Abstract
A sensor of movement based on a biconical coaxial microwave resonator is considered. Electrical field structure and basic electrodynamics parameters of the biconical coaxial microwave cavity have been calculated with finite element method. The influence of various technological defects and geometrical parameters of the biconical coaxial on the sensor properties has been investigated. It has been determined that form variation and transversal displacement of the internal conductive rod of the resonator have produced maximal influence on the sensor parameters.
