Embodiment
Below, with reference to accompanying drawing, structure of the present utility model and operation principle etc. are further described.
As shown in Figure 1 and shown in Fig. 2, Fig. 1 shows for the structure of the antenna for base station described in the utility model for high frequency decoupling
It is intended to, Fig. 2 is the structural representation of oscillator radiating surface 1 described in the utility model.The antenna for base station for high frequency decoupling
Structure includes oscillator radiating surface 1 and supporting surface 2, and the oscillator radiating surface 1 is formed by connecting by two layers of copper face square crossing up and down,
In the utility model preferred embodiment, two layers of copper face up and down is connected by the way of coupling or via, so as to improve
Own bandwidth；
Radiation blade 3 is provided with the copper face, in the utility model preferred embodiment, on the copper face respectively
Left and right two panels radiation blade 3 is provided with, the shape of the left and right two panels radiation blade 3 is identical and using the center line of the copper face as axle
Left and right is symmetrical, and one end of the radiation blade 3 is arranged on the center of the copper face, and the other end extends to the end of the copper face
Portion；Meanwhile, the radiation blade 3 uses gradual design, i.e.,：The width of the radiation blade 3 is from the center of the copper face to institute
The end for stating copper face gradually broadens；
A section or more piece filter network 4 are provided with the radiation blade 3, the joint number of the filter network 4 and position take
The CURRENT DISTRIBUTION of low frequency blade certainly when high frequency pumping, in the utility model preferred embodiment, the filter network 4 is one
Section, and the filter network 4 uses symmetrical H types structure, the filter network 4 of the symmetrical H types structure can be in multiband
In antenna for base station environment, good decoupling performance is realized.
As shown in figure 3, Fig. 3 is the structural representation of the supporting surface 2.The supporting surface 2 is the balun of chi structure, institute
The one end for stating supporting surface 2 is fixed on the fixing point 5 of the oscillator radiating surface 1, and the fixing point 5 is two layers of copper face up and down
The crosspoint of square crossing combination, the top half of the balun offers one or more elongated slots, preferred in the utility model
Embodiment in, the supporting surface 2 is the balun of the chi structure based on PCB design, the first half of the balun of the supporting surface 2
Separately provided with an elongated slot 6, the elongated slot 6 is used to improve the cross polarization index of low side.One end of the supporting surface 2 is fixed on
On the fixing point 5 of the oscillator radiating surface 1, the fixing point 5 is the crosspoint that two layers of copper face square crossing is combined up and down.
As illustrated, in the utility model preferred embodiment, the choosing of the filter network 4 of the symmetrical H types structure
The position that takes is by optimization, from the point of view of the simulation result of CURRENT DISTRIBUTION, when the high frequency unit of excitation low frequency cell annex respectively+
