[0030] Please refer to Figures 1 to 5 The utility model provides a split antenna with adjustable direction, including two groups of antenna units 1, a supporting base plate 2, a first supporting plate 3 and a second supporting plate 4, wherein the first supporting plate 3 and the second supporting plate 4 are arranged opposite to each other and are fixedly mounted on the supporting base plate 2, and the first supporting plate 3 is provided with a first arc-shaped rotating groove 31, a second arc-shaped rotating groove 32 and a U-shaped avoiding groove 33; the antenna unit 1 includes a reflecting plate 11, an antenna array unit 12, an adjusting bolt 13, an adjusting linkage assembly 14 and a phase shifter 15;

[0031] The control ends of the adjusting bolt 13 and the adjusting linkage assembly 14 are both arranged at one end of the reflecting plate 11; the adjusting bolt 13 is detachably assembled in the first arc-shaped rotating groove 31 or the second arc-shaped rotating groove 32; the other end of the reflecting plate 11 is rotatably assembled on the second supporting plate 4;

[0032] The phase shifter 15 and the antenna array unit 12 are respectively installed on the reflector 11 , and the phase shifter 15 is connected to the antenna array unit 12 . The control end of the adjustment linkage assembly 14 passes through the U-shaped avoidance groove 33 , and the transmission end of the adjustment linkage assembly 14 is transmission-connected to the phase shifter 15 .

[0033] The split antenna with adjustable direction is provided with two groups of antenna units 1, both of which can realize vertical tilt adjustment by adjusting bolts 13; at the same time, the phase shifter 15 can be adjusted by adjusting the linkage assembly 14 to realize horizontal azimuth adjustment. The two groups of antenna units 1 are independent of each other, and are both provided with adjustment bolts 13, adjustment linkage assembly 14 and phase shifter 15, which can be adjusted separately, and the vertical tilt and horizontal azimuth adjustment operations of the two groups of antenna units 1 will not affect each other; the antenna units 1 are respectively arranged on both sides of the length direction of the supporting base plate 2, and the corresponding antenna units 1 can be adjusted according to actual needs to achieve multi-dimensional coverage, ensure excellent coverage, improve antenna radiation utilization, and ensure the coverage quality of the wireless network.

[0034] When the vertical tilt angle needs to be adjusted, the adjusting bolt 13 can be turned to release the clamping state of the adjusting bolt 13 and the reflector 11 on the first support plate 3; then, the reflector 11 is turned to change the position of the adjusting bolt 13 in the first arc-shaped rotation groove 31 or the second arc-shaped rotation groove 32; since one end of the reflector 11 is detachably assembled in the first arc-shaped rotation groove 31 or the second arc-shaped rotation groove 32 through the adjusting bolt 13, and the other end of the reflector 11 is rotatably assembled in the second support plate 4, the line connecting the two ends of the reflector 11 is the rotation axis. When the reflector 11 is turned, the reflector 11 rotates around the rotation axis to change the vertical tilt angle and realize the vertical tilt angle adjustment. When the angle is appropriate, tighten the adjusting bolt 13 so that the adjusting bolt 13 is tightly against the first support plate 3, and cooperates with the first support plate 3 to achieve the clamping and fixing effect, and fix the reflector 11.

[0035] When the horizontal azimuth angle needs to be adjusted, the control end of the linkage assembly 14 is turned to adjust the transmission end of the linkage assembly 14 to push or pull the toggle plate of the phase shifter 15, thereby controlling the phase shifter 15 to deflect the phase shifter 15, thereby achieving the purpose of adjusting the horizontal azimuth angle.

[0036] The antenna array unit 12 includes a plurality of antenna units, which are arranged at intervals on the upper surface of the reflector 11 to form a row of radiation unit arrays.

[0037] In a specific embodiment of the present invention, the vertical tilt angle of the reflector 11 can be adjusted from -30° to +30°, and the main lobe tilt angle of each column of the radiation unit array can be adjusted from -10° to +10°.

[0038] Specifically, the adjustment linkage assembly 14 includes an adjusting screw 141, a transmission sleeve 142 and a linkage rod 143. One end of the adjusting screw 141 can be rotatably assembled on the U-shaped avoidance groove 33, and the other end of the adjusting screw 141 is rotatably assembled on the reflective plate 11. The transmission sleeve 142 is threadedly connected to the adjusting screw 141, one end of the linkage rod 143 is connected to the adjusting screw 141, and the other end of the linkage rod 143 is transmission-connected to the phase shifter 15.

[0039] The adjusting screw 141 and the transmission sleeve 142 are threadedly connected to form a spiral transmission structure. When the adjusting screw 141 rotates, the transmission sleeve 142 moves linearly along the thread of the adjusting screw 141, thereby realizing linear motion. Since the transmission sleeve 142 and the linkage rod 143 are connected, when the adjusting screw 141 is rotated, the transmission sleeve 142 drives the linkage rod 143 to move along the direction of thread rotation, thereby pushing or pulling the toggle plate of the phase shifter 15 to achieve the purpose of horizontal azimuth adjustment. One end of the adjusting screw 141 assembled on the U-shaped avoidance groove 33 is the control end of the adjusting linkage assembly 14. In a specific embodiment, the control end is connected with a transmission cap. One end of the linkage rod 143 connected to the phase shifter 15 is the transmission end of the adjusting linkage assembly 14.

[0040] Specifically, the adjustment linkage assembly 14 also includes a limit plate 144, a connecting frame 145 and a connecting column 146; the lower end of the connecting column 146 is fixed to the reflective plate 11; the upper end of the connecting column 146 is connected to the limit plate 144; the limit plate 144 is provided with a limit sliding groove 1441; the connecting frame 145 includes a connecting plate 1451 and a guide rod 1452; the connecting plate 1451 is connected to the transmission shaft sleeve 142; one end of the guide rod 1452 is connected to the connecting plate 1451, and the other end of the guide rod 1452 is inserted into the limit sliding groove 1441.

[0041] By adopting the above structure, the sliding range of the transmission sleeve 142 is limited by the limit plate 144 and the connecting frame 145, thereby preventing the transmission sleeve 142 from sliding too far, causing the horizontal movement distance of the linkage rod 143 to be greater than the maximum movable range of the phase shifter 15 toggle plate, thereby avoiding damage to the phase shifter 15.

[0042] The connecting frame 145 is used to connect the transmission sleeve 142 and the guide rod 1452, and the guide rod 1452 is inserted into the limiting sliding groove 1441. When the adjusting screw 141 rotates, the transmission sleeve 142 moves linearly along the thread of the adjusting screw 141, and drives the connecting frame 145 and the guide rod 1452 to move horizontally, so that the guide rod 1452 can slide along the limiting sliding groove 1441, thereby achieving the purpose of limiting.

[0043] Furthermore, the reflective plate 11 is rectangular, and the side of the reflective plate 11 is bent upward to form a skirt 110 . The control ends of the adjustment bolt 13 and the adjustment linkage assembly 14 are both arranged on the skirt 110 of the reflective plate 11 close to the first support plate 3 .

[0044] With the above structure, the skirt 110 provides an installation position for the control end of the adjusting bolt 13 and the adjusting linkage assembly 14, so that the reflector 11 can be detachably connected to the first support plate 3 through the adjusting bolt 13. In addition, the reflector 11 can be changed in position through the adjusting bolt 13 to achieve the function of radiating in different directions.

[0045] Furthermore, one end of the limiting plate 144 extends outward and passes through the skirt 110 close to the first support plate 3; an adjusting oblong hole 1442 is provided at the proximal end of the other end of the limiting plate 144, and the upper end of the connecting column 146 can be detachably assembled in the adjusting oblong hole 1442.

[0046] By adopting the above structure, the limit plate 144 can be slid to adjust the position of the connecting column 146 on the adjusting oblong hole 1442, so that the position of the limit sliding groove 1441 is changed, thereby adjusting the sliding range of the transmission sleeve 142, thereby adjusting the horizontal azimuth angle range according to actual conditions.

[0047] Optionally, the reflective plate 11 is provided with an avoidance oblong hole 111, the phase shifter 15 is arranged at the bottom of the reflective plate 11, the linkage rod 143 is slidably assembled at the bottom of the reflective plate 11, and a connecting block is provided at the bottom of the transmission sleeve 142, and the connecting block passes through the avoidance oblong hole 111 and is connected to one end of the linkage rod 143.

[0048] With the above structure, the linkage rod 143 and the phase shifter 15 are arranged at the bottom of the reflector 11 , which saves space on the upper surface of the reflector 11 and facilitates the arrangement of the antenna units in the antenna array unit 12 .

[0049] Preferably, it also includes a protective cover 5, which is arranged on the outer periphery of the two groups of antenna units 1, the first support plate 3 and the second support plate 4. The protective cover 5 has an adjustment opening 51 on the side close to the first support plate 3, and the protective cover 5 is detachably connected to a protective plate 52 at the opening of the adjustment opening 51.

[0050] The protective cover 5 plays the role of the two groups of antenna units 1, the supporting base plate 2, the first supporting plate 3 and the second supporting plate 4, preventing debris or small animals from entering the split antenna structure and causing structural damage.

[0051] When the vertical azimuth and horizontal azimuth of the installed antenna need to be adjusted, it is not necessary to open the protective cover 5 , but only to open the protective plate 52 , and the adjustment bolt 13 and the adjustment screw 141 can be operated through the adjustment opening 51 .

[0052] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementations of the present invention without creative work, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
