Abstract

The invention discloses a broadband miniaturized substrate-integrated coaxial voltage-controlled resonator comprising a first metal layer, a first dielectric layer, a second metal layer, a second dielectric layer, a third layer, a third dielectric layer and a fourth metal layer that are laminated successively from top to bottom. According to the invention, the broad tuning function for the resonant frequency is realized. Compared with the same microstrip substrate-integrated waveguide structure, the structure of the provided resonator is miniaturized, so that the possibility of wide tuning andminiaturization of a filter or oscillator based on the substrate-integrated coaxial voltage-controlled resonator is increased.

Description

technical field [0001] The invention relates to microwave and millimeter wave passive devices, in particular to a broadband miniaturized substrate integrated coaxial voltage-controlled resonator. Background technique [0002] With the rapid development of millimeter-wave circuits and systems, their functions are becoming more and more complex, and the requirements for electrical performance indicators are getting higher and higher. At the same time, they are also required to be smaller and lighter in size; Lightweight, broadband, and low-cost development. Among them, the miniaturization and broadbandization of microwave and millimeter wave systems are based on the miniaturization and broadbandization of individual components. Therefore, the miniaturization and broadbandization of a single microwave device is the key to circuit design. [0003] Resonators are the basic components of microwave circuits, which can be used to design various filters and oscillators. Traditional...
