摘　　要：本文阐述了新型发卡式谐振器和矩形螺旋形谐振器及其在微带均衡器中的应用,利用上述两种谐振器分别设计了两种微带均衡器单子结构电路,通过仿真发现采用新型发卡式谐振器的均衡器单子结构电路具有频率调谐功能;而采用螺旋形谐振器的均衡器单子结构电路不仅具有频率调谐功能,而且具有衰减幅度调节功能,解决了由于实际加工误差引起的频率和衰减偏移问题。最后根据实际需要采用这种螺旋形谐振器设计了一个微带均衡器并给出了其频率曲线。A rectangular spiral microstrip resonator and a miniaturized hairpin resonator are proposed for use in microstrip planar equalizer respectively. The whole circuit area of the proposed resonators are smaller than the conventional resonators. A high frequency structure simulator is used to show that these two compact resonators are suitable to realize microstrip planar equalizer. Simulated results indicate that the equalizer with hairpin resonator can be frequency tunable; and the equalizer with spiral resonator not only can be frequency tunable but also can be attenuation tunable, this can solve the frequency and attenuation offset during the fabrication. At last, a microstrip equalizer composed of this spiral resonator is designed and analyzed, the experiment results are also given in the paper.
