Abstract

ABSTRACT A novel compact ultrawideband (UWB) filter with reconfigurable band notch property is presented. Stepped impedance slotline (SISL) resonator along with two open-ended coupled microstrip is used for the realisation of UWB filter. The WLAN band of rejection is obtained by placing the U-shaped DGS near the SISL resonator. Furthermore, two capacitors are placed in the active slot of U-shaped DGS to obtain WiMAX band of rejection. The proposed UWB filter with reconfigurable band notched characteristics is fabricated and measured. The measured results agree well with the simulated results.

具有可重构带阻特性的紧凑型超宽带滤波器

摘要提出了一种具有可重构陷波特性的紧凑型超宽带滤波器。采用阶跃阻抗槽线（SISL）谐振器和两个开口耦合微带来实现UWB滤波器。通过将U形DGS放置在SISL谐振器附近来获得WLAN的抑制频带。此外，在U形DGS的有源槽中放置两个电容器以获得WiMAX抑制频带。制作并测试了所提出的具有可重构带陷特性的超宽带滤波器。测量结果与模拟结果吻合良好。
