Description
Technical field
The invention belongs to communication equipment fields, and in particular to a kind of router.
Background technology
With the development of wireless communication technique, wireless telecommunications system has increasingly higher demands, in order to meet communication
It is required that existing various wireless routers substantially use external antenna, industrial design and the mechanism design of product are greatly limited
The surplus energy of performance, and external antenna also need to design adapt to impedance-matching connectors and mechanism module, these connectors and
Mechanism module almost accounts for the cost of entire antenna 90 or more percent, so entire antenna cost increase promotes entirely wirelessly
The rising of router price.
Sometimes router is limited to the data processing of antenna and needs that more antennas, shell of the more antennas in router is arranged
It is outer that the appearance for not only influencing router is set, can also be due to the independent waste for protruding from shell and causing space of antenna, this
It is greatly inconvenient to be caused a bit to people.
Radiating element and receiving device of the antenna as final radiofrequency signal, working characteristics will directly affect entire electronics
The working performance of system.The installation of antenna not only needs to consider the shape of antenna itself, it is also necessary to which more consideration is given to where antenna
The electromagnetic radiation that generates at work of device, the high-frequency work of especially central processing unit produces electromagnetic radiation, this can pair
Antenna sends and receivees signal and causes undesirable influence, or even therefore antenna can be caused to can not work normally, therefore, in Department of Electronics
The placement of antenna is to need to take a lot of time consideration and verification in system.
The important indicators such as size, bandwidth, the gain of existing antenna but receive the limitation (fixed dimension of basic physical principle
Under gain margin, bandwidth limit etc.).The basic principle of these index limit makes the miniaturization technology difficulty of antenna much super
It has crossed other devices, and the complexity of the electromagnetic field analysis due to radio-frequency devices, has approached these limiting values all and become and is 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,
So that the design of antenna usually requires the physical length of half-wavelength.In some increasingly complex electronic systems, need in feed-in
Impedance matching network design outside antenna forehead.But the additional feeder line design for increasing electronic system of impedance matching network increases
Matching network also introduces many energy losses to the area of big radio frequency system simultaneously, it is difficult to meet the system design of low-power consumption
It is required that.Thus, function, the size of antenna become the technical bottleneck that wireless router reduces volume, reduces cost.
