Abstract
The utility model aims at providing a method for designing a built-in radio antenna for a mobile telephone. The method comprises the following steps: a flexible printed circuit board (FPC) is taken as the base material of the antenna; and a coppered wire which has the snake shape and square wave shape or combining with the snake shape and the square wave shape on the base material is used for designing the antenna. The flexible printed circuit board has the features that the flexible printed circuit board is flexible, can be made into various shapes, and can just farthest use the space of the mobile telephone, has low design cost and credible use.
Description
Technical field
The utility model relates to a kind of radio antenna that is applied to mobile phone.
Background technology
Universal day by day along with mobile phone, its function development makes rapid progress, and no longer has been only to satisfy wireless communication function, also is the recreation terminal of a feature richness simultaneously.Broadcast receiver is popularized as a tradition, very much, abundant in content wireless media terminal also is integrated into mobile phone, and the mobile phone market share that had radio function in 2008 will reach more than 45%.On the present mobile phone is frequency modulation (FM) broadcast receiver mostly, the receiver frequency range is at 88,000,000 to 108 megahertzes, belong to the medium wave scope, desirable half-wave antenna requires length to reach 1.5 meters, traditional broadcast receiver adopts very long telescopic antenna, and this integrated in portable mobile phone be very difficult, so what mobile phone-broadcast receiver adopted at present is that earphone is as receiver antenna, the deficiency of this mode is must plug in the earphone when listening to broadcast receiver, and radio function just can't use after earphone leaves behind or damages.
The utility model content
At above-mentioned defective, the purpose of this utility model is to provide a kind of radio antenna that is applied to mobile phone.
The technical solution of the utility model is:
A kind of radio antenna that is applied to mobile phone is characterized in that: should be the antenna of base material with the Flexible Printed Circuit, and continuous with the feedback point of cell phone mainboard, place the mobile phone internal body.
Walk the coppered wire that snakelike or square waveform or above-mentioned both waveforms combine on the described Flexible Printed Circuit.
The line of waveform and the distance between the line are more than or equal to 1 millimeter on the described Flexible Printed Circuit.
Antenna can pass through welding manner or screw fixation method with being connected of cell phone mainboard feedback point.
This antenna links to each other with cell phone mainboard feedback point by T type match circuit.
This antenna length is more than or equal to 9 centimetres
This antenna length optimum value is 1.5 meters.
This antenna with peripheral metal or conductor more than or equal to 3 centimetres.
The utility model uses on the Flexible Printed Circuit and walks the built-in antenna of mobile phone of coppered wire as antenna radiator, substituted existing earphone receiver antenna, save cost, the convenient use, stopped because earphone with the situation that can't receive broadcasting, and is pullled the probability that damages owing to built-in characteristic has also reduced to be impacted.In addition, the soft circuit that antenna adopts because of its plate quality softness, can be made into different shape, can farthest utilize narrow and small and irregular space in the mobile phone, comparatively good sound quality is provided.
Description of drawings
Below, be described with reference to the accompanying drawings.
Fig. 1 is the square waveform antenna diagram.
Fig. 2 is snakelike antenna diagram.
Fig. 3 built-in aerial design example figure.
Description of reference numerals: 1 indication dash area is for putting wave antenna feedback point among Fig. 1, and 1 indication dash area is for putting wave antenna feedback point among Fig. 2, and 1 is loud speaker among the figure three, and 2 is battery.
Embodiment
This specific embodiment as shown in Figure 3, antenna has adopted the snakelike and design square waveform combination.In mobile phone, the antenna that with the Flexible Printed Circuit is base material is continuous with the feedback point of cell phone mainboard by welding manner (or screw fixation method), before the feedback point T type match circuit is set, Flexible Printed Circuit go forward half section narrower between part between battery and loud speaker walk square waveform, part between the second half section broad between mobile phone sidewall and battery is walked snakelike, and soft line plate is by Kaifeng groove in the casing or directly paste fixing.The signal input pin of the as far as possible close receiver circuit of antenna feed point.Before use, by T type match circuit, the resonance point of antenna is adjusted according to actual result.
Antenna in the foregoing description also can only adopt square waveform antenna as shown in Figure 1, or only adopts snakelike antenna as shown in Figure 2.
The above is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should be technology category of the present invention.
