Abstract

The present invention relates to an adjustable filter. The adjustable filter comprises: a first dielectric substrate; a second dielectric substrate which is arranged with the first dielectric substrate at intervals, wherein a third board is opposite to a second board; a first conductive layer arranged on the second board or the third board; a second conductive layer arranged on a fourth board; a conductive perturbation column penetrating the second dielectric substrate and electrically connected with the first conductive layer and the second conductive layer; a metal via hole array, wherein the centers of metal via holes of the metal via hole array are on the same line, each metal via hole of the metal via hole array penetrates the first dielectric substrate, the second dielectric substrate, the first conductive layer and the second dielectric substrate and conducts the first conductive layer and the second conductive layer; and a first regulation device arranged in a range enclosed bythe first conductive layer. The adjustable filter is simple in structure, can effectively reduce the design and production manufacturing cost, achieves the bandwidth adjustment and broadens the bandwidth.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an adjustable filter. Background technique [0002] In recent years, with the rapid development of the communication industry, broadband communication systems have been widely used, and the bandwidth selectivity and utilization of frequency resources of the broadband communication system have become more and more important. Therefore, how to solve the problems of bandwidth selectivity and utilization of frequency resources in broadband communication systems has also attracted the attention of researchers. [0003] Filter is an important part in broadband communication system, and improving its performance plays a very important role in improving the performance of broadband communication system. In recent years, with the continuous improvement of design ideas, filters such as dual-mode resonance and step impedance resonance have appeared. [0004] However, during the impl...
