摘　　要：研究并制作了一种基于左手传输线的带通滤波器。同传统的耦合带线和发卡型带通滤波器相比,左手传输线带通滤波器具有尺寸小、损耗小、相位常数大且可调整等优点。给出了实验样品和实测数据,结果表明实际测试与理论预计吻合得很好。A novel band-pass filter, consisting of left-handed microstrip line, has been developed and measured. Comparing with the traditional coupled-line band-pass filter and hairpin filter, the new structure has shown some inherent advantages, such as compactness and low loss, because the larger and adjustable phase constant of the left hand transmission line.
