摘要
滤波器寄生通带对带外抑制会产生非常严重的影响,甚至使得滤波器无法正常工作。结合基片集成波导结构(SIW)结构,设计出一种宽阻带的滤波器。仿真和实验吻合良好。该滤波器具有重量轻、工作频率高、便于集成等优点。
Additional pass band plays a deteriorative role in skirt selectivity. A novel approach for SIW （Substrate Integrated Waveguide） filter without additional TE102 pass band is introduced. The theory result agrees well with the measured results.
