✦ Synopsis
A dielectric resonator filter is proposed for high-speed data communication systems and for multilayer filter applications. The structure is composed of a partially metallized dielectric plate enclosed in a parallelepipedic cavity. This topology allows high integration in a planar-type environment. The proper excitation is ensured by coplanar lines directly integrated on the dielectric resonator. This structure, easily manufactured, is suitable for high frequency-filtering and power applications. In order to realize two-and four-pole filters without tuning, some new coupling and frequency compensation techniques are presented. To compensate for a parasitic effect, a direct optimization method is ( ) combined applying a global electromagnetic EM analysis to describe the four-pole filter. Some experiments are performed to verify the theoretical design.
