摘要
发展了一种新型HTS双模多次曲折微带环谐振器滤波器 .给出了双模间耦合系数的精确计算方法 .采用全波技术对四极滤波器特性进行的计算表明 ,它具有优良的窄通带、高选择性和小体积 .设计、制造和测试了一个HTS四极滤波器 ,实验结果与理论计算基本一致 .
A new HTS planar microwave filter using dual mode multi zigzag square loop resonators is developed.A method for the accurate calculation of the coupling coefficent between two degenerate modes in this structure is presented.The results of the full wave analysis of the 4 pole filter have shown that the filter has high performance,selectivity,and substantial size reduction.A 4 pole HTS bandpass filter with the bandwidth 1.8% at a central frequancy 1.396 GHz is designed,fabricated and experiment results is good.
