Description
Technical field
This utility model relates to wireless communication technology field, particularly relates to a kind of miniaturization for 5G mobile communication
Antenna.
Background technology
The research of the 5th third-generation mobile communication (5G) technology launches the most in high gear, 2015 years world without
The primary subject under discussion of line TV university meeting (WRC-15) is exactly that the 5th Generation Mobile Communication System finds frequency spectrum resource in below 6GHz frequency range.
5G frequency planning is made up of low-frequency range and high band, and wherein low-frequency range (below 6GHz) is due to reasons such as good propagation characteristics still
Being so the core frequency band of 5G system, emphasis solves the Consumer's Experience that 5G is ubiquitous, and the application scenarios such as Internet of Things, car networking
Demand；High band (more than 6GHz) is 5G important supplement frequency range, is mainly used in meeting the need such as the mobile broadband service that 5G strengthens
Ask.Whole world concordance is that the generally consideration of 5G frequency range to be studied and following 5G frequency planning are chosen in current every country and area
Important evidence, also will be the important prerequisite of 5G standard globalization.ITU expects the year two thousand twenty and will have lacking of up to 880MHz frequency spectrum
Mouthful, in the TDD licence plate that the whole world has been provided, based on 3.5GHz frequency range (3.4-3.8GHz) more than 50%.3.5GHz can carry
For up to 400MHz frequency spectrum.Along with the further promotion of WRC-15, other 400MHz frequency spectrum (3.8-even can be discharged
4.2GHz).Following IMT potential candidate frequency range the most also include 3300-3400MHz, 4400-4500MHz, 4800-4990MHz with
And 5100-5600MHz etc..
As the extensive MIMO technology of 5G core technology, its basic feature is to configure large number of antenna in base station side
Array (from tens to hundreds of), utilizes space division multiple access (SDMA) principle, services multiple user simultaneously.Due to large-scale antenna array
The vast array gain brought and interference mitigation gains so that spectrum efficiency has obtained great lifting.
Along with the increase of number of antennas, the area that antenna occupies increases, and this just installs to antenna and base station selection brings
Trouble.Such as base station side is configured with 128 antennas, if arrangement is in uniform linear array, antenna distance is half-wavelength, at center
When carrier frequency is 3GHz, a length of 5 centimetres of half-wave, then a length of 6.4 meters of linear array, this is the most unacceptable in engineering.Logical
Cross employing miniature antenna, reduce antenna distance and change aerial array topological structure etc., the thing of aerial array can be reduced
Reason size.But the change of antenna topology, changes channel characteristics therewith, thus affects the performance of signal precoding technology and system
Deng；Antenna distance is less than half-wavelength, and the correlation properties between antenna can be brought to change, and the coupling between antenna increases, and produces
Raw graing lobe, thus affect the performance of system.For linear array, when antenna distance is less than half-wavelength, performance drastically declines.Should
Declining mainly by caused by the dependency of antenna of performance, and antenna coupling does not the most reduce performance, the most enhancing
Energy.And for planar array, when antenna distance is less than 1 times of wavelength, performance the most drastically declines.Same, this performance
Declining and mainly caused by the dependency of antenna, the impact that antenna coupling brings is very little.It can be seen that it is true to reduce antenna distance
Can increase the feasibility of project installation in fact, but can cause the decline of performance, different antennae is put antenna distance simultaneously
Sensitivity is the most different, so combine antenna puts pattern, antenna distance and data transmission method for uplink to systematic function
Impact be one of important research direction.In order to reduce the impact of antenna coupling, it may be considered that select difference between adjacent antenna
The antenna of polarised direction, uses left and right circular polarized antenna or the antenna of positive/negative 45 ° respectively such as adjacent antenna.
Planar equiangular spiral antenna is a kind of more universal broad-band antenna, belongs to frequency-independent antenna series.This antenna energy
Enough have good impedance operator, pattern characteristics and circular polarization characteristics in the widest frequency band, but big in traditional design
Partial volume and size are the biggest.
