[0013] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0014] like Figure 1 As shown, the utility model discloses a directional antenna, including an antenna reflector 1, an antenna vibrator 2, and a radio frequency line 4. The four sides of the antenna reflector 1 are bent so that the antenna reflector 1 forms a box body with an opening. The antenna vibrator 2 is installed in the box body, and there is a gap between the antenna vibrator 2 and the bottom of the antenna reflector 1 in the longitudinal direction. The radio frequency line 4 passes through the bottom of the antenna reflector 1 and is connected to the antenna vibrator 2.

[0015] The antenna element 2 is a radiator that emits signals. The antenna reflector 1 can reflect the signals emitted by the antenna element 2 and can also control the radiation in the reverse direction.

[0016] As a preferred embodiment of the utility model, the directional antenna also includes a support column, one end of which is connected to the bottom of the antenna reflector 1, and the other end of which is connected to the antenna vibrator 2. The length of the support column is 5 mm, and the antenna reflector 1 and the antenna vibrator 2 have a certain gap height through the support of the support column.

[0017] The directional antenna further comprises a screw 3 , and the other end of the support column is fixed to the antenna element 2 via the screw 3 .

[0018] The RF line 4 is welded to the antenna vibrator 2 to form a welding point 5. The antenna vibrator 2 is provided with a plurality of openings 6, and the plurality of openings 6 are located around the welding point 5. There are two RF lines 4. The openings 6 are designed around the welding point 5 to reduce the problem that the aluminum plate material dissipates heat quickly and cannot be welded during welding.

[0019] The antenna element 2 is made of aluminum, and the feed point of the antenna element 2 is designed to be close to the center to control the antenna standing wave to reach the required effect. The height of the antenna element 2 is used to adjust the gain and beam angle of the antenna pattern. The antenna reflector 1 uses four bends to achieve the effect of nearly consistent antenna pattern beams.
