Embodiment Construction

[0016] Below, the structure and working principle of the present invention will be further described in conjunction with the accompanying drawings.

[0017] like figure 1 shown and figure 2 as shown, figure 1 It is a schematic structural diagram of a base station antenna for high-frequency decoupling according to the present invention, figure 2 It is a structural schematic diagram of the radiating surface 1 of the vibrator in the present invention. The structure of the base station antenna for high-frequency decoupling includes a dipole radiation surface 1 and a support surface 2. The dipole radiation surface 1 is formed by vertically cross-connecting two upper and lower layers of copper surfaces. In a preferred embodiment of the present invention, The upper and lower layers of copper surfaces are connected by means of coupling or vias, thereby improving their own bandwidth;

[0018] Radiating blades 3 are arranged on the copper surface. In a preferred embodiment of the ...

Abstract

The invention discloses a base station antenna used for high-frequency decoupling. The base station antenna comprises a vibrator radiation surface and a supporting surface; the vibrator radiation surface is formed by upper and lower layers of copper surfaces in a perpendicularly crossed and connected manner; the copper surfaces are provided with radiation blades; the radiation blades are providedwith filtering networks; one end of the supporting surface is fixed on a fixed point of the vibrator radiation surface; and the fixed point is a perpendicularly crossed and combined crossed point of the upper and lower layers of copper surfaces, so that the low-frequency broadband frequency is realized while influence on high frequency from low frequency is reduced; and meanwhile, by virtue of a slotting mode in the upper half section of a supporting surface balun, crossed polarization of a low-frequency low end is improved, and the radiation efficiency is not influenced.

Description
