Description
Technical field
The invention belongs to communication equipment field, be specifically related to a kind of router.
Background technology
Development along with wireless communication technique, wireless telecommunications system has had more and more higher requirement, in order to satisfy the requirement of communication, existing various wireless router adopts external antenna basically, the surplus energy of the industrial design of very big limits product and mechanism design performance, and external antenna also needs to design impedance matching connector and mechanism's module of adaptation, these connectors and mechanism's module have almost accounted for the cost of whole antenna more than 90 percent, impel the rising of whole wireless router price so whole antenna cost rises.
Sometimes the router data that are limited to antenna are processed many antennas need to be set, many antennas not only have influence on the outward appearance of router in the outer setting of the housing of router, also can be owing to antenna independently protrude from the waste that housing causes the space, these cause greatly inconvenient to people.
Antenna is as radiating element and the receiving device of final radiofrequency signal, and its operating characteristic will directly affect the service behaviour of whole electronic system.The installation of antenna not only needs to consider the shape of antenna itself, the electromagnetic radiation that produces when also needing more to consider the device busy at antenna place, particularly the high-frequency work of central processing unit has produced electromagnetic radiation, this can cause bad impact to antenna reception and transmitted signal, even can therefore cause antenna to work, therefore, the placement of antenna is to need the expensive time to consider and checking in electronic system.
The important indicators such as the size of existing antenna, bandwidth, gain but have been subject to the restriction (gain margin under the fixed dimension, bandwidth limit etc.) of basic physical principle.The basic principle of these index limit so that the miniaturization technology difficulty of antenna considerably beyond other device, and because the complexity of the electromagnetic field analysis of radio-frequency devices, approaching these limiting values all becomes huge technological challenge.
The Radiation work frequency of traditional antenna directly and the size positive correlation of antenna, the area positive correlation of bandwidth and antenna is so that the design of antenna needs the physical length of half-wavelength usually.In some more complicated electronic systems, need to design by the impedance matching network outside the feed antenna forehead.But the increase that impedance matching network is extra the feeder line design of electronic system, increased radio system area simultaneously matching network also introduced many energy losses, be difficult to satisfy the requirement of system design of low-power consumption.Thereby the function of antenna, size become the wireless router reduced volume, reduce the technical bottleneck of cost.
Summary of the invention
