Abstract
A multi-mode cavity filter having a dielectric resonator body incorporating a piece of dielectric material, the piece of dielectric material having a shape such that it can support at least two substantially degenerate resonant modes; and a coupling structure comprising a plurality of independent coupling elements for coupling signals to the piece of dielectric material.
Claims17
A multi-mode cavity filter comprising:
- a dielectric resonator body incorporating a piece of dielectric material, the piece of dielectric material having a shape supporting at least two substantially degenerate resonant modes and one face having a surface;
- and
- a coupling structure on said surface of said one face, said coupling structure including a first plurality of independent coupling elements arranged to couple input signals into the piece of dielectric material and a second plurality of independent coupling elements arranged to recover output signals from the piece of dielectric material, wherein the first plurality of independent coupling elements is distinct from the second plurality of independent coupling elements.
A method of manufacturing a multi-mode cavity filter, the method comprising:
- providing a dielectric resonator body incorporating a piece of dielectric material, the piece of dielectric material having a shape supporting at least two substantially degenerate resonant modes and one face having a surface;
- and
- providing a coupling structure on said surface of said one face, said coupling structure including a first plurality of coupling elements arranged to couple input signals into the piece of dielectric material and a second plurality of independent coupling elements arranged to recover output signals from the piece of dielectric material, wherein the first plurality of independent coupling elements is distinct from the second plurality of independent coupling elements.
