Abstract

The invention discloses a high-performance balance band-pass filter based on equilateral triangle patches. The high-performance balance band-pass filter comprises a layer of dielectric substrate, wherein a first triangular patch, a second triangular patch, a third triangular patch, a fourth triangular patch, a fifth triangular patch, a sixth triangular patch, a first input port feeder line, a second input port feeder line, a first output port feeder line, a second output port feeder line, a top layer first slot line, a top layer second slot line, a top layer third slot line, a top layer fourth slot line, a top layer fifth slot line and a top layer sixth slot line are arranged on the upper surface of the dielectric substrate, and the bottom layer of the dielectric substrate is a grounding metal plate. According to the invention, the balance band-pass filter is simple in structure, can be realized on a single PCB, and is convenient to process and integrate; and six compact triangular patches are adopted, the circuit space is fully utilized, and the circuit size is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of microwave passive devices, in particular to a high-performance balanced bandpass filter based on an equilateral triangular patch. Background technique [0002] Modern wireless communication systems require compact and high performance balanced bandpass filters. In recent years, filters have played a key role in the selection and filtering of signals in wireless communication systems, and because many radio frequency devices have strong robustness to electromagnetic interference and common-mode noise, they need the introduction of balance functions, so The integration of balancing and bandpass filtering can greatly reduce the number of microwave components used in the same system. At the same time, with the continuous development of modern wireless communication systems, the requirements for the performance and integration of band-pass balanced filter devices have also been increased.
