[0025] The utility model takes into account the current ordinary double-vibrator antenna generally can not satisfy higher gain requirement, aiming at this kind of situation, the utility model proposes a kind of multi-vibrator directional PCB antenna, by increasing multiple groups of vibrators on the basis of adding radio frequency line to PCB board, so that the antenna performance can meet the requirement.

[0026] Please refer to Figure 1 And Figure 2 The utility model multi-vibrator directional PCB antenna preferred embodiment includes reflector (not shown in drawing), PCB board 10, at least three groups of vibrators 20, at least two combiners 30 and at least six radio frequency lines 40, the PCB board 10 is arranged on the reflector, the three groups of vibrators 20 are equidistantly arranged on the PCB board 10, the combiner 30 is arranged between adjacent two groups of vibrators 20, and each group of the vibrator 20 is connected to the signal input end of the two combiners 30 by two radio frequency lines 40 respectively.

[0027] In the embodiment, the PCB board 10 is connected with the reflector by buckle 60, so as to facilitate dismounting and mounting.

[0028] The through hole for inserting the combiner 30 is arranged on the PCB board 10, and the combiner 30 is inserted into the through hole and then welded and fixed by the reserved welding point.

[0029] In the embodiment, one end of the radio frequency line 40 is welded on the PCB board 10, and the other end is welded on the signal input end of the combiner 30.
