Cylindrical cavity resonator modes
WebTitle: Microsoft Word - Design of a Cylindrical Cavity Resonator for Measurements of Electrical Properties of Dielectric Materials Author: Xiang WebA cavity resonator is a space surrounded by a rectangular- or cylindrical-shape metal conductor that can confine electromagnetic waves (RF waves) by reflecting them back and forth between the cavity's boundaries. The cavity is excited by a coaxial cable carrying signals from a network analyzer.

WebA DR partially enclosed within a rectangular cavity excited with a vertical monopole is examined. The structure can act as an antenna with several close radiating modes. The example considered has a dual-band characteristic, where a coupling screw is shown to significantly improve its -10dB radiation bandwidth. 展开 WebThe mode matching method is used to accurately model a generalized cylindrical dielectric resonator structure in a rectangular waveguide or cavity. The field distributions of different modes in cavities are given. The resonant frequencies of the cavities are calculated and compared to the measured data, showing very good agreement. The resonator …
