In this paper, a new design of reconfigurable stop-band in UWB band-pass filter based on resonator-loaded slot-line is presented and implemented. The obtained stop-band response is performed by embedding a single PIN diode in the resonator. When the PIN diode state is OFF, a UWB response is achieved. Nevertheless, when the diode is in ON, a notch is created in the UWB filter. In addition, the obtained notch-band could be adjusted by modifying the length of the microstrip resonator-loaded slot-line. Then, a stop-band, created at 5.8 GHz for wireless communication (WIFI), is designed. The obtained results show that insertion loss is less than 0.3 dB, return loss is greater than 14 dB and the group delay is 0.23 ns at the entire UWB band.

在本文中，提出并实现了一种基于谐振器加载槽线的 UWB 带通滤波器中可​​重构阻带的新设计。通过在谐振器中嵌入单个 PIN 二极管来执行获得的阻带响应。当 PIN 二极管状态为 OFF 时，实现 UWB 响应。然而，当二极管处于导通状态时，会在 UWB 滤波器中产生一个陷波。此外，可以通过修改微带谐振器加载槽线的长度来调整获得的陷波带。然后，设计了一个在 5.8 GHz 下创建的用于无线通信 (WIFI) 的阻带。得到的结果表明，在整个UWB频段，插入损耗小于0.3 dB，回波损耗大于14 dB，群时延为0.23 ns。
