摘要
提出了一个利用三截面阶梯阻抗谐振器(SIR)的微带双通带滤波器,两个通带的中心工作频率分别为2.4 GHz和5.2 GHz。由二截面SIR的谐振特性可看出,采用三截面SIR不仅比二截面SIR设计自由度更大,有利于滤波器的设计和减小滤波器所占用的电路面积。该文分别从仿真和测试两方面对该滤波器进行了研究,设计结果显示所设计的双通带滤波器结构紧凑,且仿真和测试结果吻合很好。
A microstrip dual-band filter using tri-section stepped impedance resonator（SIR） is presented in this paper.Center frequencies of two passbands are located at 2.4 GHz and 5.2 GHz,respectively.Tri-section SIR has not only more designs freedom but also occupies less circuit area compared with resonant characters of two-section SIR.Simulation and measurement are carried out in this paper to investigate the filter.Design results show that the filter has compact structure,and the simulated and measured results are agreed with very well.
