a support for the half disk resonator structure. The support isolates the dielectric half disk resonator structure from walls of the cavity. A straight edge wall of the dielectric half disk resonator structure couples to a dielectric/air interface within the cavity and forms an approximate magnetic wall. The approximate magnetic wall images the electric field perpendicular to the straight edge wall and supports a single-mode electric field within the half disk resonator structure. Multiple half disk resonator structures may be oriented within the cavity to support other, orthogonal electric fields. Multiple cavities may be coupled to each other through irises formed on the cavity walls.

Dependent claims

A dielectric resonator comprising:

a cavity housing;
a support mounted within the cavity housing;
a first dielectric half disk resonator structure mounted on the support and having a straight edge wall with a dielectric/air interface positioned adjacent to the straight edge wall, wherein the straight edge wall and the dielectric/air interface approximate a magnetic wall thereby creating an electromagnetic image of the electric field within the half disk resonator structure.

A dielectric resonator, comprising:

a first cavity containing a first dielectric half disk resonator structure, the first half disk resonator structure having a first straight edge wall and a first dielectric/air interface associated with the first straight edge wall;
a second cavity containing a second dielectric half disk resonator structure, the second dielectric half disc resonator structure having a second straight edge wall and a second dielectric/air interface associated with the second straight edge wall;
a cavity wall separating the first cavity from the second cavity;
and
an iris structure formed on the cavity wall coupling the first cavity to the second cavity, wherein the first dielectric/air interface interacts with the first straight edge wall to approximate a magnetic wall thereby creating an electromagnetic image of the electric field within the first half disk resonator structure and the second dielectric/air interface interacts with the second straight edge wall to approximate a magnetic wall thereby creating an electromagnetic image of the electric field within the second half disk resonator structure.
