Abstract :
The mechanism of the radiation from a shielded cable caused by the pigtail effect is studied. Usually, both differential mode and common mode current in the cable could produce radiation, but the latter is the dominant contributor. It is observed that the radiation is produced mainly by common mode current driven by the pigtail effect along the outer conductor of the cable. The mathematical model of the common mode and its radiation are presented and discussed based on transmission line and antenna theory. The results of theoretical computation and experimental measurement for the model are presented and shown to be in good agreement.<>
