基于多模谐振器的三通带滤波器的设计
Design of a tri-band bandpass filter based on a multiple-mode resonator
摘要
Abstract
An improved tri-band bandpass filter (BPF) using a novel multiple-mode resonator (MMR) was presented. The MMR was constructed by loading two open stubs in a quad-mode resonator (QMR) to generate six transmission poles. Based on the proposed MMR, a tri-band BPF with center frequencies of 2.55, 3.83, and 6.00 GHz was designed, fabricated and experimentally validated. The measurements show a low insertion loss of 0.9, 0.7 and 2.3 dB at each resonant frequency, and have a good agreement with the simulation results. When compared with previous published work, the proposed filter also has advantages such as low return losses and compact size. This tri-band BPF is expected to be used for modern wireless and mobile communications.关键词
