| 摘 要： | 基于新型的带开路枝节的双模开环谐振器，设计了应用于无线局域网（WLAN）IEEE 802.11 b/a（2.4/5.2 GHz）的双频带微带滤波器.双模开环谐振器的奇模和偶模谐振频率，分别由开环结构和开路枝节负载激励产生.双频带滤波器由两个双模开环谐振器电磁混合耦合实现，具有4个传输零点.滤波器的两个通带分别由双模谐振器的基频和一次杂散频率产生.为了满足输入和输出阻抗匹配要求，并改善双频段的通带特性，采用锥形渐变线0°馈电方式.双频带滤波器的频率响应特性S11和S21的电磁仿真和实测结果非常吻合，两个通带均呈现很好的通带特性和隔离效果.

| Abstract: | Based on a new open-stub loaded dual-mode open-loop resonator,a dual-band microstrip filter is designed for applications of wireless local area networks(WLAN) IEEE 802.11b/a(2.4/5.2 GHz).The odd-mode and even-mode resonant frequencies of the dual-mode open-loop resonator are created by structures of open-loop and loaded open-stub separately.A dual-band filter is realized by two electrically and magnetically mixed coupling resonators with four transmission zeros.Two passbands of the filter are produced by th... |
