본 발명은 내장형 안테나가 구비된 듀얼 폴더형 이동통신 단말기에 관한 것으로서, 더욱 상세하게는, 이동통신 단말기의 폴더 외측면에 근접하도록 안테나를 내장하므로써 이동통신 단말기를 슬림화하고 전자파에 의한 피해를 줄이는 내장형 안테나가 구비된 듀얼 폴더형 이동통신 단말기에 관한 것이다.The present invention relates to a dual clamshell mobile communication terminal provided with a built-in antenna, and more particularly, to reduce the damage caused by electromagnetic waves by slimming the mobile communication terminal by embedding the antenna close to the outer surface of the folder of the mobile communication terminal. The present invention relates to a dual clamshell mobile communication terminal provided with an antenna.

일반적으로, 이동통신 단말기는 단말기가 위치하고 있는 장소로부터 가까운 곳에 설치된 기지국과 알에프(RF : Radio Frequency)신호를 송/수신함으로써 특정 상대방과의 정보 전달 및 다양한 부가 서비스를 제공받고 있다.In general, a mobile communication terminal transmits / receives a base station and a radio frequency (RF) signal installed near a place where a terminal is located to receive information and to provide various additional services to a specific counterpart.

이와 같은 기지국과의 무선신호 송/수신은 이동통신 단말기에 구비되는 안테나를 통해 수행되는데, 상기 안테나는 단말기 본체에 연결되어 수신되는 무선주파신호를 단말기 본체 내부에 설치된 인쇄회로 기판으로 전달하고, 인쇄회로 기판을 통해 전달되는 무선주파신호를 외부로 발신한다.The radio signal transmission / reception with the base station is performed through an antenna provided in the mobile communication terminal. The antenna transmits the radio frequency signal received by being connected to the terminal body to a printed circuit board installed inside the terminal body, and printing. It transmits the radio frequency signal transmitted through the circuit board to the outside.

이러한 안테나는 수납형 안테나 및 고정형 안테나로 나뉘는 노출형 안테나와, 단말기의 본체 내에 내설되는 내장형으로 크게 나뉘어진다.Such antennas are broadly divided into an exposed antenna divided into a storage antenna and a fixed antenna, and a built-in type installed in the main body of the terminal.

도 6 및 도 7을 참조하여 종래의 폴더형 이동통신 단말기에 설치된 노출형 안테나의 구성을 설명하면 다음과 같다.Referring to Figures 6 and 7, the configuration of an exposed antenna installed in a conventional clamshell mobile communication terminal is as follows.

도 6 및 도 7에 도시된 노출형 안테나(101)는 폴더(110)와 힌지장치(130)로 결합된 본체(120)의 최상단에서 일정길이 돌출되게 설치되고, 본체(120)에 장착된 인쇄회로기판(140)의 알에프모듈(141)(RF Module)과 급전선(142)으로 연결되며, 상기 안테나(101)를 통하여 전파가 송수신되어 상대방과 무선으로 전화통화가 가능하게된다.The exposure type antenna 101 illustrated in FIGS. 6 and 7 is installed to protrude a predetermined length from the top of the main body 120 coupled with the folder 110 and the hinge device 130, and is mounted on the main body 120. The RF module 141 of the circuit board 140 is connected to a feed line 142, and radio waves are transmitted / received through the antenna 101 so that a telephone call can be made wirelessly with the other party.

그러나 상기와 같은 노출형 안테나는 이동통신 단말기의 외부에 노출되도록 장착되므로 사용중에 외부에 걸려서 부러지거나 파손되는 경우가 있으며, 단말기의 소형화에 따라 주머니 등에 단말기를 넣고 다니는 경우나, 상기 단말기를 급히 꺼내서 사용할 경우에 상기 안테나 부위가 주머니에 걸리는 등의 사용 및 휴대상의 불편한 점이 있다.However, since the exposed antenna is mounted to be exposed to the outside of the mobile communication terminal, it may be broken or damaged due to external use during use, and when the terminal is miniaturized, the terminal may be carried in a pocket or the like, or the terminal may be quickly taken out. When used, there is an inconvenience in use and portability such as the antenna portion is caught in the pocket.

이와같은 노출형 안테나의 단점을 해결하기 위하여 최근에는 내장형 안테나를 구비한 단말기가 점점 사용되는 추세인데, 상기와 같은 내장형 안테나는 이동통신 단말기내에서 많은 공간을 차지하여 인쇄회로기판과 기구물의 공간효용에 큰 제약을 준다는 문제점이 있다.Recently, in order to solve the disadvantage of the exposed antenna, a terminal having a built-in antenna has been increasingly used. The built-in antenna as described above occupies a lot of space in a mobile communication terminal, thereby making effective use of printed circuit boards and equipment. There is a problem that gives a big constraint.

또한, 상기와 같은 내장형 안테나는 인쇄회로기판에 설치된 각종회로에 의한 전파간섭을 받지않기 위하여 최소한 인쇄회로기판과 7mm이상의 간격을 유지시켜야 하므로 주로 단말기의 본체 상측부에 내설되며, 이것으로 인하여 단말기 본체의 상측부가 두꺼워져 단말기 본체의 슬림화에 역행되거나 휴대 및 제품의 디자인적 미감이 저하되는 단점이 있다.In addition, the built-in antenna as described above is mainly installed in the upper side of the main body of the terminal because it must maintain a distance of at least 7mm with the printed circuit board in order not to receive radio interference by various circuits installed on the printed circuit board. Due to the thickening of the upper side thereof, there is a disadvantage in that the slimness of the main body of the terminal or the design and aesthetics of the portable and product are deteriorated.

본 발명은 상술한 종래 기술의 문제점을 해결하기 위한 것으로서, 이동통신 단말기의 폴더 외측면에 근접하도록 안테나를 내장하므로써 이동통신 단말기를 슬림화하고 전자파에 의한 피해를 줄이는 내장형 안테나가 구비된 듀얼 폴더형 이동통신 단말기를 제공하는 것을 그 목적으로 한다.The present invention is to solve the above-mentioned problems of the prior art, a dual foldable mobile with a built-in antenna to reduce the damage caused by electromagnetic waves by slimming the mobile communication terminal by embedding the antenna close to the outer surface of the folder of the mobile communication terminal It is an object to provide a communication terminal.

또한, 상기 안테나는 도체면에 마이크로 스트립 선로가 형성된 마이크로 스트립형 안테나로 형성되는 것을 특징으로 한다.In addition, the antenna is characterized in that it is formed of a microstrip type antenna with a microstrip line formed on the conductor surface.

또한, 상기 안테나연결수단은 안테나에 일단이 연결되고 타단은 본체의 인쇄회로기판에 연결되는 연성인쇄회로기판으로 이루어지는 것을 특징으로 한다.In addition, the antenna connection means is characterized in that the one end is connected to the antenna and the other end is made of a flexible printed circuit board is connected to the printed circuit board of the main body.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 보다 구체적으로 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

Therefore, it is attached to the lower portion of the adhesive layer 20.

상기 안테나(30)는 다수의 직선선로(32)가 내부에 구비된 연성회로기판(FPCB : Flexible printed circuit board)으로 이루어져 알에프(RF : Radio Frequency)신호를 송수신하게 된다.The antenna 30 is made of a flexible printed circuit board (FPCB) having a plurality of straight lines 32 therein to transmit and receive RF signals.

안테나연결수단(40)은 연성회로기판(FPCB : Flexible printed circuit board)로 이루어져 상기 안테나(30) 가장자리의 소정위치에 그 일단이 연결되고, 타단은 힌지(8)의 내부를 통하여 본체(3)에 구비된 메인 인쇄회로기판(5)에 전기적으로 연결되며, 상기 양 끝단에는 컨넥터(42)가 구비되어 연결이 용이하게 될 수 있다.The antenna connection means 40 is made of a flexible printed circuit board (FPCB), one end of which is connected to a predetermined position of the edge of the antenna 30, the other end of the main body (3) through the interior of the hinge (8) It is electrically connected to the main printed circuit board 5 provided in the connector, both ends are provided with a connector 42 can be easily connected.
