Description

Dual folder type mobile communication terminal with built-in antenna {DUAL FOLDER TYPE MOBILE PHONE}

The present invention relates to a dual-folder type mobile communication terminal having a built-in antenna, and more particularly, a built-in type which improves portability of a terminal and maximizes a radio wave range by embedding an antenna in the hinge coupling part to embed the antenna in the terminal. A dual folder type mobile communication terminal provided with an antenna.

In general, an exposed antenna 1 installed in a conventional dual folder type mobile communication terminal protrudes a predetermined length from the top of the main body 20 coupled with the folder 10 and the hinge device 30 as shown in FIG. There is installation.

As shown in FIG. 2, the exposed antenna 1 is connected to an RF board 41 mounted on a printed circuit board 40 embedded in the main body 20 by a feed line 42. .

Therefore, since the radio wave is transmitted and received through the antenna 1, it is possible to make a telephone call wirelessly with the other party.

However, since the exposed antenna 1 is exposed to the outside of the terminal, the terminal may be broken or damaged while being used, and when the terminal is placed in a pocket or the like, the terminal may be lying on its side or pulled out quickly to use the antenna ( 1) There are inconveniences in use and portability, such as the site is caught in the pocket, causing inconvenience to the user.

Accordingly, the present invention has been made in view of such a conventional problem, and in particular, the antenna is built into the terminal to improve the portability of the terminal, and the antenna of the hinge coupling part is built into the antenna by the built-in antenna. The purpose of the present invention is not to reduce the space efficiency of the components installed therein, and to modify the shape of a predetermined portion of the terminal proximate the hinge coupling portion to maximize the radiation range of the antenna installed in the hinge coupling portion.

In order to achieve the above object, the present invention provides a main body having a first hinge arm and a second hinge arm protruding from a printed circuit board mounted with RF-bolzes and spaced at left and right sides of the upper end, and the first hinge arm and the first hinge arm. A dual folder type mobile communication terminal comprising a center hinge arm, which is formed at both ends of a second hinge arm, and a folder protruding from a lower end thereof, wherein the center hinge arm is built on a first hinge arm or a second hinge arm of the main body and electrically connected to the RF board. It provides a dual-folder mobile communication terminal having a built-in antenna, characterized in that it comprises an antenna connected to.

In addition, the upper end of the main body and the lower end of the folder is formed in a predetermined inclined surface outward to maximize the electric field emission range of the antenna embedded in the first and second hinge arms.

When described in detail with reference to Figures 3, 4, 5 attached to the configuration and the embodiment of the present invention.

3 is a perspective view of an antenna-embedded dual folder type mobile communication terminal according to the present invention, and FIG. 4 is a schematic side view of an antenna-embedded dual folder type mobile communication terminal according to the present invention, and FIG. 5 is an antenna-embedded dual folder according to the present invention. Perspective view of an antenna embedded in a mobile communication terminal.

As shown in FIG. 3, the antenna-embedded dual folder 120 type mobile communication terminal 100 according to the present invention has a first side hinge arm 111 and a second side hinge arm 112 at regular intervals to the left and right sides of the top. ) And a center hinge arm 121 whose both ends are formed on the first side hinge arm 111 and the second side hinge arm 112 are protruding from the lower portion 120. It is composed.

The main body 110 includes a printed circuit board 113 on which an RF mode 114 is mounted, and an antenna 115 is embedded in the first and second side hinge arms 111 and 112.

In addition, the antenna 115 is electrically connected to the RF mode 114 through a feed line.

The antenna 115 is formed in a coil shape as shown in FIG. 5 to maximize the total length of the antenna 115 when mounted on the first side hinge arm 111 and the second side hinge arm 112. Maximize the sensitivity of radio waves.

According to the present invention configured as described above, the antenna 115 connected to the RF mode 114 and the feed line 116 is axially embedded in the first side hinge arm 111 or the second side hinge arm 112, and the first side By arranging both ends of the center hinge arm 121 at the hinge arm 111 and the second side hinge arm 112, the main body 110 and the folder 120 are hinged to rotate within a predetermined angle.

At this time, the antenna 115 embedded in the first and second side hinge arms 111 and 112 serves to transmit and receive radio waves as in the conventional exposed antenna 1 (see FIG. 1).

Since the antenna 115 is built in this way, when the terminal 100 according to the present invention is carried in a pocket or the like, the portable space can be reduced as compared to the terminal 100 where the antenna 1 is exposed as in the related art.

In addition, by forming the lower end of the folder 120 and the upper end of the main body 110 at an angle to the outside, the radiation range of the antenna 115 is improved compared to the conventional terminal 100.

As described above, the present invention has an effect of reducing portability and storage space compared to a conventional terminal by incorporating an antenna.

In addition, the present invention is formed by inclining the bottom of the folder and the top of the main body at an angle to the outside, thereby improving the radiation range of the antenna compared to the form of the main body and the folder of the existing terminal.

In addition, the present invention has the effect of improving the internal usability of the terminal by embedding the antenna in the empty space.
