Abstract :
A new dual mode coupling technique is described. This new method replaces the classical coupling and tuning screws by slotted dielectric resonators. The theoretical analysis uses the three-dimensional finite element method. For the first time, a four-pole dual mode slotted dielectric resonator filter is rigorously designed, taking into account the dielectric losses. The experimental results show excellent agreement with the theoretical ones.<>
