DUAL POLARIZATION DIPOLE ANTENNA INCLUDING BALUN BASED ON A PRINTED CIRCUIT BOARD TO REDUCE A DISTORTION SIGNAL

摘要

PURPOSE: A dual polarization dipole antenna including balun based on a printed circuit board is provided to reduce the size of the antenna.;CONSTITUTION: A first dipole(11) is printed with copper foil on one side of a printed circuit board(10). A second dipole(12) is printed with copper foil in the vertical direction of the first dipole. A connecting part(15) is formed with rectangular copper foil in the overlapped area of the second dipole and the first dipole. The first feed wire(20) is connected to the end of the first dipole. The second feed wire(21) is connected to the end of the second dipole. A core hole passes through the upper and the lower part of the printed circuit board to transmit power feed signal to the first feed wire and the second feed wire. An air bridge prevents the intersection of the second feed wire and the first feed wire.;COPYRIGHT KIPO 2013
