Paper Abstract

Dependence of coupling coefficient between dielectric resonator (DR) and rectangular waveguide versus geometrical parameters and permittivity of material is discussed in this paper. The coupling coefficient was estimated in terms of scattering matrix approximation calculated by finite element method. The method of improvement of dielectric resonator coupling with rectangular waveguide is proposed. Such effect was achieved by insertion of dielectric discontinuity perpendicular to DR's electrical field. It results in increasing of attenuation in band–stop filters and decreasing of insertion loss in band-pass filters. Thermal stabilization method for resonant frequency of composite dielectric resonator is discussed.
