Abstract

The present invention discloses a tunable substrate integrated waveguide circular resonant cavity filter. A symmetric circular SIW resonant cavity structure is used as a basic unit, and the middle dielectric substrate of the circular SIW resonant cavity structure is provided with an air slot in the diameter direction of the middle dielectric substrate. The air slot is internally provided with a metal column capable of moving along the diameter direction of the middle dielectric substrate, and a turning unit is formed by the air slot and the metal column. The main mold resonance frequency of the circular SIW resonant cavity structure is adjusted through adjusting the circle center distance between the metal column and the middle dielectric substrate. The filter provided by the invention has the advantages of simple structure and easy processing, a frequency band is in a Ku band, the tuning range of the filter reaches 18%, the main mold frequency can be adjusted continuously, and the estimated tuning can be carried out.

Description

technical field [0001] The invention relates to a tunable substrate integrated waveguide circular resonant cavity filter, which belongs to millimeter wave technology. Background technique [0002] With the rapid development of modern microwave and millimeter wave circuit systems, its functions are becoming more and more complex, and its electrical performance requirements are getting higher and higher. At the same time, its volume is getting smaller and lighter; Lightweight, high reliability, versatility and low cost direction. Low-cost, high-performance, high-yield microwave and millimeter wave technologies are critical to the development of commercial low-cost microwave and millimeter wave broadband systems. Therefore, there is an urgent need to develop new microwave and millimeter wave integration technologies. Substrate Integrated Waveguide (Substrate Integrated Waveguide, SIW) is a three-dimensional periodic structure, which can be fabricated in an integrated process,...
