Description
Technical field
The present invention relates to the communication base station antenna, is a kind of antenna for base station figuration system and shaping method specifically.
Background technology
The mobile communication early stage of development, loss was low, the mechanical antenna of simplicity of design because the website surrounding enviroment are simple relatively, and web construction generally adopts cost low.In that telephone traffic was few at that time, surrounding enviroment can satisfy actual utilization under the situation preferably.But along with rapid development of mobile communication system, especially the development of the universal fast and 4G system of 3G system, base station distribution is more and more intensive in the city, and communications band is more and more, has directly brought between site resource anxiety, the base station and the signal covering problem such as has disturbed, disturb between the antenna.For this reason, mobile operator begins to adopt pattern characteristics better, and the electrical tilt antenna of more convenient adjusting angle of declination solves the problems referred to above.Simultaneously the optimization work that covers at the antenna for base station signal of specialty is also along with expansion, the network optimization troop of specialty also developed growth in these several years rapidly, solved the signal covering problem of a lot of real site, but had greatly the website problem still fail to solve, reason have following some.
1, the network planning at networking initial stage, can not adapt to the variation of present wireless environment, newly-increased high floor building causes division to signal, tears open and penetrates, reflection causes interference problem, plans originally that employed antenna model no longer mated with respect to present use scene.
2, in the implementation process of network optimization scheme, the antenna adjustment is necessary means, produce directly adjust effect in also can near the sub-district exert an influence.Whether the antenna adjustment has accurately directly determined the optimization effect, controls bad meeting and runs counter to desire.Therefore, the prioritization scheme of taking adjustment separately to have antenna now has been difficult to satisfy the network optimization requirement under the complex environment.
3, network optimization personnel to lack the guidance of necessary antenna knowledge and antenna figuration principle be to cause antenna to adjust repeatedly and fail to solve the major reason of website signal covering problem.The working centre of radio network optimization is the accurate control of wireless signal, in present radio network optimization work, has adopted these two major technology means of wireless parameter adjustment and antenna works parameter adjustment usually.Though see some problems that can solve network level from the work effect of reality, but owing to deficiency for antenna understanding itself, cause and emphasize simply to promote network quality or merely the network quality problem is laid the blame on to be the antenna performance deficiency by the antenna performance index, it is undesirable to cause optimizing effect at local sites, and quality of wireless network is difficult to improve.
4, at the dense city of wireless environment complexity, because urban construction makes communication environment often change (emerging as new high building) or system upgrade makes antenna for base station may need frequent adjustment.Though existing electrical tilt antenna has the angle of declination regulatory function, but can't accomplish accurately to cover according to the target of actual environment to dense city under complex environment.
Existing antenna for base station mostly is linear array antenna, the synthetic influence that mainly is subjected to 4 factors of its directional diagram: power level and phase place that the directional diagram of radiating element, the arrangement mode of radiating element, radiating element distribute.The parameter that influences antenna pattern that need consider during the array of designs antenna has the directional diagram of unit radiation, the spacing between the unit, the power-division ratios between the unit and phase difference, design the compound direction figure that reaches certain specific character and realize, but problem is to need the adjusting parameter a lot of by regulating these parameters.Single array antenna will realize that particular orientation figure difficulty is bigger.
Summary of the invention
The objective of the invention is provides a kind of antenna figuration system and shaping method of communication base station in order to solve a prior art difficult problem, is characterized in that the figuration process is simple, can solve the base station signal covering problem fast and effectively.
