Description
Technical field
The invention belongs to radio communication diversity antenna technical field, it is particularly related to wireless communication terminal diversity antenna technology.
Background technology
Along with developing rapidly of radio communication, its number of users increases day by day, and data service constantly increases, and the wireless communication system of single antenna transmitting-receiving is being faced with severe capacity bottleneck test, must further improve current wireless capability of communication system and quality, seek new technical scheme.MIMO (MIMO) technology is one and utilizes multiple radio communication new technology of penetrating with multiple receive antenna, its data streams is separated into the multichannel sub data flow, after modulation, launch simultaneously through different antennas with identical frequency, beyond-the-horizon communication by wireless channel, these parallel sub-streams may arrive receiver by different paths, received by different reception antennas, receiver can merge the incoming wave signal and recover original data stream.Utilize this technology, wireless system can obtain spatial multiplexing gain and diversity gain, and its efficient parallel data pipe has improved the capacity of mimo system.Traditional radio communication theory is considered as multipath transmisstion causing a kind of interference of wireless signal decline always, and the MIMO technology sends simultaneously and receives by adopting many antennas, can make full use of multipath transmisstion, just as on original frequency range, having set up a plurality of non-interfering, parallel subchannels, and the advanced multiuser detection of utilization, simultaneously transmit user data accurately and efficiently, thereby significantly improve the capacity and the quality of Radio Link.Therefore, the MIMO technology is the important channel of realizing the wireless communication system high-speed transfer.
Yet, the jumbo acquisition of mimo system with fading signal uncorrelated or low relevant be prerequisite, promptly require to have abundant electromagnetic scattering body in the wireless communications environment and many antenna elements spacing enough big.Around the user terminal of wireless mobile communications, there is a large amount of scattering objects, this makes that the expansion of radio magnetic wave signal angle is very big, only needs the antenna element spacing of less (less than a wavelength) just to be enough to obtain lower correlation.But in practice, user terminal is miniaturization day by day, and the spacing of its many antenna elements may still have problems for the implementation space diversity.
And, wireless communication user is using terminal (as mobile phone, portable phone etc.) time, its terminal antenna may be in an angle at random, the polarised direction that is antenna may be at random, and electromagnetic wave is when propagating in wireless channel, there be reversing of polarised direction, promptly arriving the polarization of electromagnetic wave of reception antenna and the polarised direction of reception antenna does not match, therefore, in wireless transmission, except the multipath fading that multipath transmisstion causes, also there is the polarization mismatch decline, so received signal intensity is very sensitive to the orientation of user terminal.
In addition, terminal antenna is the problem that the user is concerned about very much to the radiation injury of human body.Conventional omnidirectional antenna has caused people's extensive dispute to the radiation injury of user's brain.
The conventional design of antenna does not have the design of many antenna elements, the design of antagonism polarization mismatch of the above-mentioned low correlation of fine solution and reduces problems such as radiation injury to the terminal use, because these have proposed high requirement, the particularly layout of the many antennas of terminal and design to many Antenna Design and diversity antenna design.
At the United States Patent (USP) 6 of authorizing people such as Iwai, 670, among 925 B2 " inversed F-shaped antenna unit and the portable radio communication device that adopts inverse-F antenna " (Inverted F-type antenna apparatus and portable radio communicationsapparatus provided with the inverted F-type antenna apparatus), a kind of method and apparatus that makes up the inverse-F antenna unit is disclosed.But this invention only provides the design of antenna element, does not have to consider to be used for the problem of many Antenna Design.At the United States Patent (USP) 5 of authorizing people such as Stephen, 486, showed a kind of quadrature feed paster antenna that is used for portable terminal in 836 " isolating and the method for diversity to provide " with double-fed rectangular patch antenna system and wireless device, but this antenna two way feed is respectively applied for one and receives one, can't obtain sufficient diversity, thereby the raising of communication quality is limited.At the United States Patent (USP) 6 of authorizing people such as Michael, 545, among 642 B1 " antenna/button assembly and have the mobile terminals of this assembly " single card chip antenna a kind of GPS of being used for location, that place the panel button below has been described, thereby the ground plate of this antenna is effectively enlarged because of always linking to each other with system, and radiation/reception is improved.But this invention is not that its scheme can't combine with the MIMO processing module at the design of MIMO mobile communication.At the United States Patent (USP) 6 of authorizing people such as Smith, 426, among 723 B1 " antenna arrangement of MIMO communication system " (Antenna arrangement for multiple input multiple output communications systems), the antenna arrangement of the disclosed MIMO of being used for communication system only is suitable for large-scale terminal, and the antenna element number is too much, be not suitable for being used for Miniature Terminal (such as, be used for the hand-held set of radio communication).In authorizing the Chinese patent CN 1411158A of the former Shang Zi of plum etc. " diversity antenna and use its Wireless Telecom Equipment ", the diversity antenna design of announcement is unsuitable for terminal applies, is unsuitable for the many Antenna Design of hand-held set especially.Open among the 2000-353911 the Japan Patent spy who authorizes straight Jiang Bo, described many Antenna Design of being carried out at the down turnover cover mobile terminals.But each antenna channel is to select according to qualifications by switch according to the virtual condition of using, and the demand of communicating by letter with MIMO is also inequality, its improvement of obtainable communication quality also be limited.In authorizing the flat 3-280625 of Japan Patent " portable wireless communication machine " of tail woods show one, provided the multi-antenna diversity placement scheme that is used for the hand-held mobile communications terminal, but this invention not on many antenna foundations to the number on antenna ground, further optimization is set, its polarization diversity effect also remains further to be improved simultaneously.
