Disk dielectric resonators (DR) with the azimuthal modes made of materials with small losses have found application in millimeter and centimeter wavelengths. The Q-factor of these resonators is determined by the heat losses in the dielectric and the radiation losses. Constructively, resonators can be performed both in the open and shielded versions.

The paper presents the results of studies of the characteristics of plate dielectric resonators made from sapphire and crystall quartz. These materials are uniaxial crystals and have low thermal losses in the millimeter wavelength range. Resonators on the basis of two coaxially located disks with the orientation of the anisotropy axis of materials in the direction of the geometric axis of the axisymmetric structure are considered. Excitation of resonators is made on modes with a predominant orientation of the electric field along the axis of the axisymmetric structure - НЕn,1,1. It is shown that the increase in the Q-factor of plate DR from sapphire and crystal quartz relative to the Q-factor of single DR can reach (15-20)%.
