Abstract

UWB filter is a key device in UWB communication system, and its performance determines the overall performance of the system. The invention relates to a microstrip ultra-broadband bandpass filter, which is based on a novel king-shaped multimode resonator, and is characterized in that: the first open-circuit transmission line section (31) and the second open-circuit transmission line section (36) are respectively connected To the first parallel coupling line section (32), one end of the first parallel coupling line section (32) is connected to the third open transmission line section (33), and the other end of the first parallel coupling line section (32) is connected to the second parallel coupling line section (34) and a third parallel coupled line section (35). Research shows that the ultra-wideband bandpass filter of the present invention has the advantages of high performance and miniaturization.

Description

technical field [0001] The invention belongs to the technical field of ultra-wideband communication, and in particular relates to a microstrip ultra-wideband bandpass filter based on a novel king-shaped multimode resonator. Background technique [0002] In 2002, the Federal Communications Commission (FCC) of the United States opened the frequency band between 3.1 GHz and 10.6 GHz for applications in the communication field. Because of its advantages such as high transmission rate and low transmission loss, UWB communication has received extensive attention and developed rapidly. As a key device in an ultra-wideband communication system, the performance of the ultra-wideband bandpass filter determines the overall performance of the system. However, designing small, high-performance, and low-cost filters remains a major challenge. Contents of the invention [0003] The object of the present invention is to provide a microstrip ultra-wide band band-pass filter in order to o...
