Description
Technical field
The utility model relates to a kind of antenna for mobile phone, especially relates to a kind of unipole antenna of mobile phone communicator.
Background technology
What built-in antenna of mobile phone was general is PIFA and monopole two classes, PIFA (Planar Inverted FAntenna), it is planar inverted-F antenna, it has two shell foots, one is connected with antenna load point on the circuit board, another is connected with antenna ground point on the circuit board, and there is complete ground the antenna below.Monopole, i.e. unipole antenna, it has only a shell foot, be connected with antenna load point on the circuit board, and the antenna below does not have ground and any components and parts fully, is hollow out state fully.
Antenna guarantees that in order to realize good radiation the signal of high-quality guarantees speech quality, needs mobile phone inside can have bigger space to design usually.And mobile phones design now is more and more littler, thin, fashion, and more lay particular emphasis on have high tone quality, can listen to the music, can with the mobile phone of computer synchronous transmission.Like this, the inner space of Antenna Design of giving of mobile phone is just more and more littler, and the environment of antenna becomes more and more abominable.For this rugged environment of alleviation that can be suitable, generally can do hollow out on the circuit board of mobile phone handles, but because the needs of fabric swatch or ID design, all can not provide very desirable hollow out zone (not having ground and any components and parts) under a lot of situations, such as hollow out zone, antenna below can be taken by components and parts such as USB interface, earphone interfaces.Under these circumstances,, interfere with circuit and components and parts on the mobile phone easily, introduce the spuious problem of mobile phone, thereby cause frequent call drop, problem that can not proper communication because the PIFA antenna can produce secondary, three inferior multiple harmonics.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of unipole antenna of mobile phone communicator that suppresses the harmonic wave of antenna for mobile phone, the generation of avoiding the spuious problem of mobile phone, raising speech quality for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of unipole antenna of mobile phone communicator, comprise components and parts, circuit board, described components and parts comprise motor, receiver, microphone, USB interface, earphone interface, charger interface, loudspeaker, described circuit board is a part hollow out state, described components and parts are located at the openwork part of circuit board, it is characterized in that, also comprise antenna, the matching element that is used, described circuit board is provided with the antenna load point, and described antenna is connected with antenna load point on the circuit board.
Described antenna is a unipole antenna.
Described unipole antenna comprises shell foot, aerial radiation main body, and this aerial radiation main body comprises high-frequency branch, low frequency branch.
Described shell foot is connected with antenna load point on the circuit board.
The described matching element that is used comprises electric capacity, inductance.
Described electric capacity and inductance are connected in parallel on the antenna load point place of circuit board.
Compared with prior art, the utlity model has following advantage:
1) can suppress the harmonic wave of antenna for mobile phone;
2) avoid the generation of the spuious problem of mobile phone;
3) improve speech quality.
Description of drawings
Fig. 1 is the structural representation of unipole antenna of the present utility model;
Fig. 2 is for adopting the resonance frequency figure of PIFA antenna;
Fig. 3 is for adopting the resonance frequency figure of the utility model unipole antenna.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of unipole antenna of mobile phone communicator, comprise components and parts, circuit board, described components and parts comprise motor, receiver, microphone, USB interface, earphone interface, charger interface, loudspeaker, described circuit board is a part hollow out state, described components and parts are located at the openwork part of circuit board, also comprise antenna, the matching element that is used, described circuit board is provided with the antenna load point, and described antenna is connected with antenna load point on the circuit board.As shown in Figure 1, be the monopole antenna structure schematic diagram, wherein 10 is shell foot, is connected with antenna load point on the circuit board.20～60 belong to the aerial radiation main body, and 30,40 is high-frequency branch, the resonance length of major control DCS1800; 20,50,60 is low frequency branch, the resonance length of major control GSM900.
As shown in Figure 2, adopt the PIFA antenna, with two shell foots of antenna respectively with circuit board on the feedback point be connected with earth point.From the figure as can be seen, antenna not only has two resonance at our needed communication frequency band, wherein the required frequency range of communication be GSM900 (880～960MHz), DCS1800 (1710～1880MHz), and the more high band outside our required frequency band still has two bigger resonance, corresponding to 5 on the figure, 6 two and 7,8 two points, can find that from above frequency points corresponding these four frequencies are the frequency multiplication point of GSM900, DCS1800 just.Because these two harmonic waves are bigger, can exert an influence to circuit board, thereby can cause the spuious problem of mobile phone, have influence on the normal talking of mobile phone.
As shown in Figure 3, adopt unipole antenna of the present utility model, the shell foot of antenna is connected with feedback point on the circuit board.From the figure as can be seen, antenna only has two resonance at our required communication frequency band, and the more high band outside this frequency band does not have resonance, and it is mild to see that 5 on the figure, compare basically at 6 two and 7,8 two, do not have resonance, a day line harmonics has obtained effective inhibition.
