Abstract
An antenna structure of a mobile phone includes an internal antenna and an external antenna as well as a RF circuit, is characterized in that the internal antenna and the external antenna are connected with the RF circuit through a switch circuit like an electric switch or a switch mechanism like a single single-pole double throw mechanical switch or a RF switch joint; the external antenna is an external sleeve antenna or an ordinary external antenna or a coaxial external antenna playing the role of prolonging. An external sleeve antenna is designed into a selective accessory of a moving terminal; the external sleeve antenna is not mounted on the moving terminal; the moving terminal receives and sends wireless signals directly through the internal antenna, thus leading the moving terminal to meet the requirement of miniaturization and beauty; the external sleeve antenna with high performance is mounted in a weak signal area or carrying out non-voice date services; thereby improving the communication quality, the data transmission speed and the using time of the battery of the moving terminal as well as reducing the effects to a human body emitted by the moving terminal.
Description
Technical field
The utility model relates to a kind of radio signal transmission parts of portable terminal, belongs to the radio frequency class antenna element of mobile phone.
Technical background
Mobile communication develops fast, and wireless voice and data service have been the periodic traffic business that most people can both afford to consume, and the coverage rate of wireless network also is unprecedented growth.However, there are some places still can not finely satisfy normal communication of mobile terminal requirement such as its network quality of remote rural area; The demand of present in addition portable terminal miniaturization and attractive in appearanceization, the antenna of portable terminal adopts built-in or external monopole antenna usually, these antenna is all with the ground of the mobile terminal circuit plate negative pole as antenna, antenna performance is subjected to the influence of staff and head bigger, and possibility just can not proper communication in the area of network difference.
In the relatively poor area of some wireless networks, promptly enable normal communication, the transmitting power of its mobile phone and power consumption also can be bigger, and electromagnetic wave strengthens the radiation meeting of human body thereupon, and also can reduce the service time of battery.
In addition, wireless data service comes into vogue, and as GPRS, EDGE and 3G, the battery of its message transmission rate and portable terminal all follows the quality of wireless network directly related service time.
If mobile terminal configuration is a kind of high performance antenna, be the equal of quality and the wireless transmission environment that has improved wireless network from another angle, thereby make more area can enjoy the wireless service of high-quality better, this can be a more significant thing.
A kind of traditional external sleeve antenna that is similar to dipole, its sleeve is equivalent to the negative pole of antenna, and the feed coaxial line of antenna enters the other end of sleeve from barrel end, and promptly the centre of entire antenna links to each other with the positive pole of antenna; The effect of the double again chokes cover of sleeve stops the electric current on the antenna negative pole to pass through the ground that the feed coaxial line flows into circuit board of mobile phone.The major advantage of this antenna is: the radiation efficiency height of antenna, and the transmitting-receiving ability is strong; Independent antenna negative pole is arranged, can be and antenna performance descends much because of holding on mobile phone, antenna performance is insensitive to the environment of mobile phone circuit panel area; The point that electromagenetic wave radiation is the strongest on the antenna is away from circuit board of mobile phone, and is less to the radiation of human body.This high performance external sleeve antenna, its disadvantage is that size is big, does not meet the requirement of miniaturization and attractive in appearanceization, carries and use inconvenience, a lot of occasions or a lot of user do not have this high performance demand.
The utility model content
Technical problem to be solved in the utility model is exactly the antenna structure that a kind of mobile phone is provided at the described contradiction of background technology, and it can be maximized favourable factors and minimized unfavourable ones in conjunction with the advantage separately of built-in aerial and external antenna, and easy to use.
The utility model realizes that the technical scheme of goal of the invention is such: a kind of antenna structure of mobile phone, it includes built-in aerial and external antenna and radio circuit, it is characterized in that described built-in aerial is connected with radio circuit by switching mechanism or commutation circuit with external antenna.
Preferably, described external antenna is external sleeve antenna, or general external antenna, or external one section external antenna that plays the coaxial line of prolongation effect.
On the one hand, described switching mechanism is the radio-frequency (RF) switch joint that independent single-pole double throw mechanical switch or single-pole double throw mechanical switch and external antenna interface are integrated.
On the other hand, described commutation circuit can be the electronic switch that switches between built-in aerial pattern, the external antenna pattern.
As improvement, described radio-frequency (RF) switch joint is that built-in aerial feedback point is connected with radio frequency signal transmission line, radio frequency signal transmission line and sheet metal weld together, external antenna coaxial line joint inner wire compressing metal spring sheet, make the metal spring sheet conflict with sheet metal or separate, one end of metal spring sheet and another radio frequency signal transmission line welds together, the other end of another radio frequency signal transmission line is communicated with radio-frequency (RF) transmit-receive circuit, external antenna coaxial line joint inner wire is connected with radio-frequency (RF) coaxial line inner wire, external antenna coaxial line joint outer conductor is connected with radio-frequency (RF) coaxial line outer conductor, weld together external antenna and external antenna coaxial line joint inner wire by the metallic sheath of band spring leaf and the ground of circuit board of mobile phone, external antenna coaxial line joint outer conductor connects.
Further improve, the metallic sheath of described sheet metal, metal spring sheet and band spring leaf becomes one by plastic injection-moulded, is assembled into complete radio-frequency (RF) switch joint.
At last, described radio-frequency (RF) switch joint is welded on circuit board of mobile phone by the surface mounted technology of SMT.
Described mobile phone is all types of mobile terminal devices that comprise 2G, 2.5G, 2.75G, 3G or 4G.
Compared with prior art, advantage of the present utility model is: it is designed to this external sleeve antenna the optional accessory of mobile phone, can load onto at any time or lay down according to user's needs, portable terminal can be switched between built-in aerial pattern and external antenna pattern arbitrarily.Under default situations, external sleeve antenna is not installed on the mobile phone, and mobile phone is directly by built-in aerial transmitting/receiving wireless signal, i.e. the normal mobile phone of the better appearance that can both accept of most of user; In more weak area of signal such as remote rural area, when perhaps carrying out the non-voice data business by GPS, EDGE, 3G etc., can load onto this high performance external sleeve antenna again at any time, close built-in aerial simultaneously, thereby improve communication quality, message transmission rate and battery of mobile phone service time, and reduce of the radiation of the electromagnetic wave of mobile phone emission human body.Overall construction design is reasonable and practical, and is easy to use, effective.
