Abstract
A plural circuit filter for electromagnetic waves, especially microwaves, of the type which comprises dielectric resonators, is provided wherein dielectric resonator disks or washers are positioned in a tubular metallic housing acting as a shield, the resonator disks being positioned centrally of the housing tube with the axes of the disks extending perpendicularly to the axis of the tube and the separate resonator disks being separated in the housing by apertured partitions which partly determine the coupling coefficient between adjacent circuits.
