여기서 상기 '안테나 패턴(110)'이란 하나의 안테나 역할을 수행할 수 있는 구성으로서, 그 자체로 전파를 송수신할 수 있는 방사 슬롯 패턴을 의미한다. Here, the 'antenna pattern 110' is a configuration capable of performing one antenna role, and means a radiation slot pattern capable of transmitting and receiving radio waves by itself.
이러한 상기 '안테나 패턴'은 복수 개의 방사 슬롯 패턴을 포함할 수 있는데, 위에서도 살펴보았듯이, 양의 신호 성분으로 동작하는 복수 개의 방사 슬롯 및 음의 신호 성분으로 동작하는 복수 개의 방사 슬롯 패턴을 포함하는 형태로 구현될 수 있다. The 'antenna pattern' may include a plurality of radiation slot patterns.

여기서 상기 둘 이상의 안테나 패턴(310)들은 동일한 형태로 형성되기 때문에 동일한 안테나 특성을 나타내며, 특히 동일한 주파수 대역에서 동작한다.Since the two or more antenna patterns 310 are formed in the same shape, the two or more antenna patterns 310 have the same antenna characteristic, and operate in the same frequency band.
따라서, 본 발명의 일 실시예에 따른 방사 슬롯부(100)는, 동일한 주파수 대역에서 동작하는 상기 둘 이상의 안테나 패턴(310)들을 '동일 주파수 대역의 서로 다른 데이터를 송수신하기 위한 용도'로 활용할 수 있으며, 이를 통해 MIMO(Multiple Input Multiple Output)를 구현할 수도 있다. 또한, 본 발명의 일 실시예에 따른 방사 슬롯부(100)은 슬롯 패턴의 변화만으로도 둘 이상의 안테나 패턴을 형성할 수 있으므로, 추가적인 도체 소자를 설치하지 않아도 MIMO를 구현할 수 있다.Accordingly, the radiation slot unit 100 according to an embodiment of the present invention may utilize the two or more antenna patterns 310 that operate in the same frequency band as 'use for transmitting and receiving different data in the same frequency band'. In this case, a multiple input multiple output (MIMO) may be implemented.

(참고로, 안테나 패턴의 길이가 작아질수록 고주파 대역에서 동작하고, 안테나 패턴의 길이가 커질수록 저주파 대역에서 동작한다.)Since the two or more antenna patterns 410 and 420 are formed in different shapes, the two or more antenna patterns 410 and 420 exhibit different antenna characteristics, and in particular, operate in different frequency bands. (For reference, the smaller the length of the antenna pattern operates in the high frequency band, the larger the length of the antenna pattern operates in the low frequency band.)
따라서, 본 발명의 일 실시예에 따른 방사 슬롯부(100)는, 서로 다른 주파수 대역에서 동작하는 상기 둘 이상의 안테나 패턴(410, 420)들을 이용하여 다중 대역(Multi-band) 안테나를 구현할 수 있다. 또한, 본 발명의 일 실시예에 따른 방사 슬롯부(100)은 슬롯 패턴의 변화만으로도 둘 이상의 안테나 패턴을 형성할 수 있으므로, 추가적인 도체 소자를 설치하지 않아도 다중 대역 특성을 구현할 수 있다.Accordingly, the radiation slot unit 100 according to an embodiment of the present invention may implement a multi-band antenna using the two or more antenna patterns 410 and 420 operating in different frequency bands. . In addition, since the radiation slot unit 100 according to an embodiment of the present invention can form two or more antenna patterns only by changing the slot pattern, it is possible to implement multi-band characteristics without installing additional conductor elements.
한편, 상기 방사 슬롯부(100)가 포함하는 둘 이상의 안테나 패턴(410, 420)들은 다양한 구조로 형성될 수 있으나, 바람직하게는 도 8과 같이 대칭 구조를 포함하는 형태로 형성될 수 있다. Meanwhile, two or more antenna patterns 410 and 420 included in the radiation slot part 100 may be formed in various structures, but preferably, may include a symmetrical structure as shown in FIG. 8.

이하, 도 9를 참조하여, 본 발명의 일 실시예에 따른 방사 슬롯부(100)가 급전부와 연결되는 예시를 살펴본다.Hereinafter, referring to FIG. 9, an example in which the radiating slot part 100 according to an embodiment of the present invention is connected to a feeding part will be described.

Referring to FIG. 9, this feeding form may be described. In the embodiment of FIG. 9, the radiation slot portion 100 includes a plurality of radiation slots that operate with positive signal components and a plurality of radiation slots that operate with negative signal components. A signal is supplied to a point where a plurality of radiating slots operating with the positive signal component and a plurality of radiating slots operating with the negative signal component are connected to each other.
참고로, 도 9의 실시예에서 상기 방사 슬롯부(100)는, 서로 다른 형상으로 형성되는(서로 다른 주파수 대역에서 동작하는) 3종류의 안테나 패턴을 포함하고 있다. 따라서, 도 9의 실시예에서는, 상기 3종류의 안테나 패턴들에 서로 다른 주파수 대역의 신호들(1.7 ~ 2.2 GHz 대역, 5.0 ~ 6.0 GHz 대역, 2.3 ~ 2.7 GHz 대역)이 급전되고 있다. For reference, in the embodiment of FIG. 9, the radiation slot part 100 includes three types of antenna patterns formed in different shapes (operating at different frequency bands). Therefore, in the embodiment of FIG. 9, signals of different frequency bands (1.7 to 2.2 GHz band, 5.0 to 6.0 GHz band, 2.3 to 2.7 GHz band) are fed to the three types of antenna patterns.

이하, 도 10 내지 도 12를 참조하여, 본 발명의 일 실시예에 따른 도체 표면 안테나의 성능을 좀 더 구체적으로 살펴본다. Hereinafter, the performance of the conductor surface antenna according to an embodiment of the present invention will be described in more detail with reference to FIGS. 10 to 12.

이상에서 살펴본 본 발명의 일 실시예에 따른 도체 표면 안테나는, 고이득(High antenna gain)의 안테나 패턴을 구현할 수 있으며, 고효율(High efficiency, 급전부에서 급전되는 에너지가 얼마나 효율적으로 방사되는 지를 나타내는 지표)의 안테나 패턴을 구현할 수 있다. 또한, 상기 도체 표면 안테나는 대역폭 특성이 매우 우수한 안테나를 구현할 수 있으며, 방사 패턴도 옴니(Omni-directional) 방사 패턴을 구현할 수 있다.

먼저 제품의 외관 및 구조만 살펴보더라도, 상기 도체 표면 안테나가 적용된 무선 공유기(도 10의 상단부)가 일반적인 무선 공유기(도 10의 하단부)에 비해 현저하게 적은 부피로 형성되는 것을 확인할 수 있으며, 외관상으로도 막대 형상의 다이폴 안테나를 포함하지 않으므로 더욱 단순하고 깔끔한 형태로 형성된 것을 확인할 수 있다. First, even if only look at the appearance and structure of the product, it can be seen that the wireless router (top end of FIG. 10) to which the conductor surface antenna is applied is formed in a significantly smaller volume than the general wireless router (lower end of FIG. 10). Since the rod-shaped dipole antenna is not included, it can be seen that it is formed in a simpler and cleaner form.
또한, MIMO 구현의 관점에서 살펴보아도, 일반적인 무선 공유기(도 10의 하단부)가 복수 개(3 개)의 안테나 소자를 포함하는 반면, 상기 도체 표면 안테나가 적용된 무선 공유기(도 10의 상단부)는 단지 하나의 도체면(200)만을 이용하여 MIMO를 구현하는 것을 확인할 수 있다. (참고로, 도 10에서는 '별도의 도체면'이 설치되었지만, 실시예에 따라서는 무선 공유기에 '기본적으로 구비되는 도체면'이 활용될 수 있다.)In addition, from the standpoint of MIMO implementation, a general wireless router (lower part of FIG. 10) includes a plurality of (three) antenna elements, while a wireless router (upper part of FIG. 10) to which the conductor surface antenna is applied is only provided. It can be seen that the implementation of MIMO using only one conductor surface 200. (In FIG. 10, a separate conductor surface is installed, but according to an embodiment, a conductor surface basically provided in the wireless router may be used.)
