Description
본 발명은 도전성 재질을 이용한 안테나에 관한 것으로, 이동통신단말기와 같은 소형의 통신단말기의 케이스에 적합한 도전성 재질을 이용한 안테나 제조방법과 그 제조방법에 의해 제조되는 안테나에 관한 것이다. The present invention relates to an antenna using a conductive material, and relates to an antenna manufacturing method using a conductive material suitable for a case of a small communication terminal such as a mobile communication terminal and an antenna manufactured by the manufacturing method.
멀티미디어 통신기술의 급격한 발전은 다양하고 복합적인 기능을 갖는 이동전화단말기기가 가능하게 되었고, 이동전화의 특성을 감안하여 이동성을 고려하여 다양하고 복잡한 기능의 구현이 가능하면서도 단말기의 크기가 더욱 작아질 수 있도록 하는 소형화가 가능하게 되었다. The rapid development of multimedia communication technology has made it possible to have a mobile terminal device having various and complex functions, and it is possible to realize various and complicated functions in consideration of mobility in consideration of the characteristics of the mobile phone, but also to reduce the size of the terminal. The miniaturization to make it possible.
특히 이동통신단말기의 로드형 안테나, 헬리컬 안테나의 경우 기기본체의 외부로 노출되어 설계됨에 따라서 사용자의 휴대에 장애요소로 작용함은 물론 사용으로 인한 잦은 파손 및 고장을 발생시키는 경우 많고, 그 구조가 복잡하여 안테나를 설계 하기위한 제한적인 요소로 작용함은 물론 소형화를 위한 이동통신단말기의 설계에 어려움을 겪게 된다. In particular, the rod-type antenna and helical antenna of the mobile communication terminal are designed to be exposed to the outside of the main body of the device, which not only acts as a barrier to the user's portable but also causes frequent breakage and failure due to use. Due to its complexity, it acts as a limiting factor for designing antennas, and also causes difficulties in designing mobile communication terminals for miniaturization.
또한 다양한 주파수대가 적용되는 이동통신단말기인 경우에는 각 사용 주파수 대역을 잡아주기 위한 안테나를 각각 구성하여 설계하기 위해서는 안테나가 설계되기 위한 공간을 필요로 하기 때문에 단말기의 크기가 커지거나, 이에 따라 그 구조가 변경되어야 하는 등 제한적 요소가 발생하게 된다.In addition, in the case of a mobile communication terminal to which various frequency bands are applied, the size of the terminal is increased because the space for the antenna is required to design and configure the antenna for each frequency band to be used. The limiting factor arises, such as
이에 안테나를 기기본체에 내장시키는 인몰드(IML) 방식의 안테나가 적용된 이동통신단말기가 상용화되고 있다.Accordingly, a mobile communication terminal using an in-mold (IML) type antenna for embedding the antenna in a device body has been commercialized.
인몰드 안테나는 DMB, DVB-H, FM 라디오 안테나 등과 같은 방송용 안테나, GPS, 블루투스와 같은 특성확보가 어려운 SUB안테나, N.F.C(Near Field Communication)솔루션으로 적합하다.In-mold antenna is suitable for broadcasting antennas such as DMB, DVB-H and FM radio antennas, SUB antennas such as GPS and Bluetooth, and N.F.C (Near Field Communication) solutions.
인몰드 안테나란, 인몰드 사출방식을 이용하여, 인몰드 필름에 안테나를 구현하여 사출공정을 통해 케이스와 안테나를 동시에 구현한 것으로, 케이스에 내장된 안테나를 말한다.An in-mold antenna is an in-mold injection method that implements an antenna on an in-mold film and simultaneously implements a case and an antenna through an injection process, and refers to an antenna embedded in a case.
인몰드 안테나는 단말기 케이스내부에 안테나를 구성하게 됨에 따라서, 다음과 같은 장점을 갖는다.As the in-mold antenna is configured to the antenna inside the terminal case, it has the following advantages.
(a). 안테나적 특성 구현에 있어, 단말기 메인 보드상에 별도의 안테나 구현을 위한 영역이 필요하지 않다.(a). In the implementation of the antenna characteristic, an area for implementing a separate antenna on the terminal main board is not needed.
(b). 단말기의 외곡에 안테나를 구현하게 됨에 따라서 안테나 특성 구현을 위한 체적이 넓어져 특성 구현이 용이하다. (b). As the antenna is implemented on the outer surface of the terminal, the volume for the antenna characteristic is widened, thereby facilitating the characteristic implementation.
(c). 메인안테나만을 구현하기에는 일반 사출 대비 인몰드 사출비가 비싸나, 방송용 안테나(외장형)를 대비할 경우 가격적인 이득이 발생한다.(c). In-mold injection cost is high compared to general injection to implement main antenna alone, but there is a price advantage when compared to broadcasting antenna (external type).
(d). 안테나가 케이스내부에 있어 안테나 복제를 방지할 수 있다. (d). The antenna is inside the case to prevent antenna duplication.
이에 대비해서, 인몰드 안테나는 단말기 최외곽(사람 손에 안테나가 접함)에 안테나가 위치함에 따라 인체 영향을 많이 받을 수 있어 메인안테나로는 사용하기 용이하지 않으며, 일반 안테나 적용을 위해서는 일반적인 안테나 구성보다는 제조 가격이 상승하게 되는 단점이 있다.In contrast, the in-mold antenna can be affected by the human body as the antenna is located in the outermost part of the terminal (the antenna is in contact with the human hand), and thus it is not easy to use as the main antenna. Rather, there is a disadvantage that the manufacturing price will rise.
종래 인몰드 방식 안테나는 도 1에 도시된 바와 같이 인몰드 사출시 캐리어 필름(인몰드필름)에 전도성 잉크를 이용하여 안테나 형상으로 프린팅하여 사출과 동시에 안테나를 제작하였다.In the conventional in-mold antenna as shown in Figure 1 when the in-mold injection to the carrier film (in-mold film) using a conductive ink to print in the shape of the antenna to produce the antenna at the same time injection.
이와 같이 도전성 잉크를 프린팅하는 방법에서는 안테나 베이스가 플라스틱 재질이므로, 플라스틱의 변형이 일어나지 않는 온도 이하에서 작업을 해야 한다. In the method of printing the conductive ink as described above, since the antenna base is made of plastic, the work must be performed at a temperature at which plastic deformation does not occur.
따라서, 베이스에 형성되는 안테나 패턴은 저온용 페이스트를 사용하여 인쇄해야 하는데, 인쇄도, 접착성 등을 고려해서 페이스트를 선정해야 하므로 재료의 제약이 많다.Therefore, the antenna pattern formed on the base should be printed using a low temperature paste, but the paste should be selected in consideration of the printing degree, adhesiveness, etc., and thus there are many material restrictions.
또한, 도전성 잉크의 인쇄도 및 접착성을 위해 도전성 잉크 내에는 도전물질 뿐만 아니라 유기물이 첨가되는데, 도전성 잉크를 고온 처리하는 경우에는 유기물을 제거할 수 있으나, 저온 처리하는 경우에는 유기물이 그대로 남아 있게 된다. 안테나의 베이스로 폴리머 계열이 사용되므로 고온처리 할 수 없어 도전성 잉크 내의 유기물은 안테나 방사체가 형성된 후에도 그대로 남아있게 된다. 이로 인해 안테나 방사체로서 가장 중요한 전기 전도도가 낮아지게 되어 안테나 방사특성 열화를 가져올 수 있는 문제점이 있다.In addition, not only conductive materials but also organic substances are added to the conductive ink for printing and adhesion of the conductive ink. When the conductive ink is subjected to high temperature treatment, organic substances may be removed, but when the low temperature treatment is performed, the organic substance remains as it is. do. Since the polymer base is used as the base of the antenna, it cannot be subjected to high temperature, so that the organic material in the conductive ink remains even after the antenna radiator is formed. As a result, the most important electrical conductivity is lowered as the antenna radiator, which may cause degradation of antenna radiation characteristics.
또한, 3차원 형상의 안테나 베이스에 도전성 잉크를 프린팅 하는 것은 공정상 어려움이 있다.In addition, printing a conductive ink on a three-dimensional antenna base has a difficulty in processing.
또 다른 종래 방법으로는, 캐리어 필름에 스퍼터링(sputteting)공정으로 안테나 방사체를 형성하고, 안테나 방사체가 형성된 캐리어 필름을 이동통신 단말기 케이스 형태의 몰드 내에 삽입하여 사출함으로써, 상기 안테나 방사체가 형성된 캐리어 필름과 일체로 결합된 이동통신단말기를 구성한다. In another conventional method, an antenna radiator is formed by a sputtering process on a carrier film, and a carrier film having an antenna radiator is inserted into a mold of a mobile communication terminal case and injected, thereby forming a carrier film; The mobile communication terminal is integrally combined.
이와 같이 스퍼터링 공정을 통해 안테나 방사체를 형성하는 방법은 스퍼터링 공정을 통해 안테나를 구성하게 됨에 따라서 안테나와 단말기 보드와의 연결하는 부분에서 단자를 안테나에 납땜하지 못하고, 페이스트로 고정하여 진행하게 된다. As described above, in the method of forming an antenna radiator through a sputtering process, as the antenna is formed through the sputtering process, the terminal is not soldered to the antenna at the connecting portion between the antenna and the terminal board, and fixed by paste.
따라서 안테나 단자 고정에 문제가 발생하게 되며, 고정력이 약해 공정중 단자 이탈 가능성이 높다. Therefore, a problem arises in fixing the antenna terminal, and the fixing force is weak, so there is a high possibility of terminal detachment during the process.
또한, 안테나 단자 고정시 금형에서 단자를 잡아주기 때문에 밀어주는 과정에서 단자를 고정하기 위해 밀어주는 금형 힘 때문에 그 부분의 필름이 외곽이 밀리는 외관 불량이 발생하게 된다.In addition, since the mold is held by the mold when the antenna terminal is fixed, the mold force that is pushed to fix the terminal during the pushing process causes an appearance defect that the film of the portion is pushed outward.
본 발명은 단말기 케이스 내에 외부에 부착 또는 그 내부로 구성함에 있어 적합한 특성을 갖는 연성형 안테나 제공방법에 관한 것으로, 도전성 플라스틱(plastic), 도전성 필름(film), 메탈(metal)과 같은 전기적인 전도성을 가진 재질을 이용하여 방사특성이 좋은 안테나 방사체를 갖으며, 단말기 케이스에 구성함에 있어서 장착공간을 최대한 활용할 수 있는 안테나를 제공하고자 한 것이다.The present invention relates to a method for providing a flexible antenna having suitable characteristics in attaching to the outside or configuring the inside of the terminal case, and electrically conductive such as a conductive plastic, a conductive film, and a metal. It is intended to provide an antenna that has an antenna radiator with good radiation characteristics by using a material having the same, and maximizes the mounting space in the terminal case.
본 발명은 캐리어 필름의 적어도 일면에 압출 또는 압연공정을 통해 안테나 패턴이 형성된 도전성 필름을 성형시켜 안테나 시트(sheet)를 형성하는 과정을 포함하여 이루어지는 것을 특징으로 한다. The present invention is characterized in that it comprises a step of forming an antenna sheet by molding a conductive film having an antenna pattern formed on at least one surface of the carrier film through an extrusion or rolling process.
본 발명은 도전성 플라스틱을 이중사출 또는 인서트 사출공정을 통해 안테나 패턴이 형성된 안테나를 형성하는 과정을 포함하여 이루어지는 것을 특징으로 한다. The present invention is characterized in that it comprises a step of forming an antenna formed with an antenna pattern through a double injection or insert injection process of the conductive plastic.
본 발명은 안테나 패턴이 형성된 메탈을 캐리어 필름의 일 면 또는 양 면상에 프레스공정을 통해 부착시켜 필름형태의 안테나 시트를 형성하는 과정을 통해 이루어지는 것을 특징으로 한다. The present invention is characterized in that the metal is formed through the process of forming an antenna sheet in the form of a film by attaching a metal on which the antenna pattern is formed on one or both sides of the carrier film through a pressing process.
이와 같은 본 발명에 따르면, 이동전화 단말기내에 안테나를 구성함에 있어서, 단말기 케이스의 형상에 따라 구성하여 내외부 케이스면에 부착 가능하여 안테나를 구성하기 위한 공간을 최대한 활용할 수 있어, 단말기의 소형화를 위해 설계함에 있어서 유리하다.According to the present invention, in the configuration of the antenna in the mobile phone terminal, can be configured according to the shape of the terminal case can be attached to the inner and outer case surface to maximize the space for configuring the antenna, designed for miniaturization of the terminal It is advantageous in this case.
따라서 서로 다른 주파수대를 수신하기 위한 복수개의 수신 주파수를 포함하는 이동통신단말기의 경우 여러개의 안테나가 필요한 바, 본 발명과 같은 안테나를 이용하는 경우 안테나를 구성하기 위한 공간을 최대한 활용할 수 있게 됨에 따라 설계에 매우 유리하다.Therefore, in the case of a mobile communication terminal including a plurality of reception frequencies for receiving different frequency bands, a plurality of antennas are required. When using the antenna according to the present invention, the space for configuring the antenna can be maximized. Very advantageous.
또한, 본 발명은 도전성 필름, 도전성 플라스틱, 메탈 등의 도전성 재질을 이용하게 됨에 따라서 방사특성이 좋은 안테나 방사체를 갖도록 한다.In addition, the present invention is to use a conductive film, such as a conductive film, a conductive plastic, a metal to have an antenna radiator with good radiation characteristics.
또한 본 발명은 도전성 플라스틱을 이중사출 또는 인서트 사출과 같이 사출물로 방사체를 구성하게 됨에 따라 그 형상을 자유롭게 성형가능하여 단말기 케이스의 디자인 설계에 유리하다.In addition, the present invention is advantageous in designing the terminal case can be formed freely by forming the shape of the conductive plastic as the radiator, such as double injection or insert injection.

In the case of the antenna using the conductive film of the present invention, the conductive film may be implemented in one or two sides, and in a single layer or a laminated structure. The characteristics of the antenna can be corrected.
