摘要
The present invention relates to a balun integrated printed circuit board-based dual polarization dipole antenna, and a balun on a substrate to form a dual polarized dipole and the connecting member is to improve the electrical characteristics of the structure and the propagation of the antenna. The dual polarization dipole antenna according to the present invention includes a first dual polarization dipole antenna formed on one surface of the printed circuit board and the printed circuit board. Wherein the first dipole comprises a second dipole, ground, the first power supply line, a second power supply line, core line hole and the connecting member. The first dipole is to form the matching circuit of the tapered width is gradually decreased at both ends of the U balun is formed, the copper foil is printed on one side of the printed circuit board. The second dipole is in the form of the first dipole and is printed on the copper foil 90 in the axial rotational movement of the position of the center of the printed circuit board with respect to the longitudinal direction of the first dipole. Grounding the first dipole and a second dipole portion is a copper foil having a rectangular shape is formed at the center of overlapping. The first power supply line is formed on one surface of a copper foil line connecting the end of the first dipole the printed wiring board. A second power supply line is a line connecting the ends of the second copper foil dipole, the first power supply line and the center to both ends to form a close-up, at least one via hole is formed at the opposite ends. Core line hole of the printed circuit board to insert the cable for transmitting the power supply signal to the first power supply line and the second power supply line, is formed into a penetration of the lower surface. And the connecting member is electrically connected to both ends of the second feed line. ;
