Size of loop area on PCB

[osmanpasali]

i designed a PCB and there is a loop whose dimensions are approximately 5X10 cm. it is a DC current flowing on the loop. does cause a problem from EMC point of view and at which stage of the tests it is a problem?

Unless you are sure there is no clocking single leaks onto the loop otherwise emc may have problem.

According to CE en55022 requirment, emc test on both emission and immunity must compliant. I think you better check this issue.
