[0028] Specifically, the Z-shaped induction sheet 2 is used as a 380-520MHz induction sheet, and the vibrator mounting plates 3 include two. The two vibrator mounting plates 3 have the same structure. Each vibrator mounting plate 3 is correspondingly provided with a group of nylon columns 4, the first to fifth vibrator radiators 51-55, 4G wall-mounted electroplated induction sheets 6, 6G circuit boards 7, 4G circuit boards 8, cables 9, nylon studs 10, large-hole terminal blocks 11, and grounding wires 12.

[0030] In an embodiment of the present invention, the Z-shaped induction plate 2 serves as a 698-2700MHz oscillator induction plate, and the first to fifth oscillator radiators 51-55 include three 698-960MHz radiating oscillators and two 1425-2700MHz radiating oscillators. In the present invention, the oscillator radiators 51, 52, and 53 are 698-960MHz radiating oscillators, and the radiators 54 and 55 are 1425-2700MHz radiating oscillators.

[0031] Three 698-960MHz radiating elements (i.e. 51, 52, and 53) among the first to fifth radiator radiators constitute the 698-960MHz frequency band radiator of the wall-mounted antenna, and two 1425-2700MHz radiating elements (i.e. 54 and 55) among the first to fifth radiator radiators constitute the 1425-2700MHz frequency band radiator of the wall-mounted antenna.

[0032] In the present utility model, if Figure 3As shown, the first to fifth dipole radiators 51-55 are integrated and installed on the dipole mounting plate 3 according to a specific position relationship, and then suspended (for example, the bottom surface of the dipole mounting plate is 39mm away from the bottom plate) and fixed on the bottom plate 1. This structure makes the 698-2700MHz dipole not only meet the antenna radiation pattern and gain requirements, but also makes its impedance in the 698-2700MHz frequency band in a better matching state. At the same time, the Z-shaped induction plate 2 with a frequency band width of 698-2700MHz (located between the right side of the dipole radiator and the bottom plate 1) further optimizes its impedance matching, so that the antenna 698-960MHz standing wave is ≤2.0, and the 1425-2700MHz standing wave is ≤1.8.

[0033] In the embodiments of the present invention, Figure 5 As shown, the 6G circuit board 7 constitutes the 4900-6000MHz frequency band oscillator of the wall-mounted antenna, and the 6G circuit board 7 is placed 20mm below the oscillator mounting plate 3 and 19mm above the bottom plate.

[0034] Furthermore, if Figure 7 As shown, the 6G circuit board 7 has two first rectangular radiating elements 71. The size of the first rectangular radiating element 71 may be 20*9.5 mm, and the distance between the two first rectangular radiating elements is 16 mm.

[0035] Specifically, the 4900-6000MHz frequency band oscillator 6 is an inductive radiator with a specific "=" shaped structure printed on the 6G circuit board 7, which is placed 20mm below the 698-2700MHz frequency band oscillator and 19mm from the bottom plate. This position puts the 4900-6000MHz frequency band oscillator in a relatively ideal impedance matching state, with a standing wave ≤2.0.

[0036] According to one embodiment of the utility model, Figure 8 As shown, the 4G circuit board 8 has two second rectangular radiating oscillators 81, which constitute the 3300-4200MHz frequency band oscillators of the wall-mounted antenna. The distance between the 4G circuit board 8 and the oscillator mounting plate 3 can be 15mm.

[0037] Furthermore, the size of the second rectangular radiating element 81 may be 30*9.5 mm, and the distance between the two rectangular radiating elements 81 is 16 mm.

[0038] According to one embodiment of the utility model, Figure 3 As shown, the 4G wall-mounted electroplated induction sheet 6 constitutes a 3300-4200MHz oscillator induction sheet. The 4G wall-mounted electroplated induction sheet 6 is welded at the bend of the welding foot of one of the first to fifth oscillator radiators 51-55. In the utility model, the 4G wall-mounted electroplated induction sheet 6 is welded at the bend of the welding foot of the second oscillator radiator 52.

[0039] Specifically, the 3300-4200MHz frequency band vibrator is an inductive radiator with an "=" shape structure printed on the 4G circuit board 8, which is placed above the 698-2700MHz frequency band vibrator and 15mm away from the 698-2700MHz vibrator. A 3300-4200MHz 4G wall-mounted electroplated inductive sheet 6 is added between the two vibrators (welded at the bend of the welding foot 52 of the 698-2700MHz second vibrator radiator). The 3300-4200MHz frequency band vibrator (4G circuit board 8) utilizes a specific "=" shape structure and a specific positional relationship with the 698-2700MHz frequency band vibrator, which not only meets the antenna radiation pattern and gain requirements, but also puts the impedance in a relatively ideal matching state. In addition, the adjustment of the 4G wall-mounted electroplated inductive sheet 6 further optimizes its impedance matching, so that the antenna 3300-4200MHz standing wave is ≤1.8.

[0040] In the embodiments of the present invention, Figure 6 As shown, each vibrator mounting plate 3 is correspondingly installed with two grounding wires 12, the length of one grounding wire 12 is 180 mm, and the length of one grounding wire 12 is 160 mm. One end of the 180 mm grounding wire is welded to one of the 698-960 MHz radiating vibrators among the first to fifth vibrator radiators 51-55, and the other end of the 180 mm grounding wire is welded to a large hole terminal 11; one end of the 160 mm grounding wire is welded to another 698-960 MHz radiating vibrator among the first to fifth vibrator radiators 51-55, and the other end of the 160 mm grounding wire is welded to another large hole terminal 11.

[0041] Specifically, Figure 6 As shown, one end of a 180 mm long ground wire 12 is welded to the first radiator 51. Figure 6 The other end is welded to the large hole terminal 11 of the bottom plate 1; another 160mm ground wire is welded to the second oscillator radiator 52 as shown in FIG. Figure 6 The other end is welded to the large hole terminal 11 of the base plate 1.

[0042] It should be noted that the length of the grounding wire 12, the welding position of the grounding wire 12 and the radiator, and the position of the large-hole terminal 11 on the base plate 1 are obtained through repeated calculations and tests. Their function is to make the impedance of the 380-520MHz oscillator in a relatively ideal matching state while meeting the requirements of the antenna radiation pattern. In addition, the 380-520MHz induction plate (Z-type induction plate 2) further optimizes its impedance matching, so that the 380-520MHz standing wave is controlled at ≤2.5.

[0043] To sum up, according to the wall-mounted antenna of the utility model, through the 698-2700MHz frequency band vibrator, the 4900-6000MHz6G circuit board, the 3300-4200MHz 4G circuit board, the 698-2700MHz frequency band vibrator and the bottom plate connected by the ground wire to form a 380-520MHz frequency band vibrator, an antenna radiator with different frequency bandwidths is formed, so that communication with a frequency bandwidth of 380-6000MHz can be achieved on the same antenna, with low cost and small space occupation.
