It is preferable to comprise a part.

이하에서는 첨부한 도면을 참조하여 본 발명의 바람직한 실시예에 따른 이동 통신 단말기의 듀얼 안테나 장치에 대해서 상세하게 설명한다.Hereinafter, a dual antenna device of a mobile communication terminal according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 일 실시예에 따른 이동 통신 단말기의 듀얼 안테나 장치의 구성을 보인 도로, 제어부(10)와, FM 수신기(30)와, FM 송신기(20)와, 제1스위칭부(40)와, 안테나 매칭 회로부(50)와, 내장형 안테나(60)와, 제2스위칭부(70)와, 이어잭부(80)를 구비하여 이루어진다.1 is a road showing a configuration of a dual antenna device of a mobile communication terminal according to an embodiment of the present invention, the controller 10, the FM receiver 30, the FM transmitter 20, the first switching unit 40 ), An antenna matching circuit unit 50, an internal antenna 60, a second switching unit 70, and an ear jack unit 80.

이와 같은 구성에 있어서, 제어부(10)는 이동 통신 단말기의 전반적인 동작을 제어하되, FM 송신시에는 안테나단이 FM 송신기(20)에 연결(핀 2와 핀 3 연결) 되도록 제1스위칭부(40)를 제어하고, FM 수신시에는 안테나단이 FM 수신부에 연결(핀 1과 핀 3 연결)되도록 제1스위칭부(40)를 제어한다.In such a configuration, the control unit 10 controls the overall operation of the mobile communication terminal, the first switching unit 40 so that the antenna terminal is connected to the FM transmitter 20 (pin 2 and pin 3 connection) during FM transmission. ), And controls the first switching unit 40 so that the antenna terminal is connected to the FM receiver (pin 1 and pin 3 connected) during the FM reception.

제1스위칭부(40)는 제어부(10)의 제어하에 FM 수신기(30) 또는 FM 송신기(20)를 안테나단에 연결시킴으로써, FM 송신기(20)와 FM 수신기(30) 사이에 상호 간섭이 일어나지 않도록 한다.The first switching unit 40 connects the FM receiver 30 or the FM transmitter 20 to the antenna terminal under the control of the controller 10, so that mutual interference does not occur between the FM transmitter 20 and the FM receiver 30. Do not

안테나 매칭 회로부(50)는 매칭 소자(L, C)로 구현되어 FM 송/수신부(20/30)와 내장형 안테나(60) 사이의 임피던스 매칭을 수행한다.The antenna matching circuit unit 50 is implemented with matching elements L and C to perform impedance matching between the FM transmitter / receiver 20/30 and the internal antenna 60.

내장형 안테나(60)는 이동 통신 단말기 내부 적소에 내장되어, 안테나 매칭 회로부(50)로부터 전달받은 FM 주파수를 송출하거나, 라디오 방송국에서 송출하는 FM 주파수 신호를 수신하여 안테나 매칭 회로부(50)로 전달한다.The built-in antenna 60 is embedded in the mobile communication terminal in place, and transmits the FM frequency received from the antenna matching circuit unit 50, or receives and transmits an FM frequency signal transmitted from a radio station to the antenna matching circuit unit 50. .

제2스위칭부(70)는 평상시에는 이어잭부(80)와 비연결 상태(핀 1과 핀 3 연결)를 유지하여 이어잭부(80)로부터 인가되는 간섭 노이즈를 차단하고, 이어잭부(80)로부터 인에이블 신호를 인가받으면 이어잭부(80)를 안테나 매칭 회로부(50)에 연결한다.The second switching unit 70 maintains the non-connection state (pin 1 and pin 3 connection) with the ear jack 80 at normal times to block the interference noise applied from the ear jack 80, and from the ear jack 80 Upon receiving the enable signal, the ear jack 80 is connected to the antenna matching circuit 50.

이어잭부(80)는 이어폰(90) 삽입에 따라 인에이블 신호를 발생시켜 제2스위칭부(70)로 인가한다.The ear jack 80 generates an enable signal according to the insertion of the earphone 90 and applies it to the second switching unit 70.

이하에서는 1을 참조하여 본 발명에 따른 이동 통신 단말기의 듀얼 안테나 장치의 동작에 대해서 설명한다.Hereinafter, with reference to 1 will be described the operation of the dual antenna device of the mobile communication terminal according to the present invention.

우선, 이어폰(90)이 이어잭부(80)에 삽입되지 않은 경우에는 제2스위칭부(70)가 이어잭부(80)와 비연결 상태로 유지되므로, 이동 통신 단말기는 내장형 안 테나(60)를 통해 FM 신호를 송수신한다.First, when the earphone 90 is not inserted into the ear jack portion 80, since the second switching portion 70 is maintained in a non-connected state with the ear jack portion 80, the mobile communication terminal is a built-in antenna (60) Send and receive FM signals.

반면에, 이어폰(90)이 이어잭부(80)에 삽입되게 되면, 이어잭부(80)가 제2스위칭부(70)로 인에이블 신호를 인가하게 되며, 이어잭부(80)로부터 인에이블 신호를 인가받은 제2스위칭부(70)는 이어잭부(80)를 안테나 매칭 회로부(50)에 연결시켜 내장형 안테나(60)와 함께 이어폰(90)을 이득 상승용 보조 안테나로 사용한다.On the other hand, when the earphone 90 is inserted into the ear jack 80, the ear jack 80 applies the enable signal to the second switching unit 70, the enable signal from the ear jack 80 The licensed second switching unit 70 connects the ear jack unit 80 to the antenna matching circuit unit 50 to use the earphone 90 together with the built-in antenna 60 as a gain raising auxiliary antenna.

전술한 바와 같이, 이어잭부(80)에 이어폰(90)이 삽입됨에 따라, 제2스위칭부(70)가 이어잭부(80)를 안테나 매칭 회로부(50)에 연결시키게 되면, 이어잭부(80)를 통해 간섭 노이즈가 인가되는 데, 이어잭부(80)에서 발생하는 간섭 노이즈는 내장형 안테나(60)와 함께 이어폰(90)을 안테나로 사용하여 얻어지는 안테나 이득에 비해 미세하므로 문제가 되지 않는다.As described above, when the earphone 90 is inserted into the ear jack 80, when the second switching unit 70 connects the ear jack 80 to the antenna matching circuit 50, the ear jack 80 is provided. Interference noise is applied through, but the interference noise generated from the ear jack portion 80 is not a problem because it is fine compared to the antenna gain obtained by using the earphone 90 as an antenna with the built-in antenna 60.

본 발명의 이동 통신 단말기의 듀얼 안테나 장치는 전술한 실시예에 국한되지 않고 본 발명의 기술 사상이 허용하는 범위 내에서 다양하게 변형하여 실시할 수 있다.The dual antenna device of the mobile communication terminal of the present invention is not limited to the above-described embodiment, and may be variously modified and implemented within the range permitted by the technical idea of the present invention.

이상에서 설명한 바와 같은 본 발명의 이동 통신 단말기의 듀얼 안테나 장치에 따르면, 이어잭에 이어폰이 미삽입된 경우에는 FM용 내장형 안테나를 사용하고, 이어폰이 삽입된 경우에는 이어폰을 이득 상승용 보조 안테나로 사용함으로써, 안테나 이득을 상승시킬 수 있게 된다.According to the dual antenna device of the mobile communication terminal of the present invention as described above, when the earphone is not inserted into the ear jack, the built-in antenna for FM is used, and when the earphone is inserted, the earphone is used as an auxiliary antenna for gain rise. By using this, the antenna gain can be increased.
