The invention solves the problem of very small radiation field in outer space of antenna as the current space flow direction in the existing antenna after the antenna is folded is opposite to that before the antenna is folded. Both a first coaxial line (1) and a second coaxial line (2) in the invention has one end bended into 90 degrees, the bending end of the first coaxial line (1) is arranged opposite to the bending end of the second coaxial line (2), a first copper core (1-1) of the first coaxial line (1) is connected with a second outer sheath (2-3) of the second coaxial line (2), and a first outer sheath (1-3) of the first coaxial line (1) is connected with a second copper core (2-1) of the second coaxial line (2). In the invention, the current flow directions of the outer sheath of coaxial line are the same by the misconnection of two coaxial lines so that the radiation field in outer space of antenna is increased, thereby solving the problems of very small radiation field in outer space of antenna as the current flow directions thereon after coaxial lines are folded directly are opposite.
