First Claim
Patent Images
1. A dielectric resonator comprising dielectric member, the geometry of said member corresponding to a body with a section removed therefrom, said body being generally symmetrical about an axis and said section being defined by two planes which intersect along said axis and form an angle greater than 0 degrees.

Abstract
A dielectric resonator has a sector shape, and a filter has a signal source for emitting signal to be filtered, signal receiver for receiving the filtered signal and a path defined between the signal source and the signal receiver. At least one sector shaped dielectric resonator is disposed in the path.
