Abstract

The invention relates to a microwave resonant cavity provided with an inner conductor with a helical notch groove structure, belonging to the radio frequency and microwave passive system technical field; the invention comprises an outer conductor cavity, a capacitance loading disc and an inner conductor, wherein the inner conductor which is provided with a notch groove has one end connected with the wall of the outer conductor cavity and the other end connected with the capacitance loading disc which is in parallel to an top cover of the outer conductor cavity; a metal turning plug can be inserted in the outer conductor cavity. The microwave resonant cavity adopts the structure of the inner conductor provided with the notch groove, which makes the resonance frequency of the microwave resonant cavity halved compared with other microwave resonant cavities which are the same in size; thus an aim of greatly reducing the volume of the resonant cavity is achieved.

Description

technical field [0001] The invention relates to a microwave resonant cavity in the field of microwave technology, which is a microwave resonant cavity with an internal conductor of a spiral groove structure. Background technique [0002] Microwave resonators are widely used in the field of microwave technology, and are often used in microwave filters and duplexers as frequency-selective components. There are many types of microwave resonators, and the typical structural types include rectangular waveguide resonators, circular waveguide resonators, coaxial resonators, microstrip resonators and various dielectric resonators. The resonant frequencies of such cavities are determined by their geometric dimensions, boundary conditions and material properties, and the resonant frequencies correspond to the corresponding eigenmodes. Among them, the metal waveguide resonator has a high Q value and a large power capacity, and is often used to design various filters or duplexers with ...
