Abstract :
This paper describes a high-Q X-band distributed Bragg resonator that uses an aperiodic arrangement of non-??/4 low loss alumina plates mounted in a cylindrical waveguide. An ABCD parameter waveguide model was developed to simulate and optimize the cavity. The dielectric plates and air waveguide dimensions were optimized to achieve maximum quality factor by redistributing the energy loss within the cavity. An unloaded quality factor (Q0) of 196 000 was demonstrated at 9.93 GHz.
