Patent Application
20060281500
The present invention relates to a mobile telecommunication apparatus (such as a mobile phone), more particularly to an antenna assembly that is employed in the mobile phone and that is compatible with different communication protocols.
Mobile phones, smart phones and PDAs (personal digital assistants) are some of the handy articles that facilitate a busy person of nowadays to accomplish some of his daily works, like noting down the business appointments, tracking the lists of stocks, making simple calculation, storing addresses of the clients, and transmitting e-mails.
Referring to
As illustrated in
The mobile phones of today operate under several communication protocols, such as GSM (Global Sim Mobile), GPS (Global Positioning System), WLAN (Wireless Local Area Network) and etc. The WLAN includes IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and bluetooth protocol, each of which has specific bandwidth and its distinguishing characteristic.
In case, the mobile phone of today is required to be constructed in such a manner to possess multiple functions, such a receiving TV digital signals and sending e-mail. The communication module 10 of the mobile phone 2 should be provided with the antenna assembly adapted to be compatible with the aforesaid four communication protocols. It will require a relatively large amount of space to accommodate four antenna structures in the mobile phone. Since the manufacture of the mobile phone tends toward compact size, it is considerably difficult to construct a versatile antenna assembly under the restricted given space in the mobile phone.
The object of the present invention is to provide a construction design for fabricating an antenna assembly on a flexible base plate such that the antenna assembly can be employed in the mobile phone and the latter can be operated under different communication protocols.
In one aspect of the present invention, an antenna assembly is provided for use in a telecommunication apparatus. The telecommunication apparatus includes a main body provided with a communication module, a cover member for covering the main body, and a battery sandwiched between the cover member and the main body for supplying power source to the communication module. The antenna assembly includes: a base plate adapted to be sandwich between the battery and the cover member; an antenna metal strip unit fabricated on the base plate in order to be sandwiched between the battery and the cover member; an electrical contact unit fabricated on the base plate for establishing electrical communication between the communication module and the antenna metal strip unit; and an etched connecting leg unit for establishing communication between the electrical contact unit and the antenna metal strip unit.
In a second aspect of the present invention, a mobile telecommunication apparatus is provided to include: a main body having a communication module; a cover member for covering the main body; a battery sandwiched between the cover member and the main body for supplying power source to the communication module; and an antenna assembly. The antenna assembly includes: a base plate sandwich between the battery and the cover member, an antenna metal strip unit fabricated on the base plate and sandwiched between the battery and the cover member, an electrical contact unit fabricated on the base plate for establishing electrical communication between the communication module and the antenna metal strip unit, and an etched connecting leg unit for establishing communication between the electrical contact unit and the antenna metal strip unit.
Other features and advantages of this invention will become more apparent in the following detailed description of the preferred embodiment of this invention, with reference to the accompanying drawings, in which:
Referring to
The main body 32 has a communication module 40. The cover member 36 is disposed above for covering the main body 32. The battery 34 is sandwiched between the cover member 36 and the main body 32 for supplying power source to the communication module 40.
Referring to
The protective membrane 50 is disposed between the base plate 42 and the battery 34 for spacing the base plate 42 apart from the battery 34. The main body 32 further includes an electrical connector 54. The battery 34 has a conducting contact unit 52 (including five electrical contacts 53) via which power source of the battery 34 is supplied to the communication module 10. The electrical connector 54 has four antenna-contacting terminals 5402 for coupling with four contacts in the electrical contact unit 46, thereby forming electrical communication between the communication module 40 and the battery 34. In this embodiment, the base plate 42 is made from a flexible substance and is sandwiched between the battery 34 and the cover member 36. Since the flexible base plate 42 is compressible, the latter occupies little space even though its dimension area is relatively large. It is noted that the battery 34 and the electrical connector 54 are provided with a plurality of electrical contacts in order to compatible with the different configuration of the antenna assembly 38. In order to accommodate in the mobile phone of the present invention, each of the antenna metal strips 44a, 44b, 44c and 44d is constructed in a quarter wavelength principle of a transmission frequency.
As shown in
Referring to
To summarize the above paragraphs, the present invention provides a construction design to provide four types antennae on the flexible base plate that is to be accommodated within the restricted space of the mobile phone of the present invention.
While the invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
