【摘要】 本文基于悬置微带线间隙不连续性的严格分析,导出了计及色散效应的不连续性等效电路参量。应用宽带网络综合理论,给出了端部耦合的悬置微带线带通滤波器的精确设计方法。根据这一方法,设计和试制了两个不同带宽的Ka波段带通滤波器样品,实验测得滤波器的带内最小插入衰减分别为1.42dB和1.01dB。更多还原

【Abstract】 Based on the rigorous analysis of the gap discontinuity in a suspended stripline, the frequency-dependent parameters of equivalent network are obtained. An accurate design method for millimeter wave suspended stripline end-coupled bandpass filters is presented by the use of wideband network synthesis theory. Two Ka-band bandpass filter samples with different bandwidth are designed and fabricated with this method. The measured minimum insertion losses in the bandpass are 1.42dB and 1.01dB, respectively.更多还原
