The present invention provides a folded dipole antenna capable of transmitting and receiving signals from a CDMA 450 system. A folded dipole antenna is a folded dipole printed circuit board (PCB) having conductive strips defined on each side of a folded dipole printed circuit board (PCB) forming an excitation arm and a grounding arm of the antenna , Both the arm and the ground arm are configured symmetrically with the conductive strip configuration, and the conductive strip on each side of the PCB includes an m-shaped conductive strip having a central conductive leg and two symmetrically folded arms, Wherein the legs are thinner than the two folded arms, the folded dipole antenna printed circuit board; A plastic holder, wherein a folded dipole PCB is disposed therethrough; A base plate, wherein the folded dipole PCB is vertically mounted on a base plate through a plastic holder; And a metal core brazed along the central conductive leg of the grounding arm, the central core extending through the folded dipole PCB to connect with the arm at one end, and the other end of the coaxial cable extending through the base plate , And the coaxial cable.
