Description

Mobile phone with built-in antenna {cellular phone of having interior antena}

The present invention relates to an antenna-embedded mobile communication terminal in which an antenna is installed in a cover of a mobile communication terminal such as a cellular phone, a PCS, a PDA, and the like, thereby reducing the overall volume of the mobile communication terminal, making it easy to carry and use.

More specifically, since the volume is reduced by embedding a patterned antenna substrate in the groove formed on the cover surface coupled to the main body of the flip type or folding type mobile communication terminal so as to be open and close. And it relates to an antenna built-in mobile communication terminal for easy storage and to prevent frequent breakage or failure of the exposed antenna.

A mobile communication terminal called a cell phone or a mobile phone is called a PCS or next generation mobile communication (or third generation mobile communication) that can transmit multimedia information such as data or video in the voice communication of the cellular phone that led the era of analog mobile communication. Has been leading the mainstream in the mobile communication market by switching to data communication of digital mobile communication such as IMT-2000.

The data communication described above can be solved by using a mobile communication network for all kinds of information as the mobile internet is developed through a combination with the Internet.

As such, since a single mobile communication terminal can access various kinds of information, the mobile communication terminal has a meaning beyond the device itself, especially for the young generation who can easily access the Internet environment.

As shown in FIG. 1 (a), the flip type terminal is provided with an LCD display window (2) for displaying an operation state according to a plurality of function buttons (1) and a dial (1a) for operation of a call, and a microphone for making a call. (3) and the body portion (5) on which the speaker (4) is mounted, the exposed antenna (7) coupled to the antenna support boss (6) formed integrally behind the body portion (5), and the body portion (5). And a flip 8 hinged to be opened and closed at a side and a battery unit (not shown) detachably coupled to the bottom of the body portion 5.

As shown in FIG. 1 (b), the foldable terminal includes a plurality of function buttons 1, a dial 1a for a call, a microphone 3 formed on the front side, and a battery (not shown) detachable from the back side. A body portion 5 that is possibly coupled, and a holder 8a, which is hinged to the body portion 5 so as to be openable and closed, and on which the speaker 4 and the LCD display window 2 are mounted.

Referring to the use of the above-described mobile communication terminal (for example, a flip type terminal), the function button 1 and the call dial 1a formed on the body 5 by opening the aforementioned flip 8 are described. After touching the corresponding button and pressing the call key, the signal of the mobile phone main body is modulated by CDMA (code division multifle access) method and output as a high frequency signal, which is transmitted to the antenna 7 through a predetermined connection means. Radiated into the air.

The radio signal of the public is transmitted to the main body circuit of the mobile phone through the antenna (7), and then through the demodulation and decoding process to the user through the speaker (4) can be called.

The mobile communication terminal according to the prior art is installed so that the antenna is exposed to the outside of the device body, the volume of the device is increased, which is inconvenient to carry and store the mobile phone, and fixed with an antenna support boss for installing the antenna to protrude outward. As a means is required, the structure for fixing the antenna is complicated, and thus the workability of designing and manufacturing the antenna is inferior.

In addition, as the antenna end is exposed to the outside, it is often damaged or broken due to contact with external obstacles when it is taken out from the device or when carrying, so the service life of the antenna is shortened. There is a problem.

In addition, as the antenna is exposed from the main body, the external appearance of the terminal is designed and manufactured to maintain a uniform rectangular shape, so that the appearance and aesthetics of the article are poor, so that consumers can easily feel the demonstration and lose the competitiveness of the product. Has

In addition, the cover should be close to the user's ear during the call, harming the user's health due to electromagnetic energy harmful to the human body radiated from the antenna, and the transmitter of the terminal radiates more energy as absorbed by the user's head. The power consumption of the is increased, on the other hand, the receiver has a problem that the sensitivity as much as absorbed falls.

The object of the present invention described above, the built-in antenna to the cover to be opened and closed in the main body, due to the small size of the device is easy to store and carry the mobile phone to provide convenience to the user, no need to take out the load antenna during the call By providing an antenna built-in mobile communication terminal to prevent damage to the antenna.

Another object of the present invention is to protect the user from electromagnetic waves generated during a call, by embedding a patterned antenna connected to the printed circuit board in the main body on the cover surface, as much as the energy absorbed by the user's head An antenna built-in mobile communication terminal is provided to prevent battery power consumption.

It is still another object of the present invention to provide an antenna-embedded mobile communication terminal which can freely design and manufacture the appearance of the existing uniform body by embedding the antenna on the cover surface to improve the appearance and aesthetics of the case. .
