Abstract
The utility model provides a dual-polarized radiation unit, which comprises a baffle board, a feeder circuit board, a main radiation sheet and a coupled guide sheet. The two diagonals of the main radiation sheet are provided with four rectangular holes. The aluminum sheet at each hole site is downwardly bent to be positioned at a 90-degree angle with respect to the main radiation sheet. The upper end of the aluminum sheet is integrally machined with the main radiation sheet to be formed. The lower end of the aluminum sheet is subjected to the plating treatment to be fixedly welded with the feeder circuit board on the baffle board. According to the technical scheme of the utility model, the excitation of the dual-polarized radiation unit for a base station antenna is realized in a diagonal four-point feeding mode, so that the two polarization of the radiation unit are good in isolation. The radiation unit also has the advantages of simple structure, fewer components, easy machining, small size and the like.
Description
Technical field
The utility model relates to the antenna for base station technical field, relates in particular to a kind of used in base station antenna dual-polarization radiating unit.
Background technology
In recent years, the 3G technology development, 3G subscription quantity also presents a rapidly rising trend, and this just in the urgent need to increasing the quantity of cellular cell, also needs to improve simultaneously the residential quarter covering quality.Face a lot of difficulties but implement:
One, existing base station number is a lot, and site resource is very in short supply, and NodeB is often selected to stand altogether with the 2G base station, and the space of setting up of antenna will be more and more less.
Two, the quantity of base station constantly increases, and means the more antenna of needs, and the cost of operator is also just higher.
Present smart antenna is only supported one-segment mostly, and that multifrequency antenna faces volume is large, and weight is large, baroque problem.Therefore accomplish small size, easily processing, assemble, seem more and more important.
The utility model content
The purpose of this utility model is to provide a kind of small size, the dual-polarization radiating unit of low-cost, easy processing, high-isolation.
The purpose of this utility model is achieved through the following technical solutions.
A kind of dual-polarization radiating unit, comprise: sheet is guided in reflecting plate, feeder board, primary radiation sheet, coupling into, four rectangular openings of structure on described primary radiation sheet two diagonal, the aluminium flake downward bending of each rectangular opening position becomes 90 degree angles with the primary radiation sheet, the upper end of described aluminium flake and the machine-shaping of primary radiation sheet one, the lower end of aluminium flake are carried out electroplating processes and are welded and fixed with feeder board on the reflecting plate.
Preferably, described primary radiation sheet and coupling are guided between the sheet and are fixed with plastic supporting pieces.
Preferably, to guide sheet into be square aluminum sheet structure for described primary radiation sheet and coupling.
Preferably, described four rectangular opening sizes are equal, and apart from primary radiation sheet Central Symmetry.
Preferably, described feeder board is 1 minute 2 the power splitter that amplitude distribution equates, 180 ° of the phase differences of two delivery outlets of power splitter.
The utility model compared with prior art, beneficial effect is: the used in base station antenna dual-polarization radiating unit that the utility model provides, owing to adopting diagonal angle four-point feed mode to encourage, therefore two polarization of radiating element have good isolation, and have the advantages such as simple in structure, that building block is few, easy processing, size are little.
Description of drawings

Fig. 2 is the utility model dual-polarization radiating unit end view.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also shown in Fig. 1,2, the utility model dual-polarization radiating unit comprises: sheet 4 is guided in reflecting plate 1, feeder board 2, primary radiation sheet 3, coupling into, and primary radiation sheet 3 and coupling are guided between the sheet 4 and be fixed with plastic supporting pieces 6.
Above-mentioned four rectangular opening sizes are equal, and apart from primary radiation sheet 3 Central Symmetries.
The approximately wide 4mm of the width of the Width aluminium flake 5 of the rectangular opening on the above-mentioned primary radiation sheet, about keep somewhere the 2mm gap, the phase phasic difference is 180 ° between two distributing points of same polarization.
Above-mentioned feeder board is 1 minute 2 the power splitter that amplitude distribution equates, 180 ° of the phase differences of two delivery outlets of power splitter.
Two distributing points of each polarization of radiating element are that the power splitter by 1 minute 2 links up, two aluminium flakes welding feeds that two ports of 1 minute 2 power splitter and same polarization bending are got off, 180 ° of two distributing point phases phasic differences of same polarization.
The used in base station antenna dual-polarization radiating unit that the utility model provides, the operating frequency of its antenna oscillator is: 1710MHz ~ 2170MHz, under the prerequisite that satisfies the oscillator performance, the height of oscillator is not higher than 25mm.
The used in base station antenna dual-polarization radiating unit that the utility model provides, owing to adopting diagonal angle four-point feed mode to encourage, therefore two polarization of radiating element have good isolation, and have the advantages such as simple in structure, that building block is few, easy processing, size are little.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
