Abstract:
A method for reducing EM radiation comprises at least one first resonance line disposed on one of electric surfaces, which is disposed at a side of a transmission line structure on one of the electric surface. The resonance line crosses over a slot of another electric surface. The slot is etched on a corresponding electric surface. In addition, the transmission line structure crosses over the slot of the electric surface. Then, the first resonance line connects the electric surface having the slot with another electric surface. It can adjust at least one of a length, a width and a shape of the first resonance line, to make an input impedance seen from a crossed point between the transmission line structure and the slot approximately 0.
