Third-generation mobile communication technology (5G) is come into being.It is wirelessly connected and increasingly higher demands is proposed to multiband aerial, while is modern
Requirement of the communication equipment to miniaturization is also harsher, therefore small design multiband aerial becomes when previous new development
Trend.Planar printed antenna has obtained academia and industry due to its lower cost, lighter quality and preferable performance
Vast concern.
However 2G, 3G, 4G system can't be substituted at once at present, but several communications within the quite a long time
System will coexist, this just brings new requirement to the design of wireless communication system, it is necessary to can support multiple frequency ranges simultaneously.
Current simplest scheme is exactly to meet the requirement of multisystem using multiple and different dual-mode antennas.However, this scheme was both
The compatibility for being unfavorable for system is also unfavorable for the layout of antenna, and manufacturing cost is relatively high.Solution best at present is to set
Multisystem shared antenna is counted, that is, provides service simultaneously with a secondary multiband aerial for multisystem.The advantages of this design scheme
It is that can effectively reduce antenna amount, reduces production cost, while the interference of antenna system can be reduced again.Polyphyly altogether
In the case where depositing, it is necessary to multiband aerial is designed, to meet the requirements.
With reaching its maturity for wearable technology, various wearable products pour in the life of ordinary people on a large scale.It can wear
Wear equipment and refer to and carry out intelligent allocation using the wearable technology wearing daily to people, by various sensings, identification, connection and
The technologies such as cloud service are implanted in the daily wearing such as glasses, wrist-watch, bracelet, clothes, footgear of people.Wearable device is being transported
The numerous areas such as dynamic health, amusement and leisure, medical treatment auxiliary are widely used.More adhesion types and implanted are worn
It wears equipment to develop constantly, the development for having benefited from minimizing wearable antenna technology of these technologies.Wearable electronic
One of significant challenge of equipment is to realize flexible, ubiquitous, firm and inexpensive wearable antenna, while showing again
It is similar to the radio-frequency performance of rigid copper out.
Summary of the invention
