Abstract
A dielectric-loaded cavity resonator has a conductive (e.g., copper) box defining a cavity and a dielectric (e.g., ceramic) resonator mounted within the box. The dielectric resonator has a cylindrical dielectric post and first and second dielectric pedestals respectively connected to the ends of the post and having lateral dimensions greater than the diameter of the post. Insulating (e.g., PTFE) pads are mounted onto outer surfaces of the pedestals to provide air gaps between the pedestals and corresponding top and bottom walls of the box. In certain embodiments, the pedestals have rectilinear, 3D shapes completely or only partially covering the top and bottom walls of the cavity, while, in other embodiments, the pedestals have cylindrical shapes maximally or less than maximally covering the top and bottom walls of the cavity.
