Abstract
Structure of a new type cavity of rectangular shape with a central metallic core is considered. The influence of internal dimensions (core radius) on the eigenfrequencies and the eigenfunctions of electromagnetic field of the two lowest H- and E-modes of such concentric resonator are determined with the help of the finite element method. Moreover parameters of scattering matrix of rectangular concentric resonator with coaxial input and output ports are investigated for the Ka-band. Possibility of realization of small-sized bandpass filter on its basis is shown. Factors influencing on the reflection coefficient in the pass band are analyzed.
