Waveguide-dielectric resonator at 28–38 GHz

Calculation data of resonance frequencies and eigen Q-factors of a fundamental electromagnetic oscillation of magnetic type in a waveguide-dielectric resonator (WDR) for millimeter wave band are presented. On the basis of carried out calculations WDR has been designed at frequency range 28-38 GHz and its parameters were measured.

Measurement of parameters of dielectric materials on characteristics of waveguide dielectric resonator

A method of parameters measurement of dielectric materials based on resonance characteristics of a structure which consists of a cylindrical evanescent waveguide partially filled with dielectric element has been considered. Using the expressions associated with the resonance characteristics of the resonator the permittivity and the loss tangent of a dielectric for the dielectric element made of Teflon have been obtained.

Q-factors of a waveguide dielectric resonator with two-layer dielectric on the H/sub on/spl delta// modes oscillations types

Waveguide-dielectric resonators (WDR) are widely used to create active and passive components and devices in the microwave band. The resonance properties of the WDR with a two-layer dielectric element (DE) have been investigated previously. This paper is devoted to the study of the unloaded and partial Q-factors of the resonator built around an evanescent circular waveguide for the axial-symmetrical H/sub on/spl delta// oscillation types.

Dielectric parameters measurement with waveguide-dielectric resonator

The method of low loss dielectric parameters measurement using microwave resonator was suggested. For these measurements the main E/sub 011/ oscillation from axial-symmetrical oscillations class of waveguide-dielectric resonator was used. The measuring section used a circular waveguide part with partial dielectric filling of its cross-section.
