Description
[technical field]
The utility model relates to the mobile communication antenna technical field, is specifically related to a kind of base station with dual polarization shot-light antenna.
[background technology]
Antenna is one of critical component in the wireless communication system, and its pattern shapes and index and method for using will directly have influence on the coverage effect of signal of communication.
Antenna for base station is a kind of device that is used to transmit and receive mobile communication signal, is used to receive and launch the movable signal in certain sub-district.Existing antenna for base station can't adapt to the design feature of modern city high constructure fully.Particularly, city high rise building has high and narrow characteristics, covers if use existing antenna to carry out signal, then needs the antenna lower decline angle can not be too big, and signal could effectively cover the high-rise regional of high building like this.Yet, because city high rise building width relative narrower, and the covering of existing city uses the horizontal beam width of antenna for base station to be mostly 65 °; If antenna tilt is too little; Then be easy to make signal to leak from the high building side, cover other neighbor cells, the district disturbs thereby cause more easily.
If above-mentioned coverage mode is all adopted in especially a plurality of base stations, do not disturb even do not produce the adjacent area, the signal of communication that same high building is received the different districts antenna for base station emission that several signal strength signal intensities are suitable also appears easily, caused the covering phenomenon.This mistake covers phenomenon and tends to cause mobile subscriber at this place in communication process; Along with the user position is different, the signal strength signal intensity that receives can change, and possibly cause frequent switching signal between several neighbor cells; Make the computational burden of main equipment strengthen, cause the wasting of resources.
Another kind of effective coverage mode to high building is to adopt indoor signal to cover, and the mode that just adopts the repeater to add the chamber divided antenna covers signal each premises of high-rise resident family.But for residential quarters, the covering difficulty of registering one's residence is very big, and the owner is often perhaps destroyed reasons such as finishing by radiation owing to worry, can actively not cooperate, and this can increase the coordination difficulty undoubtedly.In addition, concerning operator, covering cost also can increase a lot, drops into higher, economical inadequately.
Simultaneously; Along with the gradually understanding of user to radiated electromagnetic wave, covering generally has a kind of feared state of mind to electromagnetism, worries the health of radiation effect to oneself; Generally do not hope to see near the own home that antenna is arranged, so the place of selecting to build a station also becomes a problem that lets operator's headache.The user hopes that on the one hand signal is good; Do not hope again on the other hand antenna installation near oneself, so even the place of building a station coordinate successfully, if use existing antenna for base station; Also easily because the opposition of resident family is and stranded on every side, this has increased the covering difficulty of operator virtually.
[utility model content]
The purpose of the utility model be to provide a kind of simple in structure, build is small and exquisite and can let signal of communication effectively cover city high rise building and be difficult for causing base station that the adjacent area disturbs with dual polarization shot-light antenna.
For realizing this purpose, the utility model adopts following technical scheme:
A kind of base station comprises with dual polarization shot-light antenna: reflecting plate, with the matrix-style setting and be installed in a plurality of aerial radiation oscillators on the said reflecting plate, be arranged on the power division network at said reflecting plate back and with the fixing shot-light shell on it of said reflecting plate.Be covered with on the said shot-light shell in order to protect the emulation shot-light panel of said aerial radiation oscillator.Said a plurality of aerial radiation oscillator is realized electrical connection each other through said power division network.Said power division network links to each other with the rf feed joint through coaxial cable again.
Preferably, said power division network is one minute four power splitter, and the quantity of said aerial radiation oscillator is four, and said four aerial radiation oscillators electrically connect through said one minute four power splitter each other.In said lateral isolation plate and the vertical division board at least one be provided with in order to the insulating trip of reflecting plate mutual insulating.The horizontal beam width of said shot-light antenna is 30 °; The vertical beam width of said shot-light antenna is 32 °.
Compare with antenna for base station with existing city, the utlity model has following advantage: the horizontal beam width relative narrower, the relative broad of vertical beam width especially is fit to high and narrow high building signal and covers.
The horizontal beam width of relative narrower and the relative vertical beam width of broad are that the group battle array mode through a plurality of radiating elements on the reflecting plate realizes; And the critical component of realizing this group battle array mode is the power splitter of certain type; (be preferably one and advance four power splitters that go out such as one advancing to have more; Be also referred to as one minute four power splitter) power splitter; This power splitter is that all radiating elements on the reflecting plate provide a certain proportion of power division and certain phase place, thereby realizes the directional diagram index of this utility model.
In addition; The utility model profile and general lighting shot-light fairly similar, and cabling mode is also the same with the general lighting shot-light, and general layman can't penetrate; Therefore; Owner's ditch only need and be installed be had friendly relations, just worry basically that other owners complain, and have reduced the difficulty of building a station of operator to greatest extent.
