摘要
辫接导线引起的电磁泄露,是屏蔽视频电缆泄漏最严重的部分。利用广义二端口网络法和天线理论求解视频电缆的辐射:从理论上分析了产生这种结果的原因,并提出减少这种辐射的方法,该方法对辫接效应的抑制大于20dB。
The leakage of a shielded video cable caused by the pigtail is the most serious.In this paper,calucations of theradiation are introduced on the basis of the generalized two-port network method and antenna theory.Finally,the reason forproducing this effect is discussed theoretically,and certain protective methods and techniques are presented,which exhibit atleast 20-dB suppressions against the pigtail effect.
