Description

콤보 안테나 모듈Combo Antenna Module
본 발명은 전자기기에 실장되는 콤보 안테나 모듈에 관한 것으로, 더욱 상세하게는 서로 다른 주파수 대역에 공진하는 복수의 안테나를 포함하는 콤보 안테나 모듈에 관한 것이다.The present invention relates to a combo antenna module mounted on an electronic device, and more particularly, to a combo antenna module including a plurality of antennas resonating in different frequency bands.
기술의 발전과 함께 휴대폰, 피디에이(PDA), 피엠피(PMP), 내비게이션, 랩톱 등과 같은 휴대 단말들은 통화, 동영상/음악 재생, 길안내 등과 같은 기본 기능 이외에도 디엠비, 무선 인터넷, 기기 간의 근거리 통신 등의 기능을 추가로 제공하고 있다. 그에 따라, 휴대 단말은 무선 인터넷, 블루투스 등과 같이 무선통신을 위한 복수의 안테나를 구비한다.With the development of technology, mobile terminals such as mobile phones, PDAs, PMPs, navigation devices, and laptops have provided basic functions such as calls, video/music playback, and directions, as well as DMB, wireless Internet, and short-distance communication Additional functions are provided. Accordingly, the mobile terminal is provided with a plurality of antennas for wireless communication such as wireless Internet and Bluetooth.
이외에도, 최근에는 근거리 통신(즉, NFC)을 이용하여 단말 간의 정보 교환, 결제, 티켓 예매, 검색 등의 기능을 휴대 단말에 적용하는 추세에 있다. 이를 위해, 휴대 단말에는 근거리 통신 방식에 사용되는 안테나 모듈(즉, NFC 안테나 모듈)이 장착되고 있다. 이때, 사용되는 NFC 안테나 모듈은 전자태그(RFID)의 하나로 대략 13.56㎒ 정도의 주파수 대역을 사용하는 비접촉식 근거리 무선통신 모듈로 10cm 정도의 가까운 거리에서 단말 간 데이터를 전송한다. NFC는 결제뿐만 아니라 슈퍼마켓이나 일반 상점에서 물품 정보나 방문객을 위한 여행 정보 전송, 교통, 출입통제 잠금장치 등에 광범위하게 활용된다.In addition, in recent years, there is a trend to apply functions such as information exchange, payment, ticket reservation, and search between terminals using short-distance communication (ie, NFC) to mobile terminals. To this end, the portable terminal is equipped with an antenna module (ie, NFC antenna module) used for short-range communication. At this time, the NFC antenna module used is a contactless short-range wireless communication module using a frequency band of about 13.56 MHz as one of the RFID tags and transmits data between terminals at a short distance of about 10 cm. NFC is widely used not only for payment, but also for product information or travel information transmission for visitors in supermarkets and general stores, transportation, and access control locks.
또한, 최근에는 애플 페이, 삼성 페이 등과 같이 휴대 단말을 이용한 전자 결제에 관련된 기능이 요구됨에 따라 전자 결제용 안테나가 휴대 단말에 실장되고 있다. 일례로, 삼성 페이는 마그네틱 보안 전송 방식을 이용한 전자 결제를 수행하기 때문에, 삼성 페이를 지원하는 휴대 단말에서는 MST(Magnetic Secure Transmission) 안테나가 실장되고 있다.In addition, in recent years, as functions related to electronic payment using a mobile terminal such as Apple Pay and Samsung Pay are required, an antenna for electronic payment is being mounted on a mobile terminal. For example, since Samsung Pay performs electronic payment using a magnetic secure transmission method, a magnetic secure transmission (MST) antenna is mounted in a mobile terminal supporting Samsung Pay.
한편, 휴대 단말은 시장에서 소형화, 박형화가 요구됨에 따라 실장 공간이 점차 줄어들고 있는 추세에 있다. 이에, 휴대 단말 제조업체에서는 복수의 안테나를 하나로 통합한 콤보 안테나 모듈을 휴대 단말에 적용하고 있다.On the other hand, as the market demands for miniaturization and thinness of the portable terminal, the mounting space is gradually decreasing. Accordingly, a portable terminal manufacturer is applying a combo antenna module in which a plurality of antennas are integrated into a portable terminal.
이와 함께, 휴대 단말 제조업체는 휴대 단말 시장에서 단가 경쟁이 심해짐에 따라 여러 부품의 단가를 절감하기 위한 다양한 콤보 안테나 모듈을 개발하고 있다. 일례로, 콤보 안테나 모듈은 FPCB, 차폐 시트, 방열 시트 등과 같이 여러 복합 자재로 구성되고 있어, 자재의 사이즈 축소를 통해 휴대 단말의 단가를 절감하기 위한 다양한 연구가 진행되고 있다.At the same time, mobile terminal manufacturers are developing various combo antenna modules to reduce the cost of various parts as price competition intensifies in the mobile terminal market.

전자결제용 방사 패턴(214)은 제2 무선 전력 전송용 방사 패턴(212b)의 인접한 두 턴 사이에 배치된다. 이때, 제2 무선 전력 전송용 방사 패턴(212b)이 연성인쇄회로기판(211)을 사이에 두고 중첩되는 제1 무선 전력 전송용 방사 패턴(212a)과 동일한 선폭을 유지하면, 제2 무선 전력 전송용 방사 패턴(212b)과 전자결제용 방사 패턴(214) 사이의 이격 폭(거리) 확보를 위해 연성인쇄회로기판(211)의 사이즈가 증가할 수밖에 없다.The radiation pattern 214 for electronic payment is disposed between two adjacent turns of the radiation pattern 212b for the second wireless power transmission. At this time, when the second wireless power transmission radiation pattern 212b maintains the same line width as the first wireless power transmission radiation pattern 212a overlapping with the flexible printed circuit board 211 interposed therebetween, the second wireless power transmission In order to secure a separation width (distance) between the radiation pattern 212b for electronic payment and the radiation pattern 214 for electronic payment, the size of the flexible printed circuit board 211 is inevitably increased.
이에, 도 9를 참조하면, 제2 무선 전력 전송용 방사 패턴(212b)의 일부는 연성인쇄회로기판(211)을 사이에 두고 중첩되는 제1 무선 전력 전송용 방사 패턴(212a)보다 좁은 선폭을 갖는다. 제2 무선 전력 전송용 방사 패턴(212b)은 최외곽 턴에서 내부 방향으로 2~3개의 턴에서 제1 무선 전력 전송용 방사 패턴(212a)보다 좁은 선폭을 갖는다.Accordingly, referring to FIG. 9 , a portion of the second radiation pattern for wireless power transmission 212b has a narrower line width than the first radiation pattern 212a for wireless power transmission overlapping with the flexible printed circuit board 211 interposed therebetween. have The second radiation pattern for wireless power transmission 212b has a line width narrower than that of the first radiation pattern 212a for wireless power transmission in 2-3 turns in the inner direction from the outermost turn.
이때, 제2 무선 전력 전송용 방사 패턴(212b)의 선폭, 전자결제용 방사 패턴(214)의 선폭, 제2 무선 전력 전송용 방사 패턴(212b)과 전자결제용 방사 패턴(214)의 이격 폭을 합산한 값은 제1 무선 전력 전송용 방사 패턴(212a)의 선폭과 동일하다. 여기서, 선폭이 동일한 것은 정확히 동일한 것뿐만 아니라 오차범위 내의 차이를 갖는 경우도 포함할 수 있다.At this time, the line width of the radiation pattern 212b for the second wireless power transmission, the line width of the radiation pattern 214 for electronic payment, the separation width between the radiation pattern 212b for the second wireless power transmission and the radiation pattern 214 for electronic payment A value obtained by summing up is the same as the line width of the first radiation pattern 212a for wireless power transmission. Here, the same line width may include not only exactly the same thing but also a case of having a difference within an error range.
일례로, 제1 무선 전력 전송용 방사 패턴(212a)의 선폭이 대략 1mm인 것으로 가정하면, 최외곽 턴에서 2~32개의 턴에서 제2 무선 전력 전송용 방사 패턴(212b)의 선폭은 대략 0.7mm 정도이고, 전자결제용 방사 패턴(214)의 선폭은 대략 0.1mm 정도이고, 제2 무선 전력 전송용 방사 패턴(212b)과 전자결제용 방사 패턴(214)의 이격 폭은 대략 0.1mm 정도일 수 있다.As an example, assuming that the line width of the first radiation pattern for wireless power transmission 212a is approximately 1 mm, the line width of the second radiation pattern 212b for wireless power transmission in 2 to 32 turns in the outermost turn is approximately 0.7 mm, the line width of the radiation pattern 214 for electronic payment is about 0.1 mm, and the separation width between the second radiation pattern 212b for wireless power transmission and the radiation pattern 214 for electronic payment can be about 0.1 mm. have.
이처럼, 본 발명의 제2 실시 예에 따른 콤보 안테나 모듈(200)은 일면의 무선 전력 전송용 방사 패턴(212) 중 일부 턴(Turn)의 선폭을 줄이고, 선폭이 줄어든 무선 전력 전송용 방사 패턴(212) 사이의 이격 공간을 통해 전자 결제용 방사 패턴이 권회하도록 구성된다. 이에, 근거리 통신용 방사 패턴(213)의 상부 또는 하부에 전자결제용 방사 패턴(214)이 배치된 제1 실시 예의 콤보 안테나 모듈(100)에 비해 연성인쇄회로기판(211)의 사이즈를 줄일 수 있다.As such, the combo antenna module 200 according to the second embodiment of the present invention reduces the line width of some turns of the radiation pattern 212 for wireless power transmission on one side, and the radiation pattern for wireless power transmission with the reduced line width ( 212) through the space between the radiation pattern for electronic payment is configured to be wound. Accordingly, it is possible to reduce the size of the flexible printed circuit board 211 compared to the combo antenna module 100 of the first embodiment in which the radiation pattern 214 for electronic payment is disposed above or below the radiation pattern 213 for short-range communication. .
또한, 전자결제용 방사 패턴(214)은 무선전력 전송용 방사 패턴과 권취축을 공유하고, 무선전력 전송용 방사 패턴과 동일한 방향으로 권취축을 권회하고, 무선전력 전송용 방사 패턴의 일부와 같이 소정 턴(대략 2~3턴 정도) 권회한다.In addition, the radiation pattern for electronic payment 214 shares a winding axis with the radiation pattern for wireless power transmission, winds the winding shaft in the same direction as the radiation pattern for wireless power transmission, and turns a predetermined turn like a part of the radiation pattern for wireless power transmission (Approximately 2-3 turns)
이에, 본 발명의 제2 실시 예에 따른 콤보 안테나 모듈(200)은 근거리 통신용 방사 패턴(213)의 인식 범위, 인식 거리 등을 그대로 유지하면서 전자결제용 방사 패턴(214)이 형성되는 영역(즉, 근거리 통신용 방사 패턴(213)의 상부 및 하부)을 줄일 수 있어 연성인쇄회로기판(211)의 사이즈를 제1 실시 예의 연성인쇄회로기판(111)의 사이즈보다 줄일 수 있다.Accordingly, the combo antenna module 200 according to the second embodiment of the present invention maintains the recognition range and recognition distance of the radiation pattern 213 for short-range communication as it is, while maintaining the area in which the radiation pattern 214 for electronic payment is formed (that is, , the upper and lower portions of the radiation pattern 213 for short-range communication) can be reduced, so that the size of the flexible printed circuit board 211 can be reduced compared to the size of the flexible printed circuit board 111 of the first embodiment.
또한, 본 발명의 제2 실시 예에 따른 콤보 안테나 모듈(200)은 연성인쇄회로기판(211)의 사이즈를 줄임으로써, 콤보 안테나 모듈(200)의 단가를 줄일 수 있다.In addition, the combo antenna module 200 according to the second embodiment of the present invention reduces the size of the flexible printed circuit board 211 , thereby reducing the unit cost of the combo antenna module 200 .
또한, 본 발명의 제2 실시 예에 따른 콤보 안테나 모듈(200)은 무선 전력 전송용 방사 패턴(212) 중 일부 턴(Turn)의 선폭을 줄이고, 선폭이 줄어든 무선 전력 전송용 방사 패턴(212) 사이의 이격 공간을 통해 전자 결제용 방사 패턴이 권회함으로써, 전자결제용 방사 패턴(214)에 의한 주변 간섭이 줄어 근거리 통신용 방사 패턴(213)의 인식 거리 및 인식 영역을 증가시킬 수 있다.In addition, the combo antenna module 200 according to the second embodiment of the present invention reduces the line width of some turns among the radiation patterns 212 for wireless power transmission, and the radiation pattern 212 for wireless power transmission with a reduced line width. As the radiation pattern for electronic payment is wound through the spaced apart space therebetween, ambient interference caused by the radiation pattern for electronic payment 214 is reduced and the recognition distance and recognition area of the radiation pattern 213 for short-distance communication can be increased.
또한, 본 발명의 제2 실시 예에 따른 콤보 안테나 모듈(200)은 연성인쇄회로기판(211)의 사이즈가 감소함에 따라 방사 패턴이 작아져서 자기 필드를 집중시켜 스몰 태그(Small Tag)와의 통신 성능을 향상시킬 수 있다.In addition, in the combo antenna module 200 according to the second embodiment of the present invention, as the size of the flexible printed circuit board 211 decreases, the radiation pattern becomes smaller and the magnetic field is concentrated to perform communication with a small tag. can improve
이를 통해, 제1 실시 예의 콤보 안테나 모듈(100)이 대략 107mmХ60mm 정도의 사이즈를 갖는 연성인쇄회로기판(211)으로 구성된 경우, 제2 실시 예의 콤보 안테나 모듈(200)은 대략 63mmХ49mm 정도의 사이즈로 제1 실시 예의 콤보 안테나 모듈(100)과 동등 이상의 안테나 성능을 구현할 수 있다.Through this, when the combo antenna module 100 of the first embodiment is composed of a flexible printed circuit board 211 having a size of about 107mmХ60mm, the combo antenna module 200 of the second embodiment is about 63mmХ49mm in size. Antenna performance equal to or higher than that of the combo antenna module 100 of the first embodiment may be implemented.
다만, 본 발명의 제2 실시 예에 따른 콤보 안테나 모듈(200)은 전자결제용 방사 패턴(214)이 연성인쇄회로기판(211)의 중심부에 집중되기 때문에 전자결제용 방사 패턴(214)의 인식 범위가 줄어들 수 있다.However, the combo antenna module 200 according to the second embodiment of the present invention recognizes the radiation pattern 214 for electronic payment because the radiation pattern 214 for electronic payment is concentrated in the center of the flexible printed circuit board 211 . range may be reduced.
도 10 내지 도 12를 참조하면, 본 발명의 제2 실시 예에 따른 콤보 안테나 모듈(200)은 제2 면에 배치된 전자결제용 방사 패턴(214)의 일부(대략 3/4 턴 정도)가 무선 전력 전송용 방사 패턴(212)을 따라 권회하고, 나머지(대략 1/4 턴 정도)가 무선 전력 전송용 방사 패턴(212) 및 근거리 통신용 방사 패턴(213)을 관통하여 도면상 근거리 통신용 방사 패턴(213)의 하부를 권회할 수도 있다. 즉, 전자결제용 방사 패턴(214)은 무선 전력 전송용 방사 패턴(212)의 이격 공간, 무선 전력 전송용 방사 패턴(212)의 외주와 근거리 통신용 방사 패턴(213)의 내주 사이의 공간, 근거리 통신용 방사 패턴(213)의 외주에 배치된 공간을 따라 권회한다.10 to 12, in the combo antenna module 200 according to the second embodiment of the present invention, a part (about 3/4 turn) of the radiation pattern 214 for electronic payment disposed on the second surface It is wound along the radiation pattern 212 for wireless power transmission, and the remainder (about 1/4 turn) penetrates the radiation pattern 212 for wireless power transmission and the radiation pattern 213 for short-range communication, and the radiation pattern for short-distance communication in the drawing The lower part of (213) may be wound. That is, the radiation pattern 214 for electronic payment is a space between the spaced apart space of the radiation pattern 212 for wireless power transmission, the outer periphery of the radiation pattern 212 for wireless power transmission and the inner periphery of the radiation pattern 213 for short-distance communication, a short-range It is wound along the space arranged on the outer periphery of the radiation pattern 213 for communication.
이를 위해, 제2 무선 전력 전송용 방사 패턴(212b)과 근거리 통신용 방사 패턴(213)에는 전자결제용 방사 패턴(214)이 관통하는 관통 경로가 형성된다. 여기서, 관통 경로는 방사 패턴이 연성인쇄회로기판(211)의 제1 면으로 우회함에 따라 방사 패턴이 형성되지 않은 공간인 것을 일례로 한다.To this end, a penetration path through which the radiation pattern 214 for electronic payment passes is formed in the second radiation pattern 212b for wireless power transmission and the radiation pattern 213 for short-range communication. Here, it is assumed that the through path is a space in which the radiation pattern is not formed as the radiation pattern detours to the first surface of the flexible printed circuit board 211 .
무선 전력 전송용 방사 패턴(212)은 제1 관통 경로(212c) 및 제2 관통 경로(212d)가 형성되고, 근거리 통신용 방사 패턴(213)은 제3 관통 경로(213a) 및 제4 관통 경로(213b)가 형성된 것을 일례로 한다.The radiation pattern 212 for wireless power transmission includes a first through-path 212c and a second through-path 212d, and the radiation pattern 213 for short-range communication includes a third through-path 213a and a fourth through-path ( 213b) is formed as an example.
이때, 전자결제용 방사 패턴(214)은 제1 관통 경로(212c) 및 제3 관통 경로(213a)를 순차적으로 관통하여 도면상 근거리 통신용 방사 패턴(213)의 하부로 진출하고, 제4 관통 경로(213b) 및 제3 관통 경로(213a)를 순차적으로 관통하여 무선 전력 전송용 방사 패턴(212)으로 진입한다. At this time, the radiation pattern for electronic payment 214 passes through the first through-path 212c and the third through-path 213a sequentially to advance to the lower portion of the radiation pattern 213 for short-range communication in the drawing, and the fourth through-path Sequentially passes through 213b and the third through-path 213a to enter the radiation pattern 212 for wireless power transmission.
물론, 전자결제용 방사 패턴(214)은 제2 관통 경로(212d) 및 제4 관통 경로(213b)를 순차적으로 관통하여 도면상 근거리 통신용 방사 패턴(213)의 하부로 진출하고, 제3 관통 경로(213a) 및 제1 관통 경로(212c)를 순차적으로 관통하여 무선 전력 전송용 방사 패턴(212)으로 진입할 수도 있다.Of course, the radiation pattern 214 for electronic payment passes through the second through-path 212d and the fourth through-path 213b sequentially to advance to the lower portion of the radiation pattern 213 for short-range communication in the drawing, and the third through-path The radiation pattern 212 for wireless power transmission may be sequentially passed through the 213a and the first through-path 212c.
이처럼, 본 발명의 제2 실시 예에 따른 콤보 안테나 모듈(200)은 전자결제용 방사 패턴(214)이 무선 전력 전송용 방사 패턴(212)의 이격 공간과 도면상 근거리 통신용 방사 패턴(213)의 외부에 걸쳐 루프를 형성함으로써, 전자결제용 방사 패턴(214)의 인식 범위를 제1 실시 예의 콤보 안테나 모듈(100)과 동등한 수준으로 유지하면서 연성인쇄회로기판(211)의 사이즈를 최소화할 수 있다.As such, in the combo antenna module 200 according to the second embodiment of the present invention, the radiation pattern 214 for electronic payment is a space between the radiation pattern 212 for wireless power transmission and the radiation pattern 213 for short-range communication in the drawing. By forming a loop over the outside, the size of the flexible printed circuit board 211 can be minimized while maintaining the recognition range of the radiation pattern 214 for electronic payment at the same level as that of the combo antenna module 100 of the first embodiment. .
이상에서 본 발명에 따른 바람직한 실시 예에 대해 설명하였으나, 다양한 형태로 변형이 가능하며, 본 기술분야에서 통상의 지식을 가진 자라면 본 발명의 특허청구범위를 벗어남이 없이 다양한 변형 예 및 수정 예를 실시할 수 있을 것으로 이해된다.Although the preferred embodiment according to the present invention has been described above, it can be modified in various forms, and those of ordinary skill in the art can make various modifications and modifications without departing from the scope of the claims of the present invention.
