[0002] In the electrically adjustable base station antenna, the phase shifter is an important core component that affects the antenna performance. Whether the phase shifter is firmly installed and stably operates has a direct impact on the performance of the entire antenna. Existing cavity-type phase shifters are mostly installed in a flat-laying manner, and are assembled and fixed on the reflector with different plastic support parts. Cavity-type phase shifters are generally set in the middle of the dipole array to achieve the design requirements of the shortest branch feeder line. However, due to the large size of the cavity phase shifter, the flat-laying setting will block the dipole solder joints on the back, affecting the routing of the back branch feeder line.

[0008] Furthermore, the second part includes: a baffle and a rotating shaft; the two opposite narrow surfaces of the baffle extend in opposite vertical directions to form a first block-shaped protrusion and a second block-shaped protrusion respectively; wherein the first block-shaped protrusion is vertically connected to the first part, and the rotating shaft is respectively penetrated on the opposite surfaces of the second block-shaped protrusion.

[0009] Furthermore, the first part and the second part are vertically connected, and a reinforcing rib is provided at the connection between the first part and the second part.

[0010] Further, when the phase shifter is in the limiting groove, the cover plate is rotated so that the shaft card is embedded in the second notch or the fourth notch, the first block-shaped protrusion is embedded in the first notch or the third notch, and the second block-shaped protrusion is embedded in the first notch or the third notch.

[0016] In order to make the purpose, technical solution and advantages of the present application clearer, the present invention will be described in further detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] It should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this patent.

[0018] Figure 1 The figure is a schematic diagram of an installation structure of a support structure for a phase shifter according to an embodiment of the utility model.

[0019] Reference Figure 1 According to an embodiment of the utility model, a support structure for a phase shifter includes: a base 3, a first side arm 4, a second side arm 5 and a cover plate 6. One side of the base 3 is snap-connected with the reflector 1. Both sides of the base 3 are fixedly connected with the first side arm 4 and the second side arm 5, respectively, so that a limiting groove for accommodating the phase shifter 2 is formed on one side of the base 3. The surface of the first side arm 4 is spaced apart with protrusions, so as to form a first clamping groove 41 for limiting the branch feeder line 7. The surface of the second side arm 5 is spaced apart with protrusions, so as to form a second clamping groove 51 for limiting the branch feeder line 7. The cover plate 6 includes a first part 61 and a second part 62 connected vertically. When the phase shifter 2 enters the limiting groove, the first part 61 is fixedly connected to the surface of the first side arm 4, and the wide surface of the second part 62 abuts against the phase shifter 2, so that the phase shifter 2 is limited in the limiting groove.

[0020] Specifically, the first side arm 4 and the second side arm 5 are symmetrical about the midline of the base 3. The surface of the first side arm 4 and the surface of the second side arm 5 are both provided with through holes for fixing the cover plate 6. When the phase shifter 2 enters the limiting groove, the cover plate 6 closes the upper part of the limiting groove, the base 3 is snap-connected with the reflector 1, and the limiting groove in the base 3 surrounds the outer periphery of the phase shifter 2, thereby ensuring that the entire antenna does not shake during operation. The guiding effect of the first clamping groove 41 and the second clamping groove 51 on the branch feeder line 7 makes the length of the branch feeder line 7 after installation shorter than that of the existing design. On the one hand, this reduces the transmission loss of the signal in the feeder line, and on the other hand, the setting of the support structure greatly reduces the shielding area of ​​the back of the antenna by the phase shifter 2 after the phase shifter 2 is fixed.

[0021] Figure 2 The figure is a schematic diagram of an exploded structure of a support structure for a phase shifter according to an embodiment of the utility model.

[0022] Reference Figure 2, further, the free end of the first side arm 4 (the end away from the base 3) is recessed to form a first notch 42, and the extension direction of the first notch 42 is the same as the extension direction of the first portion 61. The side of the first notch 42 away from the second side arm 5 is recessed to form a second notch 43. The free end of the second side arm 5 (the end away from the base 3) is recessed to form a third notch 52, and the extension direction of the third notch 52 is the same as the extension direction of the first end. The side of the third notch 52 away from the first side arm 4 is recessed to form a fourth notch 53. After the phase shifter 2 is placed in the limiting groove, the cover plate 6 is fixed to the first side arm 4 or the second side arm 5 through the connecting member 9.

[0023] Figure 3 It is a schematic diagram of the three-dimensional structure of the cover plate 6 according to an embodiment of the utility model.

[0024] Reference Figure 3 , further, the second part 62 includes a baffle 621 and a rotating shaft 622. The baffle 621 extends in opposite vertical directions relative to the two narrow faces, respectively, thereby forming a first block-shaped protrusion 6211 and a second block-shaped protrusion 6212, respectively. The first block-shaped protrusion 6211 is fixedly connected to the first part 61, and a reinforcing rib 8 is provided at the connection between the first block-shaped protrusion 6211 and the first part 61. The two opposite narrow faces of the second block-shaped protrusion 6212 are respectively penetrated by rotating shafts 622, and each rotating shaft 622 is parallel to the narrow face of the baffle 621. When the cover plate 6 is installed, the rotating shaft 622 is inserted into the second notch 43 or the fourth notch 53, and then the first part 61 is rotated to a position matching the through hole on the surface of the first side arm 4 or the second side arm 5 with the rotating shaft 622 as the axis. After the connector 9 is inserted, the cover plate 6 is fixed on the first side arm 4 or the second side arm 5, and the first block protrusion 6211 and the second block protrusion 6212 of the baffle 621 are respectively embedded in the first notch 42 and the third notch 52. At this time, the cover plate 6, the first side arm 4, the second side arm 5 and the base 3 together form a ferrule surrounding the outer peripheral surface of the phase shifter 2, thereby fixing one end of the phase shifter 2 to reduce the interference of the external environment on the operation of the base station antenna.

[0025] Furthermore, a protrusion on one side of the base 3 away from the first side arm 4 (or the second side arm 5) forms a fixing buckle that matches the surface of the reflector 1. The surface of the reflector 1 is provided with a buckle hole and positioning holes distributed around the buckle hole. In order to further strengthen the connection between the base 3 and the reflector 1, a lock hole is further provided on one side of the base 3 close to the reflector 1. When the fixing buckle on the base 3 is pressed and embedded in the buckle hole, a connector 9 is inserted after the lock hole is aligned with the positioning hole to further strengthen the connection between the reflector 1 and the base 3. In this embodiment, the connector 9 includes but is not limited to fasteners with threads such as rivets and screws.

[0026] In summary, the utility model provides a new type of supporting structure so that during the installation process, the phase shifter can be installed under the condition of a narrow vertical reflector through the first wire clamping groove and the second wire clamping groove on the side. This not only shortens the length of the feeder line after installation, but also reduces the shielding area of ​​the phase shifter on the back of the antenna.
