Abstract: This invention relates to a board-shaped wideband dual polarization antenna whose feeding structure is simplified. Dipole antennas are prepared on both front and rear surfaces of a printed circuit board, and an electric signal is fed to the dipole antennas through via holes at the same time. Through the dipole antennas, the dual polarization antenna radiates dual polarized waves whose radiation emissions have perpendicular directions to each other. The wideband characteristics of the dual polarization antenna are improved through parasitic elements. The disclosed printed circuit board comprises: a first line hole into which a first core line (+) of a first electric cable transmitting a first electric signal is inserted; a first ground via hole through which a first ground line (−) of the first electric cable passes; a first balun hole into which a first balun cable is inserted; a second line hole into which a second core line (+) of a second electric line is inserted; is second balun hole into which a second balun cable is inserted; and a connection via-hole through which both the second core line (+) and the second balun cable pass. The first and second balun cables make a pair with the first and second electric cables respectively by being parallel to those electric cables respectively in order so perform the function of a balun. According to the invention, the dual polarization antenna is able to radiate, through the dipole antennas on both surfaces of the printed circuit boards, dual polarized waves whose radiation emissions have perpendicular directions to each other. In addition, the feeding structure can be simplified and a complex three-dimensional air-bridge structure does not need to be used in the dual polarization antenna since an electric signal is fed to the dipole antennas on both surfaces of the printed circuit board at the same time.
