The wideband multiport base station antenna radiation boundary has properties of simple structure and low cost, has obvious improvement effects on wave beam distortion caused by unit column signal coupling, can further realize horizontal plane wave beam convergence and improves gain so as to improve antenna radiation performance.
Description
Technical field
The present invention relates to moving communicating field, be specifically related to a kind of wideband multiport base station antenna radiation border.
Background technology
In cell mobile communication systems, antenna is the important component part of mobile communication system, and the performance of antenna directly affects the overall performance of mobile communication network.Multi-port antenna covers in sector in cellular mobile communication, and System Expansion and beam position regulate comparatively traditional antenna to have greater advantage.But consider antenna design method, placement 4 row radiating element will be concentrated in less width to form eight terminal port antennaes, while antenna volume that densely arranged radiating element is less greatly, bring the deterioration of aerial radiation index, adjacent nearer radiating element changes radiation characteristic as metal radiation border, also has larger coupling to disturb and take part in radiation, cause the distortion of antenna beam, beamwidth is discrete, and gain fluctuation is large, and index is difficult to control.
Along with the development of 4G communication, antenna introduces 2.6G frequency range, and the wavelength shorter relative to 2.6G frequency range, antenna array spacing is reduced into 75mm further, and between antenna unit array, influential effect strengthens further.
The implementation on tradition multi-port antenna radiation border is between cell columns and antenna-reflected plate both sides install vertical metal baffle additional, the height of suitable adjustment vertical baffle, certain regulating action can be had to beamwidth, the distortion of antenna beam, beamwidth is discrete, and gain fluctuation is the problem that smart antenna field is difficult to capture greatly always.
Summary of the invention
Too small in order to solve wideband multi-port antenna cell columns spacing, the distortion of the antenna beam that boundary effect and coupling effect cause, beamwidth is discrete, the problem that gain fluctuation is large, a kind of wideband multiport base station antenna radiation border structure disclosed by the invention is simple, with low cost, machining accuracy susceptibility is lower, has larger value to Antenna Design and production.
The present invention places four array antenna radiant bodies in reflective back plane main body, separate with row baffle plate between four row, side is positioned at reflective back plane main body both sides, row baffle plate is made up of angled two inclined-planes, side and the angled bending of reflecting plate subject plane, in four row radiating elements, each radiation border, row inner side becomes symmetrical, and above each several part forms the radiation border of an entirety as wideband multiport antenna for base station.
Concrete technical scheme is as follows:
A kind of wideband multiport base station antenna radiation border, comprises reflective back plane main body (3), side (1), row baffle plate (2), radiation element (4); Radiation element (4) is the radiating element of one ± 45 ° polarization, radiation element (4) is placed perpendicular to reflecting plate (3), multiple radiation element longitudinally array distribution, form 4 arrays respectively, and coordinate feeding network and radome, composition wideband multiport antenna for base station.
Described reflective back plane main body (3) is separated into 4 column spaces by row baffle plate (2) and side (1), and every column space is used for placing radiation element, radiation border longitudinally Central Symmetry.
Described row baffle plate (2) forms down " V " type by two inclined-planes, side (1) and the angled bending of reflective back plane main body (3) planar shaped, and in four row radiation elements, each radiation border, row inner side becomes symmetrical.
Described row baffle plate (2), side (1) can adjust according to different radiant bodies from reflective back plane main body (3) plane angulation respectively.
As preferably, the implementation on this radiation border can pass through section bar pultrusion one-shot forming.Also can panel beating be assembled by rivet or screw, specific implementation is determined according to cost and assembly technology.
As preferably, the antenna that described boundary condition is formed comprises the antenna forming different length different gains in this manner, also can increase phase shifter structure on said structure, composition electrical tilt antenna.
A kind of wideband multiport base station antenna radiation border disclosed in this invention, compared with prior art, the present invention passes through the antenna-reflected plate of special type, from the problem reducing the deterioration of antenna index largely.And implementation structure is simple, with low cost, to the design of smart antenna with produce and have larger value.
Have and comprise following advantage:
