Description
Technical field
The present invention relates to intelligent watch technical field, more particularly to a kind of intelligent watch and its LTE antenna design side
Method.
Background technology
It is used for the equipment for receiving signal on antenna, i.e. smart machine, such as old-fashioned mobile phone has raised type antenna, and Novel mobile phone is more
Number has been hidden in fuselage.
The RF signal power of radio transmitter output, by feeder line（Cable）Antenna is transported to by antenna with electromagnetic wave
Form radiate.Electromagnetic wave is reached and received behind place, following by antenna（Only receive very little very small part power）, and
Radio receiver is sent to by feeder line.It can be seen that, antenna is the important radio for launching and receiving electromagnetic wave, is not had
There is antenna also just without radio communication.Antenna is various in style, for different frequency, different purposes, different occasions, different requirements
Etc. using under different situations, the present invention adopts according to actual needs LTE antenna.
LTE（Long Term Evolution, the Long Term Evolution of universal mobile communications technology) it is by 3GPP（The 3rd
Generation Partnership Project, third generation partner program）The UMTS for organizing to set up（Universal
Mobile Telecommunications System, UMTS）The Long Term Evolution of technical standard.
LTE system introduces OFDM（Orthogonal Frequency Division Multiplexing, orthogonal frequency
Multiplexing）And MIMO（Multi-Input ＆ Multi-Output, multiple-input and multiple-output）Etc. key technology, frequency spectrum is significantly increased
Efficiency and message transmission rate（In the case of 64QAM, theoretical descending peak transfer rate is 201Mbps to 20M bandwidth 2X2MIMO,
Remove and be about after signaling consumption 150Mbps, but limited according to actual networking and terminal capability, it is considered that down peak magnitude speed
Rate is 100Mbps, upper behavior 50Mbps）, and support that various bandwidth is distributed：1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz and
20MHz etc., and support global main flow 2G/3G frequency range and some newly-increased frequency ranges, thus frequency spectrum distribution is more flexibly, power system capacity and
Covering is also obviously improved.The more flattening of the LTE system network architecture is simplified, and reduces network node and system complexity, from
And Time Delay of Systems is reduced, also reduce network design and maintenance cost.LTE system is supported and other 3GPP system interoperability.
FDD-LTE is divided into according to duplex mode difference LTE system（Frequency Division Duplexing）And TDD-LTE
(Time Division Duplexing), the two technology is differred primarily in that in the physical layer eated dishes without rice or wine（As frame structure, time-division
Design, synchronous etc.）.FDD system is eated dishes without rice or wine up-downgoing using paired UHF band reception and sends data, and TDD system up-downgoing is then
Transmitted on different time slots using identical frequency range, compared with FDD duplex modes, TDD has the higher availability of frequency spectrum.
