[0022] Reference Figure 1A horizontal small flat-panel indoor distributed antenna according to an embodiment of the present invention includes: an antenna cover 1, a dielectric substrate 2, a phase shifter 3, a phase modulation assembly 4, and radiating elements 5. The outer side of the antenna cover 1 is detachably mounted on the surface of a building, and the interior of the antenna cover 1 forms a reflective cavity 11 for mounting and accommodating the antenna. A portion of the surface of the dielectric substrate 2 is recessed to form a mounting notch 21, and a plurality of radiating elements 5 arranged in an array are fixedly mounted on one side of the dielectric substrate 2. (Refer to...) Figure 2 The fixed end of the phase shifter 3 is fixedly positioned above the mounting notch 21, and the movable end of the phase shifter 3 is rotatably connected to the adjustment assembly. The adjustment assembly includes: two stabilizing seats 41, a lead screw 42, a guide frame 43, an adjustment knob 44, and a transmission component 45. Each stabilizing seat 41 is arranged opposite to each other, and the outer side of each stabilizing seat 41 is fixed to one side of the edge of the dielectric substrate 2. Each stabilizing seat 41 has a bearing on its inner side. One end of the lead screw 42 is inserted into each stabilizing seat 41, and the other end of the lead screw 42 extends out of the reflection cavity 11 and is fixedly connected to the adjustment knob 44. The outer periphery of the lead screw 42 is rotatably connected to one end of the guide frame 43, and the other end of the guide frame 43 is fixedly connected to the outer side of the transmission component 45. The inner side of the transmission component 45 is movably connected to the movable end of the phase shifter 3, and the outer side of the transmission component 45 is fixedly connected to the guide frame 43. After rotating the adjustment knob 44, the lead screw 42 drives the phase shifter 3 to move, thereby completing the phase adjustment.

[0023] Refer to together Figure 2 and Figure 3 Specifically, the phase shifter 3 includes a phase disk 31, a swing arm 32, a side arm 33, and a guide plate 34. The phase disk 31 is generally plate-shaped, with one of its outer edges curved to form an arc structure. The phase disk 31 is detachably fixed above the mounting notch 21 by bolts or other connecting parts, and the centerline of the phase disk 31 is collinear with the centerline of the entire dielectric substrate 2. The swing arm 32 is located on the side of the phase disk 31 away from the radiation unit 5, and one end of the swing arm 32 is fixedly connected to one end of the side arm 33 via a pivot. The side arm 33 is located on the side of the phase disk 31 closer to the radiation unit 5, and the other end of the side arm 33 is fixedly connected to the other end of the swing arm 32 via the guide plate 34. The wide surface of the guide plate 34 is an arc surface that matches the arc side of the phase disk 31, and the narrow surfaces of the guide plate 34 protrude outwards to form pins 341. The surface of the swing arm 32 is provided with a guide hole 321, and the surface of the side arm 33 is provided with a first guide groove 331 extending along the surface of the side arm 33. One of the pins 341 passes through the guide hole 321, and the other pin 341 passes through the first guide groove 331 and the transmission member 45, thereby forming a rotatable movable part on the outer periphery of the phase disk 31.

[0024] Furthermore, the transmission component 45 is generally a triangular block shape, and a second guide groove 451 is provided on the inner side of the transmission component 45. The outer side of the transmission component 45 is fixedly connected to the guide frame 43, and a pin 341 passes through the second guide groove 451. When the lead screw 42 rotates, the guide frame 43 drives the transmission component 45 to move linearly. Under the combined action of the second guide groove 451 and the pin 341, the pin 341 moves relative to the lead screw 451, thereby driving the movable component composed of the swing arm 32 and the side arm 33 to move in a circular motion.

[0025] Further, the stabilizer includes a first part 431 and a second part 432. One end of the first part 431 is rotatably connected to the lead screw 42, and the other end of the first part 431 is continuously bent and fixedly connected to the second part 432. The second part 432 is disposed on the inner wall of the reflecting cavity 11, and the second part 432 is in the shape of a long strip plate, with the extension directions of the first part 431 and the second part 432 perpendicular to each other. The second part 432 and the lead screw 42 are located on opposite sides of the reflecting cavity 11 in the width direction, and are parallel to each other. The second part 432 is located on the side of the phase disk 31 near the arc-shaped region, and both the second part 432 and the lead screw 42 are located in the area where the mounting notch 21 on the surface of the dielectric substrate 2 is located.

One end of the second part 432 passes through the retaining sleeve 311 and is fixedly connected to the outside of the transmission member 45 to ensure that the force on the transmission member 45 remains stable during the movement of the second part 432.

[0027] Furthermore, to improve the phase modulation effect, in other embodiments, the entire horizontal small flat panel indoor antenna also includes a scale 6. One end of the scale 6 protrudes and extends outward to form a limiting part 61, and the other end of the scale 6 passes through the reflector cavity 11 and is fixedly connected to the measuring connector 7. To improve the stability of the scale 6, in another embodiment, the narrow surface at the high end of the first part 431 extends downward to form a positioning plate 433, and the surface of the baffle is provided with a first limiting groove 4331. One end of the scale 6 passes through the first limiting groove 4331 and is connected to the measuring connector 7 outside the antenna cover 1. The surface of the scale 6 is provided with corresponding scales, and the width of the limiting part 61 is greater than the width of the first limiting groove 4331.

[0028] Furthermore, to improve the stability of the scale 6, in another embodiment, a limiting seat 22 is also provided on the surface of the dielectric substrate 2. The limiting seat 22 has a second limiting groove opposite to the first limiting groove 4331. One end of the scale 6 passes through the first limiting groove 4331 and the second limiting groove in sequence, exits the reflective cavity 11, and is fixedly connected to the measuring connector 7.

Each base 12 is arranged opposite to each other, and each base 12 is symmetrically distributed about the center line of the phase disk 31. The adjustment frame 13 is generally arched, and its two sides are detachably connected to the bases 12 by bolts or other connecting parts. After the installation tilt angle and the overall orientation of the antenna are adjusted, the corresponding connecting parts are inserted.

[0031] In summary, this invention optimizes the internal structure of the antenna to form a compact whole, and achieves phase adjustment through the cooperation of the phase shifter and the direction adjustment component.
