Abstract

A triple-band bandpass filter with good selectivity based on asymmetric square ring loaded resonator (ASRLR) is proposed in this paper. The even- and odd-mode method is applied to investigate the resonant characteristic of the proposed triple-mode ASRLR. The 50-Ω tapped line is applied to design the I/O ports. The operating bands of the designed tri-band BPF are located at 1.57 GHz (GPS application), 3.5 GHz (WiMAX application) and 5.2 GHz (WLAN application), respectively. To verify the proposed approach, the filter is designed and analyzed by using EM simulator, the obtained results are agree well with the theory analysis?

紧凑的三带带通滤波器，采用非对称方形环负载谐振器

提出了一种基于非对称方环负载谐振器(ASRLR)的三频带带通滤波器，具有良好的选择性。采用奇偶模方法研究了三模ASRLR的谐振特性。采用50-Ω抽头线设计I/O口。所设计的三频段BPF的工作频段分别位于1.57 GHz (GPS应用)、3.5 GHz (WiMAX应用)和5.2 GHz (WLAN应用)。为了验证所提出的方法，利用仿真器对滤波器进行了设计和分析，得到的结果与理论分析吻合较好。
