As shown in fig. 1 to 3 and 5, in one embodiment, there is provided a feeding structure 10 including a first high-frequency radiation unit 100, a reflection plate 200, and a feeding network 300. The first high-frequency radiating unit 100 includes a first balun 110 and a first feeding component 120. The reflection plate 200 is provided with a first side surface 210 and a second side surface 220 which are oppositely arranged at intervals, and a first through hole 230 which penetrates through the first side surface 210 and the second side surface 220, and the diameter of the first through hole 230 is larger than the outer diameter of the first balun 110. The feeding network 300 includes a metal cavity 310 fixedly disposed on the second side surface 220, and a feeding network component 320 disposed in the metal cavity 310, and a second through hole 311 disposed on a sidewall of the metal cavity 310 and corresponding to the first through hole 230.

The first feeding component 120 may be provided in the form of a feeding plate, a through hole for the feeding plate to pass through may be formed in the first balun 110, one end of the feeding plate and the first radiator 130 may adopt a coupling feeding manner, and the other end of the feeding plate may adopt a welding manner to achieve an electrical connection with the feeding network component 320. The size of the first through hole 230 needs to be adapted to the outer contour of the first balun 110, so that the first balun 110 can smoothly pass through the first through hole 230 and the first balun 110 is not connected to the reflective plate 200. The feeding network component 320 may be provided as a circuit board provided with strip lines.

The distance between the first radiator 130 and the reflection plate 200 (indicated by L in fig. 1) is equal to or approximately equal to a quarter wavelength of the center frequency point corresponding to the operating frequency band of the first high-frequency radiation unit 100. In this way, the first high-frequency radiation unit 100 can be ensured to have good radiation performance. The distance between the first radiator 130 and the reflective plate 200 is the distance between the surface of the first radiator 130 and the first side surface 210. The approximate equivalence is considered to be equal within an allowable error range considering the influence of machining errors and installation errors.
As shown in fig. 6 and fig. 9, on the basis of any of the above embodiments, the metal cavity 310 is further provided with a welding hole 312 for welding the first feeding component 120 and the feeding network component 320.

Therefore, the internal structure of the antenna is compact, and the size of the antenna can be reduced.

In one embodiment, the distance between the low frequency radiator 410 and the reflection plate 200 is equal to or approximately equal to a quarter wavelength of a center frequency point corresponding to an operating frequency band of the low frequency radiation unit 400. Thus, the low-frequency radiation unit 400 can be ensured to have good radiation performance. The distance between the low frequency radiator 410 and the reflection plate 200 is the distance between the surface of the low frequency radiator 410 and the first side surface 210.

As such, one end of the second feeding component 510 may pass through the third through hole of the low frequency radiator 410; after the first coaxial cable 520 passes through the fourth through hole 240, the first coaxial cable 520 is used to realize the electrical connection between the second feeding component 510 and the feeding network component 320; the other end of the second feeding component 510 is connected to the second radiator 530 of the second high-frequency radiation unit 500 to feed the second radiator 530; thereby, energy can be smoothly transmitted to the second radiator 530, and the radiation performance of the second high-frequency radiation unit 500 is ensured. The second feeding member 510 may be provided in the form of a feeding sheet. Meanwhile, the length of the first coaxial cable 520 can be flexibly adjusted, so that network parameters can be flexibly adjusted, and the generalization and index optimization of product design can be realized.

Thus, the second high-frequency radiation unit 500 can be ensured to have good radiation performance. The distance between the second radiator 530 and the reflective plate 200 is a distance between the surface of the second radiator 530 and the first side surface 210. The approximate equivalence is considered to be equal within an allowable error range considering the influence of machining errors and installation errors.
