Losses of the parallel-plate dielectric resonator

The various loss aspects of the parallel-plate microwave dielectric resonator for the TE_01delta mode is studied from a modified field model. The main merit of this field model is that it provides very simple electromagnetic field expressions of this field mode. Various methods of calculation of losses are discussed. The analyses of the calculated results of conductor and radiation losses are given. The relationship of the loss with the dimensions of the device is introduced. By conducting practical measurements to compare with theoretical calculation results, this modified model has shown dramatic improvement over the unmodified model. The dielectric loss measurement by using this parallel-plate dielectric resonator is also studied.
