Abstract
The utility model relates to a mobile phone antenna, which is characterized in that the mobile phone antenna directly uses the existing metal shell of the mobile phone as an antenna radiation body, the surface of the metal shell is provided with a gap, a signal output by a radio frequency unit is fed into one side of the gap by means of a radio frequency transmission line, the metal shell on the other side of the gap is provided with a grounding point, and the grounding point is electrically connected to the metal ground plane of the mobile phone. Compared with the prior art, the mobile phone antenna provided by the utility model has the advantages that the independent space for the antenna is not needed, the size of the mobile phone is saved, the current popular exterior structure design is matched, the implementation method is simple, and the application prospect of the mobile phone antenna is good in high-frequency sections of more than 2G such as Bluetooth and WIFI (Wireless Fidelity) and the like.
Description
Technical field
The utility model relates to a kind of antenna for mobile phone.
Background technology
Nowadays cell-phone function is abundant day by day, and along with bluetooth, GPS etc. use progressively and popularize, and the antenna that needs is also more and more, just needs to increase an antenna and increase a kind of application function, and these antenna always will occupy certain space in mobile phone inside.But the external dimensions and the inner space of mobile phone are all very limited at present, and particularly people wish that also the volume of mobile phone can be frivolous convenient when pursuing strong functions.Seek a kind of increase application function so press for, increase antenna amount and can not increase the technical scheme of handset size.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of antenna for mobile phone that can not increase the size of mobile phone own at above-mentioned prior art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this antenna for mobile phone, it is characterized in that: this antenna for mobile phone directly utilizes the existing metal face-piece of mobile phone as antenna radiator, surface design one slit at this metal face-piece, the signal of radio frequency unit output is by the one side in the described slit of radio-frequency transmission line feed-in, the metal face-piece of described slit another side is provided with earth point, and this earth point is electrically connected with the metal ground of mobile phone.
If itself have functional slit on the mobile phone metal face-piece, be positioned on the metal face-piece such as loudspeaker, then can directly utilize phonate hole as the slit, feed signals to loudspeaker phonate hole place.
Nowadays the metal shell mobile phone becomes more and more popular, such mobile phone has a larger area metal battery face-piece or other large-area metal housing usually, and the utility model is exactly to utilize metal battery face-piece ready-made in the mobile phone or other large-area metal housing radiant body as antenna for mobile phone.Cut a slit on the surface of this metal battery face-piece, utilize the principle of slot antenna, energy is from the slit feed-in, and electric current intersperses among (being the metal battery face-piece described in the utility model) on the full wafer conductor, and the electric current on direction vertical with long limit, slit on the conductor piece can produce radiation.
The length in slit can determine that jointly the shape in slit can be straight line in conjunction with appearance design and radio frequency debug results, broken line, curve, different shapes such as U font.The length in slit can be determined jointly in conjunction with appearance design and radio frequency debug results, is generally 1/4th of communication signal wavelength and arrives between half.
Compared with prior art, advantage of the present utility model is: adopt antenna for mobile phone scheme of the present utility model, need not to be separately the antenna configurations space, saved the size of mobile phone, cooperated present popular surface structure design, implementation method is simple, special high band such as bluetooth more than 2G, and WIFI etc. have the prospect that well is suitable for.
Description of drawings
Fig. 1 is the structural representation of antenna for mobile phone among the utility model embodiment one.
Fig. 2 is the structural representation of antenna for mobile phone among the utility model embodiment two.
Embodiment
Below in conjunction with the accompanying drawing example the utility model is described in further detail.
Embodiment one:
Antenna for mobile phone as shown in Figure 1, its radiant body directly utilize existing metal battery face-piece 2 in the mobile phone 1, and cut a slit 3 on the surface of this metal battery face-piece.Radio frequency in theory the length in slit be half of communication signal wavelength for good, its actual size and dimension can be debugged and optimizes according to the actual conditions of cell phone appearance design and radio-frequency performance, is generally signal wavelength 1/4th to 1/2nd.Radiofrequency signal is by radio frequency unit 4 outputs, be fed to somewhere, edge, slit by modes such as radio-frequency transmission line 5 bond shell fragments or POGO PIN, the position 6 of signal feed-in can be determined by radio frequency debugging and mobile phone global design, to reach good impedance matching.Signal feed-in point not the metal face-piece of another side in slit on earth point 7 of configuration, be electrically connected the metal ground of earth point 7 and mobile phone by modes such as metal clips or POGO PIN.
Embodiment two:
When if existing mobile phone 1 has loudspeaker 8 below metal face-piece 2, promptly can be by modes such as radio-frequency transmission line 5 bond shell fragments or POGO PIN with the phonate hole 3 of radiofrequency signal feed-in loudspeaker on mobile phone metal face-piece, being about to phonate hole directly uses as the slit, thereby on the metal battery face-piece, produce antenna effect, referring to shown in Figure 2.
Usually the metal face-piece of mobile phone has several places earth point.For this antenna, except the earth point corresponding with signal feed-in point, other earth point quantity is few more, and is far away more with the distance in described slit, and the antenna effect is good more.
This antenna scheme need not to be separately the antenna configurations space, and the size of having saved mobile phone has cooperated present popular surface structure design, and implementation method is simple.Special high band such as bluetooth more than 2G, WIFI etc. have the prospect that well is suitable for.
Claims (2)
1. antenna for mobile phone, it is characterized in that: this antenna for mobile phone directly utilizes the existing metal face-piece of mobile phone as antenna radiator, surface design one slit at this metal face-piece, the signal of radio frequency unit output is by the one side in the described slit of radio-frequency transmission line feed-in, the metal face-piece of described slit another side is provided with earth point, and this earth point is electrically connected with the metal ground of mobile phone.
2. antenna for mobile phone according to claim 1 is characterized in that: the shape in slit linearly or broken line or curve or U font line.
