Antenna for base station is operated under the complicated mobile communication environments, and mobile channel is subjected to Effect of Environmental such as landform, temperature, humidity usually, will be subjected to many-sided decline aloft when mobile electric wave is propagated, and these all can produce adverse influence to communication quality.And one of target of communication system optimization is exactly for people provide the acceptable communication quality, therefore must take necessary technology means and method to improve communication quality.The design of antenna for base station can not only be confined to the design of antenna electricity itself, but will be from the angle of system design, take all factors into consideration factors such as propagation, system and environmental condition, fully excavate whole potentiality of antenna hardware, form the Multi-Function Antenna system that satisfies system requirements.
But the base stations in mobile communication system antenna of prior art is difficult to reach the requirement of this broadband, dual polarization, high-isolation and high cross polarization resolution, as in please number be 99806235, the applying date is that June 16, denomination of invention in 1999 are the patent application that is used for the antenna of mobile communication, this is used for the antenna of mobile communication, comprise: first and second housings of conductor, each housing all has annular element, and the length of this annular element and diameter design when the frequency of considering antenna and gain characteristic; A separator, it is that a kind of non-conductor is made, and is arranged between first and second housings, so that keep the spacing of a regulation between the respective annular part of first and second housings according to frequency and gain characteristic; An inner core, it interfixes two housings with the threaded portion that inserts in the screw channel respectively, and each threaded portion all passes the bottom of annular element, and the first housing conduction formula is connected on second housing; With a coupling unit, the feeder line that is used for mobile communication terminal receipts/Power Generation Road connects.Antenna of the present invention is installed in the box of cellular telephone and does not reach the outside of this box.In addition, can this antenna be installed on the motor vehicle with an antenna base.Above-mentioned antenna is difficult to reach this demand equally.
Summary of the invention
The purpose of this utility model provides a kind of high performance template antenna for base station, adopt novel radiating element and feeding network, make the utility model not only satisfy the needs of 3G (Third Generation) Moblie, can also cover digital communication system (DCS) and PCS Personal Communications System (PCS) simultaneously, can also be applied in the emerging communication system such as Wimax.
In order to achieve the above object, antenna of the present utility model is made up of reflecting plate and the radiating element oscillator that is distributed on the reflecting plate, the radiating element oscillator is a umbrella shape, each oscillator is connected by feeding network, this umbrella shape oscillator adopts the coaxial feed mode to be made up of copper pipe and feeder line, copper pipe and feeder line all adopt hierarchic structure, cross-lapping feeder line between the top of the copper pipe that promptly is oppositely arranged, and the upper outside of copper pipe is connected with extension bar and constitutes umbrella shape; Described reflecting plate is the metallic reflection plate that has frame, and its cross section is a bathtub construction.
Described copper pipe all is fixed on the base, and its bottom is provided with two connectivity ports; Two connectivity ports connect and compose the parallelly feeding network; Also be stamped radome on the flute profile reflecting plate.
Also be provided with the bonding jumper of the intersection that is crisscross arranged up and down between adjacent umbrella shape radiating element oscillator, bonding jumper is fixed on the reflecting plate by the medium post.
Adopt the antenna advantage of the present utility model of said structure to be:
The utility model is to set about from the technology such as figuration of novel radiating element design, reflecting plate design, antenna pattern, develops the board type antenna of broadband, dual polarization, high-isolation and high cross polarization resolution.
In order to make antenna can satisfy the horizontal radiation lobe width and to have bigger front and back specific characteristic, need the shape of reflecting plate be designed, reflection board structure of the present utility model can satisfy above-mentioned requirements.
In order to improve the isolation of antenna, strengthen the spacing between the oscillator, just can reduce mutual coupling easily, thereby improve the isolation of antenna, but can cause the length of antenna array to increase, and array pitch is too big, the directional diagram secondary lobe of antenna increases.The utility model has adopted the method that adds intersection cross bonding jumper in the middle of a plurality of oscillators, has improved the isolation of antenna greatly.
In cell mobile communication systems, require antenna for base station to using the alap level of another antenna irradiation of same frequency, and in service area the high as far as possible level of radiation.Because people always wish that the mobile subscriber has equal received signal level to improve near-far interference in this zone, this just requires antenna to have irradiation evenly in this service area, promptly requires the vertical plane lower half-space to have cosecant square figuration power radiation pattern; Also require the radiation level of antenna vertical plane upper half-space low as much as possible in addition, therefore must carry out the wave beam forming design to the directional diagram of base station array antenna, this is the key factor of high-performance antenna for base station design.The utility model adopts constant amplitude not wait the parallelly feeding network of phase, and the last secondary lobe of antenna is forced down, and the following lobe first zero obtains filling.
