|1. (WO2018218515) ANTENNA FEEDING STRUCTURE AND ANTENNA RADIATION SYSTEM|
|Applicants:||HUAWEI TECHNOLOGIES CO., LTD.
|Title:||ANTENNA FEEDING STRUCTURE AND ANTENNA RADIATION SYSTEM|
The embodiments of the present application relate to an antenna feeding structure and an antenna radiation system. The antenna feeding structure comprises a reflective plate, at least one low frequency radiation unit and at least one high frequency radiation unit, wherein the high frequency radiation unit and the low frequency radiation unit are both arranged on the reflective plate; the high frequency radiation unit comprises a layer-shaped grounding assembly, with the grounding assembly comprising a signal earth layer; at least one through hole is arranged on the reflective plate, and the position of the through hole corresponds to that of the high frequency radiation unit, and the grounding assembly in the high frequency radiation unit covers the corresponding through hole; and the area of an overlapping region between the signal earth layer and the reflective plate is less than a pre-set threshold value. The antenna feeding structure and the antenna radiation system provided in the embodiments of the present application make the antenna feeding structure simpler on the basis of reducing the interference between a high frequency radiation unit and a low frequency radiation unit, thereby reducing the manufacturing cost of the structure.
