Description
Technical field
The present invention relates to a kind of miniature 5G communication base station antennas.
Background technique
With ever-increasing mobile subscriber and terminal quantity, business demand amount also rapid growth, the biography currently disposed
System macro base station can not meet the needs of communication service.The construction of one side macro base station needs a large amount of capital investment, construction
Period is very long, and site resource is limited and addressing requires height.On the other hand, if disposing excessive macro base station, can also to run
The burden of quotient's network optimization and operation greatly improves, or even the possibility for having the network coverage excessive.Conventional macro base station is usually indoors
Ability is weaker in terms of the network coverage, and recently as the continuous improvement of user demand, indoor and outdoor shared by house data flow is whole
But in continuous rise, indoor floating resources seem in such a case more lacks the ratio that body flow uses.In addition, due to
Network terminal user distribution over time and space is simultaneously uneven, this results in telephone traffic flowing indoors and the crowd is dense
Region can cause tidal effect, while propose more stern challenge to conventional macro base station.
Low-power consumption, the small base station easily disposed (Small Cell) just come into being in this case, become improvement hot spot
Network, the effective means for improving network capacity and indoor network coverage.It is easy that small base station mainly has compared to the advantage of macro base station
It disposes, safeguard the advantage low with lower deployment cost simple, small in size, and can easily be changed according to the demand of specific service environment
Become its overlay area.These features make small base station have better network carrying ability.Small base station deployment is covered in macro base station
Lid blind area and hot spot region have the function of improving the network coverage, so that the growing data traffic demand of user obtains
Meet.In addition, small base station shows the characteristics of plug-and-play the small base station being deployed in indoor environment is easily used to terminal
Family provides the network insertion of higher speed, this just largely solves the problems, such as macro base station, and network signal is poor indoors.
Small base station market is emerged in 3G, has been developed rapidly since appearance, present deployment total amount surmounts comprehensively
Macro base station.In in September, 2007, commercialization is realized in the U.S. in small base station first, and henceforth, Britain, Qatar, Spain, meaning are big
Multiple countries such as benefit are also dedicated to the research of small base station and the deployment of small base station are included in planning, by 2009 in multiple countries
It comes into operation with area.Quantity in June, 2011, the interior small base station 3G disposed of global range reaches 2,300,000, has far surpassed and has worked as
When 3G macro base station Quantity (1,600,000).Ended for the end of the year 2012, the deployment quantity of the small base station in the whole world alreadys exceed 6,400,000,
Wherein Sprint communication common carrier in the U.S. has been built in the world more than 900,000, AT&T group's construction more than 600,000,
Japanese Ruan Yin group has also built about 130,000.It is shown, is ended according to the small base station construction in the whole world in 2016 and project report
In October, 2015, the deployment amount of small base station in the world have reached 13,300,000.External associated mechanisms statistics cut-off before this
To the end of the year 2017, the deployment total amount of small base station reaches 91,000,000 in world wide.
Our times various regions are very high for the research and development temperature of 5G technology, and domestic and international each mainstream standard mechanism has all recognized
The urgency developed to 5G technology at this stage, and formulated relevant 5G research and development plan.From 4G to 5G, user demand is constantly mentioned
Height, indoor and outdoor data service are significantly expanded, and carrier frequency also will be promoted significantly, and conventional macro base station seems more and more powerless and answers
Right, in following 5G epoch, small base station will necessarily become mainstream on a large scale.Have in the key technology of 5G one be called it is highly dense
The purpose of technology of networking, its exploitation is exactly to prepare for any wide-area deployment of following 5G epoch small base station, therefore 5G epoch
Arrival can truly drive the explosion type of small base station to dispose.
Small base station distribution closeness is proportional to flow of the people, and the more local number of base stations of flow of the people will be more, adjacent
The distance between base station is smaller.On the wall of building, on electric pole, automobile platform all may become small base station deployment station
Point, therefore how to ensure that the durability of small base station and service life just seem especially important.This requires we study base station,
Not only to have to the basic function for sending the information such as real-time power consumption from the background, also to have good durability and use
In the service life, this is that the following small base station institute is prerequisite.
Chinese patent CN106917085B discloses a kind of communication base station with automatically cleaning and anti-corrosion effects, including base
It stands ontology, which includes substrate and the hydrophobic erosion resistant coating set on substrate surface, which is to pass through cold spraying
Stuff and other stuff is sprayed to substrate surface formation by technology；The base station ontology has good hydrophobic effect, shows as good
