Abstract

UWB filter is a key device in UWB communication system, which determines the overall performance of the system. The invention relates to a microstrip ultra-wideband band-pass filter, which is based on a novel multi-twig multi-mode resonator. It is characterized in that: the middle of the short-circuit transmission line section (33) is short-circuited through the first metallized through hole (34), and the two ends of the short-circuit transmission line section (33) are connected with the two ends of the transmission line section (32) to form a closed loop; the first open circuit Transmission line section (31), second open transmission line section (35), third open transmission line section (36), fourth open transmission line section (37), fifth open transmission line section (38) and sixth open transmission line section (39) Connected to the transmission line sections (32) respectively, they form a multi-stub multi-mode resonator. 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 band-pass filter based on a novel multi-node multi-mode 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 based on a n...
