Radiant Microwave Filter for Telecommunications using High Qu Dielectric Resonator

A dielectric resonator device is proposed for high-speed data communication systems. The structure is composed of a partially metallized dielectric plate enclosed in a parallelepipedic cavity. This topology allows a high integration in a planar environment type. This structure, easily manufactured, is suitable for high frequencies filtering and powers applications. In order to realize some radiant n-pole filters without tuning, an opened two-pole filter using two superposed cavities coupled by a metallic iris is presented. Its filtering and radiation functions are optimized in the same time to present some required electrical performances.
