Hi, Bill, Doug Smith, and SI-LIST, Thanks for your reply. i meant the radiation from PCB edge. For example, we can use several techniques such as an edge termination or ring. Could you please recommend any paper or document which includes a designguide and its effect when using the technique such as the edge termination. Is it really helpful for reducing the radiation from PCB edge? If then, how is the designguide? rgs, Jongbae.
