| 摘 要： | 本文基于复合左右手传输线理论提出了一种设计超宽带滤波器的新方法。该方法从传输的幅度和相位出发，利用微带线结构构建复合左右手传输线，通过控制复合传输线的左手响应频率和右手响应频率来构建微波带通结构。通过在微带线上采用缺陷地板结构物理上实现负等效介电常数，得到低通特性；采用微带线加载交指电容实现负等效磁导率，得到高通特性。最终通过将两种情况组合，构建具有较强左手特性和较弱右手特性的复合传输线，完成基于微带线结构的超宽带滤波器设计。文中给出的仿真结果和实测结果吻合良好，有利的证明了该方法的有效性和实用性。

| Abstract: | A novel design method of ultra-wide band(UWB) filter based on the composite right/left-handed transmission line(TL) theory is presented.According to amplitude and phase of transmission,a composite right/left handed transmission line is fabricated based on microstrip structure,and microwave band-pass structure is constructed through controlling left handed and right-handed response frequency of the composite transmission line.To achieve low-pass characteristic through obtaining negative equivalent permittivi... |
