The base station broadband radiating unit has the advantages that: the radiating unit is arranged along the extending direction of the reflecting bottom plate, and the vibrator and the vibrator base of the radiating unit are integrally molded by die-casting at one time, so that the base station broadband radiating unit is high in consistency, short in processing time, low in cost, high in accuracy, and high in electrical performance such as gain and standing wave; a tin-coating layer or a silver-coating layer is arranged on the surface of the vibrator, so that the surface finishment and weldability of the vibrator are guaranteed; and two sides of the reflecting bottom plate are bent upwards, so that the electrical performance of the radiating unit is guaranteed, and mechanical strength is improved.
Description
Technical field
The utility model relates to a kind of antenna element, particularly a kind of base station wideband radiating element.
Background technology
As electromagnetic R-T unit, the transmission of signal covers and be unable to do without antenna for base station in the mobile communication technology, and the dual polarization mobile base station antenna is the indispensable part in each base station, and its performance directly influences the quality of communication; And radiating element is the key component that influences dual polarization mobile base station antenna performance as the element of dual polarization mobile base station antenna.There is following problem in the radiating element that generally adopts now: gain on the low side, bandwidth is narrow partially, section is higher, the third order intermodulation index is undesirable, these problems cause the communication quality in the service area to can not get guarantee.
Summary of the invention
The technical problem that the utility model will solve provides a kind of gain high and base station wideband radiating element easy to process.
For solving the problems of the technologies described above, the technical scheme of the utility model is: a kind of base station wideband radiating element comprises reflected bottom plate and is installed in the radiating element on the reflected bottom plate that its innovative point is: said radiating element is provided with along the reflected bottom plate bearing of trend; Said radiating element comprises oscillator, oscillator chassis, insulation support and feed tab, said oscillator, oscillator chassis whole die cast, and the feed tab lower end is supported and fixed on the oscillator chassis through insulation, and the feed tab upper end is connected with oscillator.
Further, said oscillator is parallel with the reflected bottom plate surface.
Further, said oscillator surface is provided with tin coating or silver coating.
Further, the both sides of the said reflected bottom plate bending that makes progress.
The advantage of the utility model is: radiating element is provided with along the base plate bearing of trend, and the oscillator of radiating element, oscillator chassis be by casting forming of mold integral, and consistency is good; Process time is short; Cost is low, and precision is high, and electric properties such as gain, standing wave are outstanding.
The oscillator surface is provided with tin coating or silver coating, to guarantee surface smoothness and weldability.The bending that makes progress of the both sides of reflected bottom plate has improved mechanical strength when having guaranteed the electric property of radiating element.
