Abstract

The invention discloses a four-mode bandpass filter based on a 1 / 3 equilateral triangular substrate integrated resonator, which includes a resonator cavity, an elliptical metallized through hole and two microstrip lines. The resonator cavity consists of a top metal layer, a dielectric substrate and a bottom metal layer that are parallel to each other from top to bottom. Two microstrip lines are respectively connected to the resonator cavity to form a complete resonator, and the elliptical metallization Vias are provided on the resonator. The invention has the advantages of simple structure, easy processing, large working bandwidth and good electrical performance, and solves the contradiction between the increase of filter frequency range and the difficulty of industrial processing.

Description

technical field [0001] The invention belongs to the technical field of millimeter waves, and in particular relates to a four-mode bandpass filter based on a 1 / 3 equilateral triangular substrate integrated resonator. Background technique [0002] In modern wireless communication, the microwave frequency band communication system has a lot of services, and the frequency resources are extremely tight. Future communication technology is developing towards a higher frequency band—millimeter wave. As a part used to separate signals, a filter is one of the key parts in a wireless communication system. Triangular substrate integrated resonators have the characteristics of high quality factor, low insertion loss, compact structure, high power capacity, etc., and are widely used in modern communications. As the frequency range continues to increase, the size of millimeter wave devices will continue to shrink. When the design size of millimeter-wave devices is reduced to a certain ex...
