This paper described a designing method of a new structure microwave dielectric filter. The relation of the coupling structure and resonating structure in the filter was analyzed , the structure parameters computed by the microwave net theory were simulated and optimized by advanced EDA tool （HFSS） and a ideal result could be acquired. According to the simulated and optimized results , the microwave dielectric filters were fabricated and their final properties was consistent with the designing request.
