Description
Technical field
The utility model belongs to antenna technical field, in particular to a antenna of Bluetooth headset.
Background technique
Antenna is the component for being used to emit or receive electromagnetic wave in wireless device, uses electromagnetic waves to setting for transmitting information
It is standby, it is necessary to work by antenna, therefore antenna is widely used in radio communication, broadcast, TV, radar, leads
The fields such as boat, electronic countermeasure, remote sensing, astronomy, in terms of earphone, using it is more be antenna of Bluetooth headset.
There are many antenna of Bluetooth headset of structure currently on the market, wherein having onboard monopole antenna, onboard reversed F-typed day
Line, conducting wire monopole antenna, FPC antenna, ceramic antenna etc..With the development of the society, the continuous promotion of people's living standard,
Requirement of the people to bluetooth headset not only meets functionally, also proposes higher and higher standard to the appearance of bluetooth headset
It is required that so that bluetooth headset increasingly tends to minimize.Since the shape of bluetooth headset is more and more small and exquisite, so that bluetooth headset
Inner space accordingly leaves the design space of Bluetooth antenna for regard to smaller and smaller, Antenna Design is equal in the prior art with regard to smaller and smaller
Using independent antenna element, single antenna design is in one plane carried out, certain space is occupied, it is at high cost.
Utility model content
The purpose of the utility model is to provide one kind to occupy little space, antenna of Bluetooth headset at low cost.
The technical solution of the utility model are as follows: provide a kind of antenna of Bluetooth headset, the pcb board including being at least superimposed on two layers carries
Route, the PCB circuit board are equipped with the etching tinsel conductor for receiving and emitting Bluetooth RF signal, different layers PCB route
Etching tinsel conductor on plate realizes that string layer, the route via hole are single-point or more by the route via hole in each layer PCB circuit board
Point.
Preferably, the PCB circuit board is superimposed with six layers altogether, is from top to bottom followed successively by surface layer, the first ground plane, second connects
Stratum, the 4th layer, third ground plane, bottom.
Preferably, the PCB circuit board of the surface layer and bottom is equipped with etching tinsel conductor.
Preferably, the route via hole in each layer PCB circuit board, which is being formed by get lines crossed, two, difference of getting lines crossed described in two
Etching tinsel conductor end ipsilateral in the PCB circuit board of the surface layer and bottom is connected.
The utility model has the beneficial effects that antenna of Bluetooth headset structure assist side space provided by the utility model is limited
In the case where, method is carried using PCB circuit board, using string layer single-point or Mulit-point Connection mode, inside and outside 2 layers and multilayer circuit board
Layer, the receiving and transmitting of Bluetooth RF signal are reached using the copper sheet of etching, using little space, reaches high effect at low cost
The purpose of Bluetooth antenna design.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model antenna of Bluetooth headset.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing:
Refering to Figure 1, the antenna of Bluetooth headset of the present embodiment, the onboard route of PCB including being at least superimposed on two layers,
The PCB circuit board is equipped with the etching tinsel conductor (61,101) for receiving and emitting Bluetooth RF signal, different layers PCB line
Etching tinsel conductor (61,101) on the plate of road realizes string layer, the route via hole by the route via hole in each layer PCB circuit board
For single-point or multiple spot.
The PCB circuit board is superimposed with six layers altogether, is from top to bottom followed successively by surface layer 71, the first ground plane 72, second ground connection
Layer 73, the 4th layer 74, third ground plane 75, bottom 76.
The PCB circuit board of the surface layer 71 and bottom 72 is equipped with etching tinsel conductor (61,101).
Route via hole in each layer PCB circuit board, which is being formed by get lines crossed, 110 is having two, 110 difference of getting lines crossed described in two
Etching tinsel conductor (61,101) end ipsilateral in the PCB circuit board of the surface layer and bottom is connected.
The present embodiment in PCB circuit board by being arranged etching tinsel conductor as the day received with transmitting Bluetooth RF signal
Line takes full advantage of limited space, takes up little area instead of independent antenna cell design, bluetooth headset can be made to meet shape
Small and exquisite requirement, and the etching tinsel conductor in the present embodiment is the double-deck onboard structure, it is more onboard than single layer more to save space.
The above is only the preferred embodiment of the present invention, it is all done according to the utility model claims range it is equal
Deng variation and modification, it should all belong to the covering scope of the utility model claims.
