Abstract
Disclosed is a printed circuit board, which includes an electromagnetic bandgap structure disposed around an antenna so as to prevent noise from being transmitted to the antenna. The printed circuit board includes an antenna, a circuit chip, a plurality of metal layers and a plurality of dielectric layers, a pair of transmission lines for transmitting a signal to the antenna, and an electromagnetic bandgap structure disposed between the antenna and the circuit chip and for preventing an electromagnetic wave from being transmitted from the circuit chip to the antenna.
