摘　　要：基于非对称耦合馈线结构,设计了一种通带内具有单阻带特性的超宽带滤波器.通过调节非对称耦合馈线结构的物理尺寸,能够控制超宽带通带内阻带频率的位置,从而有效减少其他频段的干扰.利用ADS仿真软件对研究设计的超宽带滤波器进行仿真计算,仿真结果表明该滤波器不仅具有良好的通带效果,还具有阻带位置灵活可调的优良特性.In this paper, an ultra-wideband（UWB） filter with single stop band characteristics in a passband is proposed based on asymmetric coupled lines. By properly adjusting the physical dimensions of the asym- metric coupled lines, a stop band frequency in the passband of the ultra-wideband can be controlled to ef- fectively reduce the interference of other frequency bands. The simulating calculation is done on the ultra wide-band filter designed by using ADS. The simulation results show that the proposed filter exhibits good in-band performances. In addition, the location of the stop band can be easily adjusted because of its flexi- ble position.
