Description

안테나 구조체Antenna structure
본 발명은 안테나 구조체에 관한 것으로서, 보다 상세하게는 NFC 패턴, MST 패턴 및 WPC 패턴이 하나의 기판에 동시에 형성된 복합 안테나 구조체에 관한 것이다.The present invention relates to an antenna structure, and more particularly, to a composite antenna structure in which an NFC pattern, an MST pattern, and a WPC pattern are simultaneously formed on one substrate.
이동통신 단말기, 보다 구체적으로 스마트폰이 널리 보급됨에 따라 최근의 스마트폰에는 사용자에게 편의를 제공할 수 있는 다양한 기능들이 탑재되고 있으며, 그 중 대표적인 것으로써 손쉬운 결제를 위한 NFC(Near Frequency Communication) 및 MST(Magnetic secure Transmission)기능과 이동통신 단말기 유선 충전의 한계를 극복한 무선충전(WPC, Wireless Power Charge)기능 들 수 있다. As mobile communication terminals, more specifically, smart phones are widely used, various smart phones have recently been equipped with various functions to provide convenience to the user. Among them, NFC (Near Frequency Communication) for easy payment and MST (Magnetic Secure Transmission) function and Wireless Power Charge (WPC) function that overcomes the limitations of mobile terminal wired charging.
NFC 및 MST 기능이 이동통신 단말기에 탑재됨으로써 사용자들은 더 이상 결제를 위해 지갑에서 신용카드를 꺼낼 필요가 없어졌으며, 무선충전 기능이 탑재됨으로써 이동통신 단말기를 충전하는 동안에도 케이블에 구애받지 않고 자유롭게 단말기의 사용이 가능해졌다. 이러한 기능들은 모두 이동통신 단말기에 실장되는 안테나에 의해 가능한 것들이다. With the NFC and MST features on mobile terminals, users no longer need to remove their credit cards from their wallets for payments, and the wireless charging feature allows users to freely rely on cables while charging their mobile terminals. Can be used. These functions are all possible by the antenna mounted in the mobile communication terminal.
한편, 점점 얇아지고 작아지는 최근의 이동통신 단말기의 경향에 따라 안테나를 실장할 수 있는 공간 역시 작아질 수밖에 없으며, 하나의 기판에 복수의 안테나를 실장하는 연구가 계속되고 있다. 하나의 기판에 복수의 안테나를 동시에 실장하는 경우 공간을 효율적으로 활용할 수 있는 배치의 문제에서부터 안테나 상호 간의 간섭을 최소화해야 하는 문제까지 해결해야 할 과제가 상당히 많다. 아울러, 세 개 이상의 안테나를 하나의 기판에 동시에 실장해야 하는 경우 두 개의 안테나는 필수적으로 동일한 면에 형성할 수밖에 없으므로 이러한 문제는 더욱 심화될 수밖에 없다. On the other hand, according to the recent trend of thinner and smaller mobile communication terminal, the space for mounting an antenna is also inevitably smaller, and researches for mounting a plurality of antennas on one substrate are continuing. When multiple antennas are mounted on a single board at the same time, there are a lot of problems to be solved, such as the problem of layout that can effectively use space, and the problem of minimizing interference between antennas. In addition, when three or more antennas must be simultaneously mounted on one substrate, the two antennas are inevitably formed on the same surface.
따라서 본 발명을 통해 사용자의 편의를 위한 NFC 및 MST 기능과 무선충전 기능을 제공할 수 있는 NFC 안테나, MST 안테나 및 WPC 안테나를 효율적인 공간 활용을 통해 하나의 기판에 동시에 형성함과 동시에 최적의 성능을 도출할 수 있는 새롭고 진보적인 안테나 구조체를 제안하고자 한다. Therefore, the present invention simultaneously forms an NFC antenna, an MST antenna, and a WPC antenna, which can provide NFC and MST functions and a wireless charging function for the convenience of the user, on the same substrate through efficient space utilization, and at the same time, achieve optimal performance. We propose a new and advanced antenna structure that can be derived.

The embodiments to be described are provided so that those skilled in the art can easily understand the technical spirit of the present invention, and thus, the present invention is not limited thereto. In this case, detailed description thereof will be omitted.
또한, 첨부된 도면에 표현된 사항들은 본 발명의 실시 예들을 쉽게 설명하기 위해 도식화된 도면으로 실제로 구현되는 형태와 상이할 수 있으며, 각 도면의 구성요소들에 참조부호를 부가함에 있어서, 동일한 구성요소들에 대해서는 비록 다른 도면상에 표시되더라도 가능한 한 동일한 부호를 가지도록 하고 있음에 유의해야 한다.In addition, the matters represented in the accompanying drawings may be different from the form actually embodied in the schematic drawings in order to easily explain the embodiments of the present invention. In addition, in addition to the reference numerals to the components of the drawings, the same configuration It is to be noted that the elements are designated by the same reference numerals as much as possible even if they are shown in different drawings.
또한, 어떤 구성요소들을 '포함'한다는 표현은, '개방형의 표현'으로서 해당 구성요소들이 존재하는 것을 단순히 지칭하는 표현이며, 추가적인 구성요소들을 배제하는 것으로 이해되어서는 안 될 것이다.In addition, the expression "comprising" certain elements is merely an expression of an 'open', and simply refers to the existence of the elements, and should not be understood as excluding additional elements.
한편, 이하의 명세서에서 언급할 NFC 패턴, MST 패턴, WPC 패턴은 각각 13.56 MHz, 100KHz, 125KHz를 가용 주파수로 하는 NFC 안테나, MST 안테나, WPC 안테나로 넓게 볼 수 있을 것이다.Meanwhile, NFC patterns, MST patterns, and WPC patterns to be mentioned in the following specification will be widely seen as NFC antennas, MST antennas, and WPC antennas having 13.56 MHz, 100 KHz, and 125 KHz as available frequencies, respectively.
도 1은 본 발명의 일 실시 예에 따른 안테나 구조체(100)의 단면을 나타내는 도면이다. 1 is a view showing a cross section of the antenna structure 100 according to an embodiment of the present invention.
안테나 구조체(100)는 기판(10) 및 쉴딩시트(20)를 포함할 수 있으며, 쉴딩시트(20)는 나노 크리스탈층(25)를 포함할 수 있다. 그러나 이는 하나의 실시 예일 뿐이며, 필요에 따라 일부 구성이 추가되거나 삭제될 수 있음은 물론이다. The antenna structure 100 may include a substrate 10 and a shielding sheet 20, and the shielding sheet 20 may include a nano crystal layer 25. However, this is only one embodiment, and of course, some configurations may be added or deleted as necessary.
기판(10)은 소정 형상을 나타낼 수 있으며, 여기서 소정 형상은 안테나 구조체(100)가 실장되는 이동통신 단말기의 위치에 따라 상이해질 수 있다. 예를 들어, 안테나 구조체(100)가 배터리 위에 실장된다면 기판(10)은 배터리 단면의 형상과 동일하거나 유사한 형상을 나타낼 수 있으며, 글래스 뒤에 실장된다면 글래스 단면의 형상과 동일하거나 유사한 형상을 나타낼 수 있다. The substrate 10 may have a predetermined shape, and the predetermined shape may be different according to the position of the mobile communication terminal in which the antenna structure 100 is mounted. For example, if the antenna structure 100 is mounted on a battery, the substrate 10 may have a shape that is the same as or similar to that of the battery cross-section, and if the antenna structure 100 is mounted behind the glass, the substrate 10 may have the same or similar shape to the shape of the glass cross-section. .
이러한 기판(10)에는 후술할 안테나 패턴들이 형성되어야 하므로 일반적인 인쇄회로기판(PCB, Printed Circuit Board)을 이용할 수 있으며, 유연성을 가져 최근 다방면으로 활용되고 있는 연성회로기판(FPCB, Flexible Printed Circuit Board)을 이용할 수도 있다. FPCB를 이용하는 경우 PCB에 비해 더 얇기 때문에 공간 활용적인 측면에서 보다 바람직하다. Since the antenna patterns to be described later should be formed on the substrate 10, a general printed circuit board (PCB) may be used, and flexible printed circuit boards (FPCBs), which are recently used in various fields with flexibility, may be used. Can also be used. In the case of using FPCB, since it is thinner than PCB, it is more preferable in terms of space utilization.
한편, 기판(10)의 하면에는 완충제가 형성되어 안테나 구조체(100)가 실장되는 이동통신 단말기의 배터리 또는 글래스와 접촉하여 발생하는 스크러치를 방지할 수 있다. 여기서 완충제는 공지의 구성을 이용할 수 있으며, 예를 들어, 스폰지, 종이 중 어느 하나를 이용할 수 있으며, 명칭에 구애받지 않고 접촉하여 발생하는 스크러치를 방지할 수 있는 어떤 것이라도 완충제로 이용 가능하다. On the other hand, a buffer is formed on the lower surface of the substrate 10 to prevent scratches caused by contact with the battery or glass of the mobile communication terminal in which the antenna structure 100 is mounted. Here, the buffer may use a known configuration, for example, any one of a sponge or paper, and any one that can prevent scratches caused by contact irrespective of the name can be used as the buffer. .
쉴딩시트(20)는 기판(10)의 상면에 접착제를 통해 적층되며, 쉴딩시트(20)는 나노 크리스탈층(25)을 포함할 수 있다. 여기서 나노 크리스탈층(25)은 종래의 NFC 및 WPC 안테나 복합체에 있어서 페라이트(Ferrite)시트 및 아몰포스(Amorphous) 시트를 대체할 수 있는 구성인바, 복수의 시트를 하나의 층으로 구성함으로써 안테나 구조체(100) 전체 두께가 얇아지는 효과를 얻을 수 있다. The shielding sheet 20 may be stacked on the upper surface of the substrate 10 through an adhesive, and the shielding sheet 20 may include a nano crystal layer 25. Here, the nano crystal layer 25 is a component that can replace a ferrite sheet and an amorphous sheet in a conventional NFC and WPC antenna composite, the antenna structure (by forming a plurality of sheets in one layer) 100) The overall thickness can be reduced.
한편, 나노 크리스탈층(25)의 상면에는 커버필름이 적층되어 나노 크리스탈층(25)의 표면을 보호하는 역할을 수행한다. On the other hand, the cover film is laminated on the upper surface of the nano crystal layer 25 serves to protect the surface of the nano crystal layer 25.
나노 크리스탈층(25)에 대하여 보다 상세히 설명하면, 나노 크리스탈층(25)은 제1 내지 제N(여기서 N은 양의 정수) 나노 리본이 접착제를 통해 적층된 구조를 나타낼 수 있다. 도 2는 5개의 나노 리본이 접착제를 통해 적층된 모습을 나타낸 도면인바, 나노 리본은 약 20μm의 두께를 갖고, 접착제는 약 5μm의 두께를 가져 전체 나노 크리스탈층(25)은 약 120μm의 두께를 갖는 것을 확인할 수 있다. 한편, 최상층의 나노 리본에는 상기 설명한 커버필름이 적층되어 나노 크리스탈층(25)의 표면을 보호할 수 있다, 커버필름은 약 15μm의 두께를 갖는다. In more detail with respect to the nano crystal layer 25, the nano crystal layer 25 may have a structure in which the first to N-th (where N is a positive integer) nano ribbon is laminated through an adhesive. FIG. 2 is a view illustrating five nano ribbons stacked through an adhesive, wherein the nano ribbons have a thickness of about 20 μm, the adhesives have a thickness of about 5 μm, and the entire nanocrystal layer 25 has a thickness of about 120 μm. I can confirm that I have. On the other hand, the above-described cover film is laminated on the uppermost nano ribbon can protect the surface of the nano-crystal layer 25, the cover film has a thickness of about 15μm.
한편, 나노 크리스탈층(25)은 Fe 93.4%, Si 4.86%, Cu 1.74%의 조성 함량을 나타내도록 제작하는 것이 바람직하나, 필요에 따라 일부 성분을 더 포함할 수 있으며, 조성 함량을 조절할 수 있음은 물론이다. On the other hand, the nano crystal layer 25 is preferably manufactured to exhibit a composition content of Fe 93.4%, Si 4.86%, Cu 1.74%, but may further include some components as necessary, the composition content can be adjusted Of course.
도 3은 본 발명의 일 실시 예에 따른 안테나 구조체(100)에 어트랙터(30)가 더 추가된 단면을 나타내는 도면이다.3 is a view showing a cross-section further added to the attractor 30 to the antenna structure 100 according to an embodiment of the present invention.
어트랙터(30)는 자성체가 포화되어 자기장이 바깥으로 퍼지고 그에 따라 발생하는 통신 효율의 저감(일종의 통신장애)을 방지하기 위한 구성으로써, 자기 흐름을 원활하게 하기 위해 고 포화 자화 값을 갖는 금속 성분으로 형성해야 하는바, 아몰포스(Amorphous) 성분을 함유하는 금속으로 형성함이 바람직하다. The attractor 30 is a component for preventing a decrease in communication efficiency (a kind of communication disturbance) caused by the saturation of a magnetic body and spreading of the magnetic field, and a metal component having a high saturation magnetization value for smoothing magnetic flow. It should be formed as, it is preferable to form with a metal containing an amorphous (Amorphous) component.
한편, 어트랙터(30)는 기판(10)과 쉴딩시트(20) 사이에 접착제를 통해 적층되며, 그 자체의 두께를 가지고 있기 때문에 기판(10) 상면에 적층되는 경우 두께가 증가하게 되는 문제가 발생할 수 있다. 이 경우 어트랙터(30)를 후술할 안테나 패턴들이 형성되지 않은 부분에 적층함으로써 두께 증가의 문제를 해결할 수 있다. 또한, 어트랙터(30)는 안테나 패턴들이 형성되지 않은 부분에 적층되므로 기판(10) 전체를 덮는 넓이로 형성하지 않아도 무방하며, 이 경우 지나치게 높은 포화 자화 값으로 인해 오히려 안테나 복합체(100) 성능에 악영향을 미칠 수 있다. 따라서 일 부분에만 형성하는 것이 바람직하다. 도 4를 참조하면 어트랙터의 구체적인 적층 위치를 확인할 수 있다. On the other hand, the attractor 30 is laminated between the substrate 10 and the shielding sheet 20 through an adhesive, and because it has its own thickness, when the stacked on the upper surface of the substrate 10 has a problem that the thickness increases May occur. In this case, it is possible to solve the problem of thickness increase by stacking the attractor 30 on a portion where the antenna patterns to be described later are not formed. In addition, since the attractor 30 may be stacked on a portion where the antenna patterns are not formed, the attractor 30 may not be formed to cover the entire substrate 10. In this case, due to the excessively high saturation magnetization value, the attractor 30 may have a negative effect on the performance of the antenna composite 100. May adversely affect Therefore, it is preferable to form only one part. Referring to FIG. 4, a specific stacking position of the attractor may be confirmed.
도 5는 본 발명의 일 실시 예에 따른 안테나 구조체(100)가 포함하는 기판(10)의 상면에 안테나 패턴들이 형성된 모습을 나타낸 도면이며, 도 6은 하면에 형성된 안테나 패턴들을 나타낸 도면이다. 안테나 패턴들은 도 5 및 6에 도시된 바와 같이 형성되는 것이 바람직하지만, 이는 본 발명의 일 실시 예에 따른 안테나 구조체(100)가 최적의 성능을 도출할 수 있도록 하는 하나의 실시 예일 뿐이며, 필요에 따라 안테나 패턴들의 형상 및 배치가 달라질 수 있음은 물론이다. FIG. 5 is a view illustrating antenna patterns formed on an upper surface of a substrate 10 included in an antenna structure 100 according to an embodiment of the present invention, and FIG. 6 illustrates antenna patterns formed on a lower surface thereof. Antenna patterns are preferably formed as shown in Figures 5 and 6, but this is only one embodiment that allows the antenna structure 100 according to an embodiment of the present invention to derive optimal performance, As a result, the shape and arrangement of the antenna patterns may vary.
기판(10)의 상면 또는 하면에는 NFC 패턴(12), MST 패턴(14) 및 WPC 패턴(17) 중 하나 이상이 형성되며, 결제와 무선충전 기능을 모두 수행하기 위해서는 NFC 패턴(12), MST 패턴(14) 및 WPC 패턴(17) 모두를 동시에 형성하는 것이 바람직하다. 구체적으로, NFC 패턴(12), MST 패턴(14) 및 WPC 패턴(17)은 소정 간격 이격하여 기판(10) 외곽으로부터 안쪽으로 순서대로 형성되는바, 이하, 도 7 내지 12를 참조하여 설명하도록 한다. One or more of the NFC pattern 12, the MST pattern 14, and the WPC pattern 17 are formed on the upper or lower surface of the substrate 10. In order to perform both payment and wireless charging functions, the NFC pattern 12, MST It is preferable to simultaneously form both the pattern 14 and the WPC pattern 17. In detail, the NFC pattern 12, the MST pattern 14, and the WPC pattern 17 are formed in order from the outside of the substrate 10 to be spaced apart from each other at a predetermined interval, and will be described below with reference to FIGS. 7 to 12. do.
도 7은 기판(10) 상면에 형성된 NFC 패턴(12)을 나타내는 도면이며, 도 8은 하면에 형성된 NFC 패턴(12)을 나타내는 도면이다.7 is a view showing the NFC pattern 12 formed on the upper surface of the substrate 10, Figure 8 is a view showing the NFC pattern 12 formed on the lower surface.
도 7을 참조하면, NFC 패턴(12)이 기판(10)의 6시 방향에 횡방향 및 그로부터 일단이 일부 절곡된 형상으로, 9시 방향에 종방향으로 그리고 중앙에 원형으로 형성된 것을 확인할 수 있으며, 도 8을 참조하면, NFC 패턴(12)이 기판(10)의 12시 방향에 횡방향으로, 6시 방향에 횡방향 및 그로부터 일단이 일부 절곡된 형상으로, 9시 방향과 3시 방향에 종방향으로 그리고 중앙에 원형으로 형성된 것을 확인할 수 있다. 이 경우, 기판(10) 상면의 3시 방향에는 종방향으로 NFC 패턴(12)이, 기판(10) 하면의 중앙 원형과 연결하는 NFC 패턴(12)이 형성되지 않지만 기판(10) 하면의 3시 방향에 종방향으로, 기판(10) 상면의 중앙 원형과 연결하는 NFC 패턴(12)이 형성되므로 기능상의 문제는 발생하지 않으며 오히려 3시 방향 및 중앙의 두께를 얇게할 수 있다. 여기서, 중앙에 원형으로 형성된 NFC 패턴(12)은 후술할 WPC 패턴(17)의 안쪽으로 이격되어 연장 형성되는바, 이를 통해 NFC의 성능을 획기적으로 개선할 수 있다. Referring to FIG. 7, it can be seen that the NFC pattern 12 is formed in a shape in which a transverse direction and one end thereof are partially bent from the 6 o'clock direction of the substrate 10, and a circular shape in the center and a center at the 9 o'clock direction. , Referring to FIG. 8, the NFC pattern 12 has a shape in which the substrate 10 is transverse to the 12 o'clock direction, the cross direction at the 6 o'clock direction, and one end thereof is partially bent, and at the 9 o'clock and 3 o'clock directions. It can be seen that it is formed circularly in the longitudinal direction and in the center. In this case, the NFC pattern 12 in the longitudinal direction is not formed in the 3 o'clock direction of the upper surface of the substrate 10, but the NFC pattern 12 is not formed in the longitudinal direction of the lower surface of the substrate 10. In the longitudinal direction in the longitudinal direction, the NFC pattern 12 is formed to connect with the central circle of the upper surface of the substrate 10 is not a functional problem occurs, rather it can be thinner at the 3 o'clock direction and the center thickness. Here, the NFC pattern 12 formed in the center is formed to be extended to be spaced apart inward of the WPC pattern 17 to be described later, through which can significantly improve the performance of NFC.
한편, 도 7 내지 8에는 NFC 패턴이 한 턴(Turn)의 도전선(라인)으로 도시되어 있으나, 이는 이해의 편의를 돕기 위한 예시적인 것일 뿐이며, 복수의 도전선으로 형성할 수 있음은 물론이다. 예를 들어, 12시 방향과 6시 방향에 횡방향으로 두 턴의 도전선을, 9시 방향과 3시 방향에 종방향으로 두 턴의 도전선을 형성할 수 있다. 이는 NFC 패턴(12)의 길이값을 확보하기 위한 것으로써 몇 턴으로 형성하든 전체 길이값을 확보할 수 있다면 무방하다. Meanwhile, although the NFC pattern is illustrated as a conductive line (line) of one turn in FIGS. 7 to 8, this is only an example for convenience of understanding and may be formed of a plurality of conductive lines. . For example, two turns of conductive lines may be formed in the transverse direction at 12 o'clock and 6 o'clock, and two turns of the conductive line in the longitudinal direction at the 9 o'clock and 3 o'clock directions. This is to secure the length value of the NFC pattern 12, and it may be as long as the total length value can be secured regardless of how many turns it is formed.
도 9는 기판(10) 상면에 형성된 MST 패턴(14)을 나타내는 도면이며, 도 10은 하면에 형성된 MST 패턴(14)을 나타내는 도면이다. 9 is a view showing the MST pattern 14 formed on the upper surface of the substrate 10, Figure 10 is a view showing the MST pattern 14 formed on the lower surface.
MST 패턴(14)은 기판(10) 상면 및 하면에 형성된 NFC 패턴(12)과 안쪽으로 접촉하지 않고 이격하여 형성되며, MST 패턴(14) 역시 길이값을 확보할 수 있을 정도의 턴 수로 형성하면 무방하다.The MST pattern 14 is formed to be spaced apart from the inner surface of the substrate 10 on the top and bottom of the NFC pattern 12 without contacting the inside, and the MST pattern 14 is also formed to have a number of turns enough to secure a length value. It's okay.
MST 패턴(14)의 경우 횡방향과 종방향의 길이에 특이점이 있는바, 횡방향의 길이가 후술할 WPC 패턴(17)의 지름 이하이며, 종방향의 길이가 WPC 패턴(17)의 지름 이상이다. 이는 도 11을 참조하면 구체적으로 확인할 수 있는바, MST 패턴(14)의 횡방향의 길이가 WPC 패턴(17)의 지름 이하이기 때문에 종방향의 MST 패턴(14)의 일부에 굴곡부(15)가 형성되어 있다. 이는 MST 패턴(14)의 종방향에 굴곡부(15)가 형성되지 않는다면 WPC 패턴(17)과 겹치기 때문에 이를 방지하기 위함이며, 굴곡부(15)가 형성되어 있기 때문에 그 만큼의 길이값을 더 확보할 수 있다. 또한, 정해진 기판(10) 사이즈의 제약 하에 효율적으로 안테나를 배치하여 공간을 활용할 수 있는 방법이기도 하다. In the case of the MST pattern 14, there is a singularity in the length of the transverse direction and the longitudinal direction. The length of the transverse direction is less than or equal to the diameter of the WPC pattern 17 to be described later, and the length of the longitudinal direction is greater than or equal to the diameter of the WPC pattern 17. to be. This can be confirmed in detail with reference to FIG. 11. Since the length in the lateral direction of the MST pattern 14 is less than or equal to the diameter of the WPC pattern 17, the bent portion 15 is formed in a part of the longitudinal MST pattern 14. Formed. This is to prevent the overlapping with the WPC pattern 17 if the bent portion 15 is not formed in the longitudinal direction of the MST pattern 14, and since the bent portion 15 is formed, it is possible to further secure the length value. Can be. In addition, it is also a method that can utilize the space by efficiently placing the antenna under the constraint of the predetermined substrate 10 size.
또한, MST 패턴(14)의 종방향의 길이는 WPC 패턴(17)의 지름 이상이므로 횡방향의 MST 패턴(14)의 일부에 굴곡부(15)가 형성될 필요가 없으나, 이는 하나의 실시 예일 뿐이며, MST 패턴(14)의 종방향의 길이 역시 WPC 패턴(17)의 지름 이하가 될 수도 있고 이 경우 횡방향의 MST 패턴(14)의 일부에 굴곡부(15)가 형성될 수 있다. 즉, MST 패턴(14)의 횡방향의 길이든 종방향의 길이든 어떤 것이나 WPC 패턴(17)의 지름 이상 또는 이하가 될 수 있으며, 이하가 되는 경우 MST 패턴(14)의 일부에 굴곡부(15)를 형성하여 WPC 패턴(17)과의 겹침을 방지하고 길이값을 확보할 수 있는 것이다. 예를 들어, 기판(10)의 사이즈가 작은 경우 WPC 패턴(17)과의 겹침을 방지하고 MST 패턴(14)의 길이 값을 확보하기 위해서는 횡방향 및 종방향 모두에 굴곡부(15)를 형성해야 할 것이다. In addition, since the length of the longitudinal direction of the MST pattern 14 is greater than or equal to the diameter of the WPC pattern 17, it is not necessary to form the bent portion 15 in a part of the transverse MST pattern 14, but this is only one embodiment. The length of the longitudinal direction of the MST pattern 14 may also be less than or equal to the diameter of the WPC pattern 17. In this case, the bent portion 15 may be formed in a part of the transverse MST pattern 14. That is, either the transverse length or the longitudinal length of the MST pattern 14 may be greater than or equal to or less than the diameter of the WPC pattern 17, and if it is less than or equal to the bent portion 15 of the MST pattern 14. ) To prevent overlapping with the WPC pattern 17 and to secure the length value. For example, when the size of the substrate 10 is small, in order to prevent overlap with the WPC pattern 17 and to secure the length value of the MST pattern 14, the bent portion 15 must be formed in both the transverse direction and the longitudinal direction. something to do.
한편, MST 패턴(14)은 최근 급속도로 보급되고 있는 신용카드 대체 결제를 위한 것이기 때문에 이동통신 단말기를 통해 결제를 하는 경우 POS 장치에 이동통신 단말기를 접근시키는 방향이 사용자마다 상이할 수 있다. 예를 들어, 어떤 사용자는 이동통신 단말기를 수평방향으로 하여 POS 단말기에 접근시킬 수 있을 것이며, 또 다른 사용자는 이동통신 단말기의 상단 또는 하단을 기울여 POS 단말기에 접근시킬 수 있을 것이다. 즉, 특정방향으로 이동통신 단말기를 접근시켜야만 결제가 수행된다면 사용자는 불편함을 느낄 수밖에 없을 것인바, 이를 해결하기 위한 수단이 필요하다. 이하 설명하도록 한다.On the other hand, since the MST pattern 14 is for the replacement of credit cards that are rapidly spreading recently, the direction of approaching the mobile communication terminal to the POS device may be different for each user when making a payment through the mobile communication terminal. For example, a user may access the POS terminal with the mobile terminal in a horizontal direction, and another user may access the POS terminal by tilting the top or bottom of the mobile terminal. That is, if payment is to be performed only when the mobile terminal is approached in a specific direction, the user will have no choice but to feel inconvenience. It will be described below.
기판(10)은 일측에 소정 형상의 연장부(11)를 포함할 수 있다. 연장부(11)는 앞서 언급했던 도면들에서 기판(10)의 12시 방향에 홀을 포함하는 부분을 나타내나, 반드시 홀을 포함할 필요는 없다. 이러한 연장부(11)에는 MST 패턴(14)이 연장 형성될 수 있는바, 이를 통해 사용자가 이동통신 단말기의 상단 또는 하단을 기울여 POS 단말기에 접근시킨다 하더라도 모든 방향을 커버하여 결제가 수행될 수 있다. 예를 들어, 연장부(11)가 이동통신 단말기의 상단쪽에 배치되는 경우 사용자가 이동통신 단말기의 상단을 기울여 POS 단말기에 접근시킨다면 연장부(11)에 형성된 MST 패턴(14)에 의해 결제가 수행될 것이며, 연장부(11)가 이동통신 단말기의 하단쪽에 배치되는 경우 사용자가 이동통신 단말기의 하단을 기울여 POS 단말기에 접근시킨다면 연장부(11)에 형성된 MST 패턴(14)에 의해 결제가 수행될 것이다. 한편, 사용자가 이동통신 단말기를 좌측 또는 우측으로 기울여 POS 단말기에 접근시키는 경우에는 기판(10) 본체에 형성된 MST 패턴(14)에 의해 결제가 수행되므로 문제되지 않을 것이다. 한편, 연장부(11)에 형성된 MST 패턴(14)은 기판(10) 본체에 형성된 MST 패턴(14)으로부터 연장 형성될 수 있으나, 이와 개별적으로 형성하여 커플링을 통해 기능을 수행할 수도 있다. The substrate 10 may include an extension part 11 of a predetermined shape on one side. The extension part 11 represents a portion including a hole in the 12 o'clock direction of the substrate 10 in the aforementioned drawings, but it is not necessary to include the hole. The MST pattern 14 may be extended to the extension part 11, so that even if the user approaches the POS terminal by tilting the top or bottom of the mobile communication terminal, payment may be performed by covering all directions. . For example, when the extension unit 11 is disposed on the upper side of the mobile communication terminal and the user tilts the top of the mobile communication terminal to approach the POS terminal, the payment is performed by the MST pattern 14 formed in the extension unit 11. If the extension 11 is disposed at the lower side of the mobile communication terminal, when the user tilts the bottom of the mobile communication terminal to approach the POS terminal, payment may be performed by the MST pattern 14 formed on the extension 11. will be. On the other hand, when the user tilts the mobile communication terminal to the left or right to approach the POS terminal, the payment is performed by the MST pattern 14 formed on the main body of the substrate 10, so it will not be a problem. The MST pattern 14 formed on the extension part 11 may be formed to extend from the MST pattern 14 formed on the main body of the substrate 10, but may be formed separately to perform a function through coupling.
도 12는 기판(10) 상면에 형성된 WPC 패턴(17)을 나타내는 도면이며, 도 13은 하면에 형성된 WPC 패턴(17)을 나타내는 도면이다. FIG. 12 is a view showing a WPC pattern 17 formed on the upper surface of the substrate 10, and FIG. 13 is a view showing a WPC pattern 17 formed on the lower surface.
WPC 패턴(17)은 내부로 감기는 원형의 형상을 가지고 있는 것이 일반적이며, 턴 수가 많아질수록 무선충전의 효율이 높아진다. 따라서 정해진 기판(10)의 사이즈 하에 최대한 많은 턴 수를 갖는 것이 바람직하며, WPC 패턴(17)의 지름과 이를 둘러싸는 MST 패턴(14)의 횡방향 및 종방향과의 관계는 앞서 설명하였다. The WPC pattern 17 generally has a circular shape wound inside, and as the number of turns increases, the efficiency of wireless charging increases. Therefore, it is desirable to have as many turns as possible under the size of the substrate 10, and the relationship between the diameter of the WPC pattern 17 and the transverse direction and the longitudinal direction of the MST pattern 14 surrounding the same has been described above.
한편, WPC 패턴(17) 최내부 도전선의 안쪽에는 NFC 패턴(12)이 이격되어 연장 형성되는바, 이를 통해 NFC의 성능을 획기적으로 개선할 수 있음 역시 앞서 설명하였다. Meanwhile, the inner side of the innermost conductive line of the WPC pattern 17 extends the NFC pattern 12 to be spaced apart, and thus, the performance of the NFC can be significantly improved.
지금까지 설명한 NFC 패턴(12), MST 패턴(14) 및 WPC 패턴(17)은 도 14에 도시된 바와 같이 기판(10)의 연장부(11)를 통해 각각의 단자들(13, 16, 18)을 노출 형성할 수 있으며, 이를 통해 이동통신 단말기의 내부 부품과 전기적으로 연결될 수 있다. 또한, 본 발명의 일 실시 예에 따른 안테나 구조체(100)는 기판(10)에 온도 측정이 가능한 써미스터(Thermistor, 40)를 더 포함할 수 있는바, 이를 통해 기판(10)의 온도, 보다 구체적으로 NFC 패턴(12), MST 패턴(14) 및 WPC 패턴(17) 중 하나 이상의 온도를 측정할 수 있다. 그러나 써미스터(40)가 반드시 패턴의 상면에 형성되어야 하는 것은 아니다. 이러한 써미스터의 단자(43) 역시 연장부(11)를 통해 노출 형성될 수 있으며, 이를 통해 이동통신 단말기의 내부 부품과 전기적으로 연결되어 WPC 패턴(17)의 온도가 일정 온도 이상으로 상승한 경우 무선충전 기능을 차단할 수 있다. 도 15를 참조하면 기판(10) 상면에 형성된 써미스터(40)를 확인할 수 있으나, 이는 하나의 실시 예일 뿐이며 써미스터(40)의 형성 위치는 필요에 따라 다양하게 조절 가능하다. The NFC pattern 12, the MST pattern 14, and the WPC pattern 17 described so far are connected to respective terminals 13, 16, and 18 through the extension 11 of the substrate 10, as shown in FIG. 14. ) Can be exposed and can be electrically connected to internal components of the mobile communication terminal. In addition, the antenna structure 100 according to an embodiment of the present invention may further include a thermistor 40 capable of measuring the temperature on the substrate 10, through which the temperature of the substrate 10 may be more specific. The temperature of one or more of the NFC pattern 12, MST pattern 14 and WPC pattern 17 can be measured. However, the thermistor 40 does not necessarily have to be formed on the upper surface of the pattern. The terminal 43 of the thermistor may also be formed to be exposed through the extension part 11, and is electrically connected to the internal parts of the mobile communication terminal so that the wireless charging is performed when the temperature of the WPC pattern 17 rises above a certain temperature. You can turn off the function. Referring to FIG. 15, the thermistor 40 formed on the upper surface of the substrate 10 may be confirmed, but this is only one embodiment, and the formation position of the thermistor 40 may be variously adjusted as necessary.
또한, 쉴딩시트(20)의 상면에는 그라파이트 시트(50)가 더 적층될 수 있다. 도 16을 참조하면 이를 확인할 수 있는바, 열 전도성이 좋은 그라파이트 시트(50)에 의해 효과적인 열 방출이 가능하며, 그라파이트 시트(50)가 아닌 기타 열 전도성이 좋은 다른 시트를 이용할 수 있음은 물론이다. 여기서, 상기 그라파이트 시트(50)가 쉴딩시트(20)의 상면에 형성되는 것으로 설명하지만, 반드시 이에 한정되지 않고, 기판(10)의 하면에 그라파이트 시트(50)가 형성될 수도 있다.In addition, the graphite sheet 50 may be further stacked on the upper surface of the shielding sheet 20. Referring to FIG. 16, it can be confirmed that the effective heat dissipation is possible by the graphite sheet 50 having good thermal conductivity, and other sheets having good thermal conductivity other than the graphite sheet 50 may be used. . Here, the graphite sheet 50 is described as being formed on the upper surface of the shielding sheet 20, but is not necessarily limited thereto, the graphite sheet 50 may be formed on the lower surface of the substrate 10.
한편, 본 발명의 일 실시 예에 따른 안테나 구조체(100)는 동일한 기술적 특징을 포함하는 또 다른 실시 예인 안테나 구조체 제조방법으로 구현할 수 있다. 이하, 도 17을 참조하며 설명하도록 한다.On the other hand, the antenna structure 100 according to an embodiment of the present invention can be implemented by a method for manufacturing an antenna structure which is another embodiment including the same technical features. A description with reference to FIG. 17 is as follows.
우선, 기판(10)의 상면 또는 하면에 안테나 패턴을 형성한다(S210). 여기서 기판(10)은 PCB 또는 FPCB일 수 있으며, 안테나 패턴은 NFC 패턴(12), MST 패턴(14) 및 WPC 패턴(17) 중 하나 이상을 형성할 수 있으나, 결제와 무선충전 기능을 모두 수행하기 위해서는 모두를 동시에 형성하는 것이 바람직하다. 패턴 형성은 공지된 안테나 패턴 형성 방법을 이용할 수 있다. First, an antenna pattern is formed on the top or bottom surface of the substrate 10 (S210). Here, the substrate 10 may be a PCB or an FPCB, and the antenna pattern may form at least one of the NFC pattern 12, the MST pattern 14, and the WPC pattern 17, but performs both payment and wireless charging functions. In order to do this, it is preferable to form all at the same time. Pattern formation can use a well-known antenna pattern formation method.
이후, 기판(10) 상면에 어트랙터(30)를 적층한다(S220). 여기서 어트랙터는 자성체가 포화되어 자기장이 바깥으로 퍼지고 그에 따라 발생하는 통신 효율의 저감(일종의 통신장애)을 방지하기 위한 구성으로써, 자기 흐름을 원활하게 하기 위해 고 포화 자화 값을 갖는 금속 성분으로 형성해야 하는바, 아몰포스(Amorphous) 성분을 함유하는 금속으로 형성함이 바람직하며, 상기 S210 단계에서 안테나 패턴이 형성되지 않은 부분에 적층함으로써 두께 증가를 방지함이 바람직하다. Thereafter, the attractor 30 is stacked on the upper surface of the substrate 10 (S220). The attractor is configured to prevent the decrease of communication efficiency (a kind of communication disturbance) caused by the saturation of the magnetic material and the magnetic field spreading outward, and is formed of a metal component having a high saturation magnetization value to smooth the magnetic flow. It should be, it is preferable to form a metal containing an amorphous (Amorphous) component, it is preferable to prevent the increase in thickness by laminating on the portion where the antenna pattern is not formed in the step S210.
어트랙터(30)를 적층했다면, 이후, 쉴딩시트(20)를 어트랙터(30) 상면에 적층한다(S230). 여기서 쉴딩시트(20)는 나노 크리스탈층(25)을 포함할 수 있으며, 나노 크리스탈층(50)에 의해 안테나 복합체(100) 전체 두께가 얇아지는 효과를 얻을 수 있다. If the attractor 30 is laminated, the shielding sheet 20 is then laminated on the attractor 30 (S230). Here, the shielding sheet 20 may include a nano crystal layer 25, and the entire thickness of the antenna composite 100 may be reduced by the nano crystal layer 50.
나노 크리스탈층(25)에 대하여 보다 상세히 설명하면, 나노 크리스탈층(25)은 제1 내지 제N(여기서 N은 양의 정수) 나노 리본이 접착제를 통해 적층된 구조를 나타낼 수 있으며, 접착제를 통해 적층된 구조이므로 위에서부터 아래로 적층하여 제조하는 방법 또는 아래서부터 위로 적층하여 제조하는 방법 중 어느 것을 이용해도 무방하다. In more detail with respect to the nano-crystal layer 25, the nano-crystal layer 25 may have a structure in which the first to N-th (where N is a positive integer) nano ribbon is laminated through an adhesive, Since it is a laminated structure, you may use the method of manufacturing by laminating | stacking from the top from the bottom, or the method of manufacturing by laminating from the bottom up.
한편, 나노 크리스탈층(25)은 Fe 93.4%, Si 4.86%, Cu 1.74%의 조성 함량을 나타내도록 제작하는 것이 바람직하나, 필요에 따라 일부 성분을 더 포함할 수 있으며, 조성 함량을 조절할 수 있음은 물론이다. On the other hand, the nano crystal layer 25 is preferably manufactured to exhibit a composition content of Fe 93.4%, Si 4.86%, Cu 1.74%, but may further include some components as necessary, the composition content can be adjusted Of course.
마지막으로, 쉴딩시트(20) 상면에 그라파이트 시트(50)를 적층한다(S240). 열 전도성이 좋은 그라파이트 시트(50)에 의해 효과적인 열 방출이 가능하며, 그라파이트 시트(50)가 아닌 기타 열 전도성이 좋은 다른 시트를 이용할 수 있음은 물론이다. 여기서, 상기 그라파이트 시트(50)는 기판(10)의 하면에 형성될 수도 있다.Finally, the graphite sheet 50 is laminated on the shielding sheet 20 (S240). The thermally conductive graphite sheet 50 enables effective heat dissipation, and other sheets having good thermal conductivity other than the graphite sheet 50 may be used. Here, the graphite sheet 50 may be formed on the bottom surface of the substrate 10.
중복서술을 방지하기 위해 자세히 설명하지는 않았지만, 앞서 설명한 본 발명의 일 실시 예에 따른 안테나 구조체(100)의 모든 기술적 특징은 안테나 구조체 제조방법에 모두 적용될 수 있다. Although not described in detail in order to prevent duplication, all technical features of the antenna structure 100 according to the embodiment of the present invention described above may be applied to all methods of manufacturing the antenna structure.
한편, 상기 S210 내지 S240 단계는 안테나 구조체 제조방법의 대표적인 단계만을 추출하여 설명한 것이며, 각 단계 사이에는 부가적인 단계들이 더 포함될 수 있다. 예를 들어, 접착제를 도포하는 단계, 기판(10) 하면에 완충제를 부착하는 단계, 써미스터(40)를 부착하는 단계, 커버 필름을 부착하는 단계, 상단 캐리어 필름을 부착하는 단계 등과 같이 안테나 구조체(100)의 개별적인 구성에 포함되는 세부 구성을 형성하는 단계들을 더 포함할 수 있음은 물론이다.Meanwhile, steps S210 to S240 are described by extracting only representative steps of the method of manufacturing an antenna structure, and additional steps may be further included between each step. For example, an antenna structure (such as applying an adhesive, attaching a buffer to a lower surface of the substrate 10, attaching a thermistor 40, attaching a cover film, attaching an upper carrier film, etc.) Of course, it may further include the step of forming a detailed configuration included in the individual configuration of 100).

Embodiments of the invention described above are disclosed for purposes of illustration, and the invention is not limited thereto. In addition, one of ordinary skill in the art of the present invention will be able to make various modifications and changes within the spirit and scope of the present invention, and such modifications and changes should be regarded as falling within the scope of the present invention.
