본 발명은 수신감도를 개선한 이동 통신 단말기에 관한 것으로서, 보다 상세하게는 수신감도가 다른 안테나를 선택적으로 사용하여 수신감도를 개선함으로써, 이동 통신 단말기의 파워 출력을 최소화하여 전자파를 최소화하고 배터리 사용시간을 증가시키는 기술이다.The present invention relates to a mobile communication terminal having improved reception sensitivity, and more particularly, to improve reception sensitivity by selectively using antennas having different reception sensitivity, thereby minimizing power output of the mobile communication terminal to minimize electromagnetic waves and using batteries. It is a technique that increases time.

일반적으로 이동 통신 단말기는 팜PC, PDA(personal Digital Assistants; 개인용 디지털 보조기), 휴대전화, 및 HPC(Hand-held PC: 휴대용 PC) 등을 총칭하는 것으로서, 장소에 구애받지 않고 무선통신은 물론 네트워크 접속을 통한 각종 업무를 수행할 수 있는 첨단 통신기기를 말한다.In general, mobile terminals are palm PCs, personal digital assistants (PDAs), mobile phones, and handheld PCs (HPCs). It is a high-tech communication device that can perform various tasks through connection.

이러한 이동 통신 단말기는 통상 360도의 방사패턴을 갖는 안테나를 구비하고, 기지국과의 계속적인 통신을 통해 상대측 단말기와 통화를 하게 된다.Such a mobile communication terminal is generally provided with an antenna having a radiation pattern of 360 degrees, and makes a call with the other terminal through continuous communication with the base station.

이때, 이동통신 단말기는 기지국의 근방에 위치하여 서비스를 제공받는 경우 기지국으로부터 수신된 그 신호의 세기가 강해져 수신감도가 좋고, 이동 통신 단말기가 기지국으로부터 멀리 떨어져 있으면서 서비스를 제공받고 있다면 수신된 신호의 세기가 약해져 수신감도가 떨어진다.At this time, when the mobile communication terminal is located in the vicinity of the base station and receives the service, the strength of the signal received from the base station is increased, so that the reception sensitivity is good, and if the mobile communication terminal is receiving the service while being far from the base station, The strength is weakened and the reception sensitivity is lowered.

특히, 수신감도가 안 좋아지면 이동 통신 단말기는 파워 출력을 높여 수신감도를 높이게 되는데, 파워 출력이 높아질수록 유해 전자파의 방출이 많아지게 되고 배터리 사용시간이 감소하게 되는 문제점이 있다. 따라서, 파워 출력을 높이지 않고 수신감도를 개선하는 방법이 필요하다.In particular, when the reception sensitivity is not good, the mobile communication terminal increases the power output to increase the reception sensitivity. As the power output increases, the emission of harmful electromagnetic waves increases and the battery usage time decreases. Therefore, there is a need for a method of improving reception sensitivity without increasing power output.

상기와 같은 문제점을 해결하기 위한 본 발명의 목적은, 육방면체의 다중 안테나를 구비함으로써 안테나를 선택적으로 사용하여 수신 감도를 개선시키는데 있다.An object of the present invention for solving the above problems is to improve the reception sensitivity by selectively using an antenna by having a multi-antenna of hexagonal.

또한, 본 발명의 다른 목적은, 복수개의 안테나의 수신세기를 각각 체크하여 수신세기가 가장 좋은 안테나를 사용하도록 함으로써, 단말기의 출력을 최소화하여 유해한 전자파의 출력을 감소시키고 배터리 사용시간을 증가시키는데 있다.In addition, another object of the present invention is to check the reception strength of a plurality of antennas to use the antenna with the best reception strength, thereby minimizing the output of the terminal to reduce the output of harmful electromagnetic waves and increase the battery usage time. .

상기 과제를 달성하기 위한 본 발명에 따른 수신감도를 개선한 이동 통신 단말기는, 복수개의 안테나를 포함하는 다중 안테나와, 복수개의 안테나로부터 수신 한 각각의 수신신호의 세기를 체크하여 그 결과에 따라 제어신호를 출력하는 모바일 스테이션 모뎀과, 제어신호에 의해 제어되어 상기 복수개의 안테나 중 하나를 선택하는 선택부를 포함하여 구성함을 특징으로 한다.According to an aspect of the present invention, a mobile communication terminal having improved reception sensitivity checks the strength of a multi-antenna including a plurality of antennas and the strength of each received signal received from the plurality of antennas and controls the result accordingly. And a selector for selecting one of the plurality of antennas controlled by a control signal and a mobile station modem for outputting a signal.

또한, 본 발명에 따른 이동 통신 단말기는, 무선 통신을 위한 이동 통신 단말기에 있어서, 각 면에 대하여 최대이득마진을 갖는 복수개의 안테나를 구비하는 육방면체의 다중 안테나를 포함하여 구성함을 특징으로 한다.In addition, the mobile communication terminal according to the present invention is characterized in that the mobile communication terminal for wireless communication, comprising a multiplex of a hexagonal cube having a plurality of antennas having a maximum gain margin for each surface. .

이하, 첨부된 도면을 참조하여 본 발명의 실시예를 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 실시예에 따른 이동 통신 단말기의 개략적인 구성도이다.1 is a schematic configuration diagram of a mobile communication terminal according to an embodiment of the present invention.

도 1에 따른 이동 통신 단말기는, 다중안테나(100), 선택부(200), 듀플렉서(300), 및 모바일 스테이션 모뎀(400)을 구비한다.The mobile communication terminal according to FIG. 1 includes a multiple antenna 100, a selector 200, a duplexer 300, and a mobile station modem 400.

다중안테나(100)는 육방면체 다중 안테나로서 육방면체의 각 면에 대해 최고의 이득마진을 갖는 6개의 안테나를 구비한다. 이때, 6개의 안테나는 듀플렉서(300)에 접속되는 피딩포인트(feeding poing)를 각각 구비한다. 이와같이, 육방면체의 안테나는 360도의 방사패턴이 아닌 60도의 방사패턴을 형성하므로 그 수신율이 개선된다. The multi-antenna 100 is a hexagonal multiple antenna and has six antennas having the best gain margins for each side of the hexagonal body. At this time, the six antennas are each provided with a feeding point (feeding poing) connected to the duplexer (300). In this way, since the antenna of the hexagonal body forms a radiation pattern of 60 degrees instead of the radiation pattern of 360 degrees, its reception rate is improved.

선택부(200)는 6개의 안테나 중 하나를 선택적으로 듀플렉서(300)에 연결시킨다. 이때, 선택부(200)는 모바일 스테이션 모뎀(400)으로부터 출력되는 제어신호 SW_CTR에 의해 제어되는 스위칭소자로 구현되는 것이 바람직하다.The selector 200 selectively connects one of the six antennas to the duplexer 300. In this case, the selector 200 may be implemented as a switching device controlled by the control signal SW_CTR output from the mobile station modem 400.

듀플렉서(300)는 송신신호와 수신신호를 구분하여, 선택부(200)로부터 수신 한 수신신호를 모바일 스테이션 모뎀(400)으로 출력하고, 모바일 스테이션 모뎀(400)으로부터 수신한 송신신호를 선택부(200)에 인가한다. The duplexer 300 classifies the transmission signal and the reception signal, outputs the reception signal received from the selection unit 200 to the mobile station modem 400, and outputs the transmission signal received from the mobile station modem 400 to the selection unit ( 200).

모바일 스테이션 모뎀(400)은 6개의 안테나를 통해 수신된 신호를 각각 수신받아 각 신호들의 세기를 체크하여, 신호의 세기가 가장 큰 안테나를 사용하도록 선택부(200)를 제어하는 제어신호 SW_CTR를 출력한다. The mobile station modem 400 receives signals received through six antennas, checks the strength of each signal, and outputs a control signal SW_CTR for controlling the selector 200 to use the antenna having the largest signal strength. do.

이와같이, 본 발명의 이동 통신 단말기가 기지국에 대해 어떤 방향으로 사용되더라도 6개의 안테나 중 가장 수신감도가 좋은 안테나를 사용하도록 함으로써 파워 출력을 최소화할 수 있다.As such, even if the mobile communication terminal of the present invention is used in any direction with respect to the base station, power output can be minimized by using the antenna having the best reception sensitivity among the six antennas.

이하, 도 1의 이동 통신 단말기의 수신감도 개선 방법을 구체적으로 설명하기로 한다.Hereinafter, a method of improving reception sensitivity of the mobile communication terminal of FIG. 1 will be described in detail.

먼저, 모바일 스테이션 모뎀(400)은 다중안테나(100)의 6개의 안테나가 각각 수신한 신호의 세기를 체크하여 그 결과에 따른 제어신호 SW_CTR를 선택부(200)에 인가한다. 이때, 모바일 스테이션 모뎀(400)은 이동 통신 단말기가 통화중이거나 아이들상태인 경우 주기적으로 다중안테나(100)의 수신세기를 체크하도록 하는 것이 바람직하다.First, the mobile station modem 400 checks the strength of signals received by six antennas of the multi-antenna 100 and applies the control signal SW_CTR to the selector 200 according to the result. In this case, the mobile station modem 400 preferably checks the reception strength of the multi-antenna 100 periodically when the mobile communication terminal is busy or idle.

그 후, 선택부(200)는 신호의 세기가 가장 큰 안테나로부터 수신한 수신신호를 듀플렉서(300)에 인가하고, 듀플렉서(300)는 그 수신신호를 모바일 스테이션 모뎀(400)에 인가한다. 그에 따라, 모바일 스테이션 모뎀(400)은 파워출력을 낮게 유지할 수 있다.Thereafter, the selector 200 applies the received signal received from the antenna having the largest signal strength to the duplexer 300, and the duplexer 300 applies the received signal to the mobile station modem 400. As such, the mobile station modem 400 can keep the power output low.

이와같이, 본 발명은 육방면체의 다중 안테나를 사용하여 수신감도를 개선하 고, 다중 안테나의 각각의 수신세기를 체크하여 수신세기가 좋은 안테나를 사용하도록 하여, 수신감도를 좋게 유지함으로써 파워출력을 낮게 유지하도록 한다.As described above, the present invention improves the reception sensitivity by using the multi-antenna of the hexagonal cube, and checks the reception strength of each of the multiple antennas so that an antenna having good reception strength is used, and thus the power reception is kept low by maintaining the reception sensitivity. Keep it.

이상에서 살펴본 바와 같이, 본 발명은 육방면체의 다중 안테나를 구비함으로써 안테나의 수신 감도를 개선하는 효과가 있다.As described above, the present invention has the effect of improving the reception sensitivity of the antenna by having a multiple antenna of a hexagon.
