[0017] Laying first radiator 3 and second radiator 4 on PCB board 1 realizes the antenna effect of 3300MHz~5GHz, and the PCB board 1 can use the plate structure of conventional shape, which is convenient for assembly on the equipment machine, so that the antenna assembly is simple and not complicated when the production line assembly machine. First radiator 3 and second radiator 4 adopt the structure form of the dipole, and the efficiency and gain of the antenna are improved. The gap groove is symmetrically arranged on first radiator 3 and second radiator 4 to adjust the impedance of the antenna, so that the impedance of the antenna is closer to 50 ohms, and the performance is more excellent. The feed point 5 on first radiator 3 and second radiator 4 is used for connecting radio frequency cable line, to realize the transmission of antenna signal.
