Abstract :
The paper discusses radiated emission at the far zones from PCB circuits, which can be treated as equivalent transmission lines. The differential-mode and common-mode current distributions are analysed by means of a transmission line approach. Then, with the assistance of line antenna theory, the radiated emission produced by these currents are calculated. Finally, computational results are given and compared with experimental results
