Abstract
The present invention discloses a handset antenna in hidden type. The said antenna, including the grounding part, the metal plate and the wire, is installed inside the handset case of the mobile phone. The grounding part is an electric slice. The metal plate, possessing certain area suitable for inducing the electromagnetic wave signal in high frequency, is connected to the grounding part electrically. The wire, presenting itself in buckling shape suitable for inducing the electromagnetic wave signal in low frequency, is connected to the grounding part electrically. Thus, the length of the invented antenna can be reduced and accomodated in limited space inside handset case, providing the functions of receiving signals with two frequencies of electromagnetic wave and making the handset become light, thin smallish.
Description
The present invention is about a kind of hidden antenna for mobile phone, particularly a kind of entire length can the reduction with the antenna in the hand set machine shell that is suitable for inserting original mobile phone, and then make mobile phone become the integral outer appearance that tool not exposes antenna.
Because the convenience that uses the wireless communication technique of electromagnetic wave transmitting signals to have in the use, make mobile phone become a kind of communication product of quite popularizing in the use, and owing to use the event of electromagnetic wave transmitting signals, therefore the antenna configuration in order to the induced electricity magnetic wave is to be device necessary in the mobile phone, antenna configuration with general now mobile phone handsets, the overwhelming majority is a kind of antenna configuration of exposed conveying appliance, be that its antenna is the protruding outside that is exposed at hand set machine shell, in order to receive or the launching electromagnetic wave signal.
As shown in Figure 1, be a kind of exposed in order to launch and to receive the helical antenna of two kinds of wave frequency signals, it generally has one and is the hollow short cylinder and can be screwed together in carrier 10 on the mobile phone, then accommodate a shape antenna 11 of reeling in the shape of a spiral in the carrier 10, make the coiling of antenna 11 be formed with a dense curling part 111 and a distant curling part 112, make that dense curling part 111 can be in order to the electromagnetic wave of induction low-frequency signal, distant curling part 112 then can reach the purpose that is applicable to dual-band mobile phone whereby in order to the electromagnetic wave of induction of high frequency signal.
Again as shown in Figures 2 and 3, be that another exposedly can and receive the unipole antenna of two kinds of wave frequency signals in order to emission, it also has one and is short cylinder and can be screwed together in carrier 20 on the mobile phone, all sides of carrier then are provided with an antenna 21, and antenna 21 is a film like and design has the metal induction line, it launches the back and has a high frequency region 211 and the low frequency range 212 in order to the induction low-frequency signal in order to the induction of high frequency signal as Fig. 3, makes this kind unipole antenna also can reach the purpose that is applicable to dual-band mobile phone.
Yet, with above-mentioned exposed conveying appliance antenna configuration, be exposed to outside the hand set machine shell because of it is protruding, has the shortcoming that is subjected to the foreign object collision easily and produces bending, fracture in the use, for mobile phone moulded, the antenna of its protruding dew also influences integral aesthetic property in addition, therefore has more and more many mobile phones to adopt concealed antenna configuration, and antenna is arranged at hand set machine shell inside, and then keep the attractive in appearance of mobile phone external form.But with above-mentioned exposed conveying appliance antenna configuration, because the antenna overall length is relevant with electromagnetic wavelength, since and mobile phone has the communication frequency of standard, therefore its wavelength is then for fixing, so the length of antenna is certain value naturally, when it is desired to be arranged at the structure that is same as exposed antenna in the hand set machine shell and is hidden, spatial altitude in the then former hand set machine shell often can't hold original antenna configuration, so, one of method is to make hand set machine shell redesign and make its space strengthen, compact market demands run in the opposite direction but this kind done rule and mobile phone, be not a desirable way, thus have only change original antenna structure to be adapted to the space of former hand set machine shell.
Therefore, main purpose of the present invention is to shorten antenna length and be suitable for the antenna configuration of concealed antenna mobile phone providing a kind of.
So, hidden antenna for mobile phone of the present invention be comprise a grounding parts, a metallic plate and a metal wire, with in the hand set machine shell that is installed on a mobile phone.It is one conductive laminar that this grounding parts is.This metallic plate is to be electrically connected at this grounding parts, and it has certain area to be suitable for induction of high frequency electromagnetic wave signal.And this metal wire is to be electrically connected at this grounding parts, and it is bending to be suitable for responding to the low-frequency electromagnetic wave signal.
Other features and advantages of the present invention in the DETAILED DESCRIPTION OF THE PREFERRED of following conjunction with figs., can clearly be understood, in the accompanying drawings:
Fig. 1 is a kind of schematic diagram of exposed antenna of traditional mobile phone.
Fig. 2 is the schematic diagram of the exposed antenna of the traditional mobile phone of another kind.
Fig. 3 is the expansion plane graph of antenna among Fig. 2.
Fig. 4 is the organigram of a preferred embodiment of hidden antenna for mobile phone of the present invention.
Consult Fig. 4, one preferred embodiment of hidden antenna for mobile phone 3 of the present invention is to comprise a grounding parts 31, a metallic plate 32 and a metal wire 33, whole can being contained in the hand set machine shell 4 of a mobile phone, then be provided with a circuit substrate (figure does not show) with radio circuit of handling the electromagnetic wave signal function in the casing 4, make circuit substrate electrically connect with antenna 3.
This grounding parts 31, it generally is a rectangle and has the lamellar of conductive characteristic, can be located at the back of casing 4, so that the characteristic of a circuit ground to be provided.
This metallic plate 32 is to be electrically connected at grounding parts 31, and it has certain area to be suitable for induction of high frequency electromagnetic wave signal.And
This metal wire 33 is to be electrically connected at grounding parts 31, and it is bending to be suitable for responding to the low-frequency electromagnetic wave signal.
During application, mainly be to utilize grounding parts 31 area sizes to make the electric capacity of integrated antenna and inductance value can produce resonance in electromagnetic wavelength two/a period of time, therefore metallic plate 32 can be in order to respond to the high-frequency signals of 1/2nd wavelengths of electromagnetic, the metal wire 33 of utilization bending then can be in order to respond to quarter-wave low-frequency signal in addition, design by metallic plate 32 can make the length of integrated antenna be dwindled, and then integrated antenna can be contained in the limited hand set machine shell 4 in script space, the function that receives two kinds of wave frequency signals simultaneously can be reached, also the compact characteristic of mobile phone can be therefore kept.
The above only is the preferred embodiments of the present invention, can not limit scope of the invention process with this, and all simple equivalent of doing according to claim scope of the present invention and description change and modify, and all should still belong in the scope that patent of the present invention contains.
