| Abstract: | The leakage of a shielded video cable caused by the pigtail is the most serious. In this paper, calculations of the radiation are introduced on the basis of the generalized two-port network method and antenna theory. Finally, the reason for producing this effect is discussed theoretically, and certain protective methods and techniques are presented, which exhibit at least 20-dB suppressions against the pigtail effect. |
