본 발명은 이동통신 단말기에 관한 것이다.The present invention relates to a mobile communication terminal.

이동통신 단말기의 수요가 급속도로 증가하면서, 다양한 서비스와 여러 가지 편리한 기능을 제공하는 이동통신 단말기가 제공되고 있다.As the demand for mobile communication terminals increases rapidly, mobile communication terminals providing various services and various convenient functions have been provided.

최근에는 음성·영상 등 다양한 멀티미디어 신호를 디지털 방식으로 변조, 고정 또는 휴대용과 차량용 수신기에 제공하는 방송서비스인 디지털 멀티미디어 방송(Digital Multimedia Broadcasting, DMB)이 제공되고 있어 이와 관한 이동통신 단말기의 보급이 증가하고 있다.Recently, Digital Multimedia Broadcasting (DMB), a broadcasting service that digitally modulates, fixes, or provides portable and vehicle receivers various multimedia signals such as voice and video, has been provided. Doing.

이러한 디지털 멀티미디어 방송은 디지털 라디오용 기술인 DAB(Digital Audio Broadcasting)에 바탕을 두고 있으며, 여기에 멀티미디어 방송 개념이 추가되어 동영상과 날씨·뉴스·위치 등 데이터 정보를 추가로 보낼 수 있는 서비스이다.The digital multimedia broadcasting is based on digital audio broadcasting (DAB), a technology for digital radio, and the concept of multimedia broadcasting is added to the service to send data information such as video, weather, news, and location.

따라서, 이동중에도 개인휴대단말기나 차량용 단말기를 통해 CD·DVD급의 고음질·고화질 방송을 즐길 수 있어 차세대 방송으로 주목받고 있으며, 전송망에 따라 위성파와 지상파로 구분된다.As a result, CD-DVD-class high-quality and high-definition broadcasts can be enjoyed through personal mobile terminals or vehicle terminals while being on the move, and are attracting attention as next-generation broadcasts.

여기서, 지상파 디지털 멀티미디어 방송은 지상에서 주파수를 이용하여 프로그램을 전송하는데, 이때, 저주파를 이용하기 때문에 이동통신 단말기에는 저주파를 용이하게 송수신할 수 있는 안테나가 장착되어야 한다.Here, terrestrial digital multimedia broadcasting transmits a program using a frequency on the ground. In this case, since a low frequency is used, the mobile communication terminal should be equipped with an antenna capable of easily transmitting and receiving low frequencies.

그러나, 저주파용 안테나는 기존 공중파 방송과 거의 같은 저주파 대역(200MHz대)을 쓰기 때문에 길이가 긴 안테나를 사용해야 한다.However, since the low frequency antenna uses a low frequency band (200 MHz band) which is almost the same as that of a conventional over-the-air broadcasting, a long antenna must be used.

그러나, 이동통신 단말기의 특성상 안테나의 길이가 길면 휴대성 면에서 매우 불편하고, 물리적으로 안테나 크기를 대폭 줄이면, 그만큼 수신율이 떨어지고 상대적으로 특성 열화가 발생하는 문제점이 있었다.However, due to the characteristics of the mobile communication terminal, the long antenna length is very inconvenient in terms of portability, and when the antenna size is physically reduced, the reception rate decreases and the characteristic degradation occurs relatively.

이러한 종래기술의 문제점을 해결하기 위한 본 발명의 목적은, 폴더부의 개폐시 안테나의 길이가 가변되도록 하는 이동통신 단말기를 제공하는 데에 그 목적이 있다.An object of the present invention for solving the problems of the prior art is to provide a mobile communication terminal that the length of the antenna is variable when opening and closing the folder portion.

이와 같은 목적을 달성하기 위한 본 발명의 이동통신 단말기는, 제1 안테나부를 구비한 본체부; 본체부와 연결되어 개폐되고, 제2 안테나부를 구비한 폴더부; 및 제1 안테나부와 제2 안테나부를 연결하며, 폴더부의 개폐시 제1 안테나부와 제2 안테나부의 길이를 가변시키는 연결부를 포함하는 것을 특징으로 한다.A mobile communication terminal of the present invention for achieving the above object, the main body having a first antenna; A folder part connected to the main body part to be opened and closed and having a second antenna part; And a connecting part connecting the first antenna part and the second antenna part to vary the length of the first antenna part and the second antenna part when the folder part is opened and closed.

여기서, 제1 안테나부와 제2 안테나부는, 본체부와 폴더부의 일측에 대향하여 형성되는 것을 특징으로 한다.Here, the first antenna portion and the second antenna portion, characterized in that formed on the opposite side of the main body portion and the folder portion.

이러한, 연결부는 폴더부가 폐쇄되면 제1 안테나부와 제2 안테나부의 일측이 포개지도록 하고, 폴더부가 개방되면 제1 안테나부와 제2 안테나부를 길게 연장시키는 것을 특징으로 한다.When the folder part is closed, the connection part overlaps one side of the first antenna part and the second antenna part, and when the folder part is opened, the first antenna part and the second antenna part are elongated.

이때, 연결부는 연성 회로기판(Flexible Printed Circuit) 또는 연성 동축 케이블(Flexible Coaxial Cable) 중 어느 하나로 형성되는 것을 특징으로 한다.In this case, the connection part may be formed of any one of a flexible printed circuit and a flexible coaxial cable.

이하, 본 발명의 바람직한 실시예에 따른 이동통신 단말기를 도면을 참조하여 상세하게 설명한다.Hereinafter, a mobile communication terminal according to a preferred embodiment of the present invention will be described in detail with reference to the drawings.

도 1은 본 발명의 일 실시예에 따른 이동통신 단말기를 나타낸 측면도이고, 도 2는 본 발명의 일 실시예에 따른 이동통신 단말기를 나타낸 평면도이다.1 is a side view showing a mobile communication terminal according to an embodiment of the present invention, Figure 2 is a plan view showing a mobile communication terminal according to an embodiment of the present invention.

먼저, 본체부(100)는 이동통신 단말기의 몸체로써, 전면부에는 키입력부(105)를, 후면부에는 배터리(미도시) 등을 구비한다.First, the main body 100 is a body of a mobile communication terminal, and includes a key input unit 105 in the front part and a battery (not shown) in the rear part.

폴더부(110)는 소정의 데이터를 표시하는 표시부(115)를 구비하고, 본체부(100)와 결합하여 개폐시 이동통신 단말기의 전체 길이를 가변시킨다.The folder unit 110 includes a display unit 115 for displaying predetermined data, and is coupled to the main body unit 100 to change the overall length of the mobile communication terminal when opening and closing.

이러한, 본체부(100)와 폴더부(110)는 그 일측에 각각 제1 안테나부(120)와 제2 안테나부(125)를 구비한다.The main body unit 100 and the folder unit 110 include a first antenna unit 120 and a second antenna unit 125 on one side thereof.

여기서, 제1 안테나부(120)와 제2 안테나부(125)는 전기적인 신호를 전파로 바꾸어 주거나 그 반대의 기능을 수행한다. 즉, 송신의 경우에는 송신기에서 보내고 싶은 전기적인 신호를 전파로 바꾸어 전송하고, 전파를 수신하면 그 전파를 전기적인 신호로 바꾸어 수신기에 전달한다.Here, the first antenna unit 120 and the second antenna unit 125 converts an electric signal into radio waves or vice versa. That is, in the case of transmission, the electric signal desired to be sent by the transmitter is converted into an electric wave, and when the electric wave is received, the electric signal is converted into an electric signal and transmitted to the receiver.

이러한, 제1 안테나부(120)와 제2 안테나부(125)는 소정의 연결부(130)로 연결되는 데 이를 좀 더 상세히 살펴보면 도 3과 같다.The first antenna unit 120 and the second antenna unit 125 are connected to a predetermined connection unit 130, which will be described in detail with reference to FIG. 3.

도 3은 이동통신 단말기의 안테나 부분을 나타낸 부분 확대도이다.3 is a partially enlarged view illustrating an antenna portion of a mobile communication terminal.

도 3에 도시된 바와 같이, 이동통신 단말기의 안테나 부분은 제1 안테나부(120), 제2 안테나부(125) 및 연결부(130)를 포함하여 이루어진다.As shown in FIG. 3, the antenna portion of the mobile communication terminal includes a first antenna unit 120, a second antenna unit 125, and a connection unit 130.

제1 안테나부(120)는 본체부(100)의 일측에 마련되고, 제2 안테나부(125)는 폴더부(110)의 일측에 마련되며, 소정의 연결부(130)를 통하여 서로 연결된다.The first antenna unit 120 is provided at one side of the main body unit 100, the second antenna unit 125 is provided at one side of the folder unit 110, and is connected to each other through a predetermined connection unit 130.

이러한 연결부(130)는 연성 동축 케이블(Flexible Coaxial Cable)로 형성된다. 연성 동축 케이블(Flexible Coaxial Cable)이란, 긴 원통 모양의 외부도체와 그 중심축에 놓인 1개의 내부도체로 이루어진 전송선로로써 선로의 단면을 보면 외부도체와 내부도체가 동심원을 이룬 동축 케이블을 유연성이 있도록 형성된 것을 말한다.The connection part 130 is formed of a flexible coaxial cable. Flexible coaxial cable is a transmission line consisting of a long cylindrical outer conductor and one inner conductor placed on its central axis.As a cross-section of a line, a flexible coaxial cable is flexible. Refers to what is formed.

이러한, 동축 케이블은 직류를 포함한 저주파에서 수십 메가 헤르쯔(MHz)의 고주파까지의 전기신호를 전송할 수 있으며, 동일 케이블 속에 복수의 동축케이블을 수용해도 상호간의 신호누설이 적은 이점이 있다.Such a coaxial cable can transmit an electric signal from a low frequency including a direct current to a high frequency of several tens of megahertz (MHz), and even if a plurality of coaxial cables are accommodated in the same cable, signal leakage between each other is small.

이러한 연성 동축 케이블로 형성된 연결부(130)를 이용하여 제1 안테나부(120)와 제2 안테나부(125)를 연결한다.The first antenna unit 120 and the second antenna unit 125 are connected by using the connection unit 130 formed of the flexible coaxial cable.

이때, 연결부(130)는 폴더부(110)가 폐쇄되는 경우에, 제1 안테나부(120)와 제2 안테나부(125)의 일측이 포개지도록 하고, 폴더부(110)가 개방되는 경우에는, 제1 안테나부(120)와 제2 안테나부(125)를 길게 연장시킨다.At this time, when the folder unit 110 is closed, the connection unit 130 is to be superposed one side of the first antenna unit 120 and the second antenna unit 125, and when the folder unit 110 is opened The length of the first antenna unit 120 and the second antenna unit 125 is extended.

이와 같이, 폴더부(110)가 폐쇄되는 경우에 제1 안테나부(120)와 제2 안테나부(125)의 일측이 포개지도록 하므로써, 이동통신 단말기의 크기를 증가시키거나 외부로 돌출된 긴 길이의 안테나를 사용하지 않고도 수신율을 향상시킬 수 있다.As such, when the folder unit 110 is closed, one side of the first antenna unit 120 and the second antenna unit 125 are overlapped, thereby increasing the size of the mobile communication terminal or prolonging the length of the mobile communication terminal. The reception rate can be improved without using an antenna.

이와 함께, 폴더부(110)가 개방되는 경우에 제1 안테나부(120)와 제2 안테나부(125)를 길게 연장시키므로써 수직 접지 안테나(Monopole Antenna)로 사용하는 것이 가능하도록 한다.In addition, when the folder unit 110 is opened, the first antenna unit 120 and the second antenna unit 125 may be extended to be used as a vertical ground antenna.

즉, 안테나가 직선 형태로 형성되며, 안테나 한쪽을 이동통신 단말기에 접지로 대치하므로써, 짧은 λ(파장)/4의 길이로 안테나의 기능을 한다.That is, the antenna is formed in a straight line, and by replacing one antenna with ground to the mobile communication terminal, the antenna functions as a short λ / 4 wavelength.

여기서는, 연결부(130)가 연성 동축 케이블로 형성된 것에 대해서만 설명하였지만, 이에 한정되는 것은 아니고, 연성 회로기판(Flexible Printed Circuit)으로 형성되는 것이 가능하다.Herein, only the connection part 130 is formed of a flexible coaxial cable, but the present invention is not limited thereto. The connection part 130 may be formed of a flexible printed circuit.

또한, 위에서는 제1 안테나부(120)가 본체부(100)의 일측에 마련되고, 제2 안테나부(125)가 폴더부(110)의 일측에 마련되는 것에 대해서만 설명하였지만, 이에 한정되는 것은 아니다.In addition, in the above description, only the first antenna unit 120 is provided on one side of the main body unit 100 and the second antenna unit 125 is provided on one side of the folder unit 110, but the present invention is not limited thereto. no.

즉, 제1 안테나부(120)와 제2 안테나부(125)는 서로 대향하여 각각 본체부(100)와 폴더부(110)의 어느 부분에도 형성하는 것이 가능한데, 이는 안테나의 위치가 안테나의 송수신 성능에 영향을 미치지 않는 범위안에서 결정되는 것이 바람직하다.That is, the first antenna unit 120 and the second antenna unit 125 may be formed at any part of the main body unit 100 and the folder unit 110 to face each other. It is desirable to determine within a range that does not affect performance.

또한, 위에서는 제1 안테나부(120)와 제2 안테나부(125)가 폴더형 이동통신 단말기에 형성된 것에 대해서만 설명하였지만, 이에 한정되는 것은 아니다.In addition, although the first antenna unit 120 and the second antenna unit 125 have been described above only in the folding type mobile communication terminal, the present invention is not limited thereto.

즉, 슬립형 또는 휴대폰과 PDA 기능을 합친 단말기에 무선랜과 휴대폰 기능을 동시에 탑재한 스윙폰 및 슬립 스윙폰 등과 같이 이동통신 단말기의 전체 길이가 가변되며 개폐되는 모든 이동통신 단말기에 적용되는 것이 가능하다.That is, the total length of the mobile communication terminal is variable and can be applied to all mobile communication terminals that are open and closed, such as a swing phone and a slip swing phone equipped with a wireless LAN and a mobile phone function in a terminal of a sleep type or a mobile phone and a PDA function. .

이와 같이, 본체부(100) 및 폴더부(110)에 각각 제1 안테나부(120)와 제2 안테나부(125)를 구비하고, 이를 소정의 연결부(130)를 이용하여 연결하므로써, 폴더부(110)의 개폐시 그 길이를 가변시킬 수 있다.As such, the main body 100 and the folder unit 110 are provided with the first antenna unit 120 and the second antenna unit 125, respectively, and by connecting them using a predetermined connection unit 130, the folder unit It is possible to vary the length of the opening and closing 110.

이상에서 설명한 바와 같이 본 발명에 따르면, 폴더부의 개폐시 안테나의 길이가 가변되도록 하므로써 물리적으로 안테나 크기를 줄이지 않고도 수신율을 향상시키는 효과가 있다.As described above, according to the present invention, the length of the antenna is variable when the folder is opened and closed, thereby improving the reception rate without physically reducing the size of the antenna.

또한, 특성 열화를 방지하는 효과가 있다.In addition, there is an effect of preventing the deterioration of characteristics.
