Description

고분자 화합물을 이용한 케이스 삽입형 안테나 제조 방식 {A method manufacturing the PMA(Polymer Mixture in mold Antenna)type antenna which used a high polymer material compound}A method manufacturing the PMA (Polymer Mixture in mold Antenna) type antenna which used a high polymer material compound}

본 발명은 통신기기에 내장되는 안테나의 제조 방식에 관한 것으로, 더욱 상세하게는 휴대폰에 내장되는 안테나인 인테나의 제조 방식에 관한 것이다.The present invention relates to a manufacturing method of an antenna embedded in a communication device, and more particularly, to a manufacturing method of an antenna, which is an antenna embedded in a mobile phone.

초기에 개발된 휴대용 무선 통신기기는 도1과 같이 휩 안테나 또는 헬리컬 안테나를 사용하였으나, 최근에는 단말기 제품의 소형화 및 슬림화, 그리고 단말기의 원가절감을 위하여 단말기 내부에 안테나 패턴이 형성된 금속박막을 장착한 내장형 안테나(도2)를 주로 사용하고 있다. In the early days, the portable wireless communication device developed using a whip antenna or a helical antenna as shown in FIG. 1, but recently, a metal thin film having an antenna pattern formed inside the terminal is used for miniaturization, slimming, and cost reduction of the terminal product. The built-in antenna (Fig. 2) is mainly used.

또한 최근 세계 각국에서 전자파 인체 보호 기준을 제정하는 등 전자파가 인체에 미치는 영향에 대한 관심이 고조되고 있으며, 특히 휴대용 전화기의 경우 인체에 가장 근접하여 이용되기 때문에 휴대용 전화기에서 발생하는 전자파의 영향을 줄이기 위한 인체로의 방사가 적은 안테나 개발의 필요성이 강조되고 있다. In recent years, interest in the effects of electromagnetic waves on the human body has been increasing, such as enacting electromagnetic wave protection standards in many countries around the world. Especially, in the case of portable telephones, they are used in close proximity to the human body. The need for developing an antenna with low radiation to the human body is emphasized.

현재 휴대폰 인테나에 사용되는 안테나는 도3 과 같이 PC나 ABS등의 합성수지 재질의 캐리어(31)에 금속 프레스물로 성형한 안테나 패턴(32)을 열 융착하는 방법(33) 으로 안테나를 제작하였다.(stamping type) Currently, the antenna used in the cellular phone antenna is manufactured by a method 33 of thermally fusion bonding an antenna pattern 32 formed of a metal press to a carrier 31 made of synthetic resin such as PC or ABS as shown in FIG. 3. (stamping type)

그런데 현재 핸드폰 안테나는 다중 대역을 사용하고 있는데 다중 대역의 안테나의 성능을 확보하기 위해서는 무엇보다도 안테나 공간을 넓게 가져가는 것이 절대적인 요구 사항이지만 기존의 안테나 제조 방식으로는 안테나 공간 활용을 극대화 할 수 없는 단점이 있다. 이러한 단점 때문에 점점 더 소형화 및 슬림화가 요구되는 휴대폰 디자인의 추세에 맞는 안테나 공간의 축소와 성능 확보 조건을 충족시킬 수 없게 되었다.However, cell phone antennas are currently using multiple bands, but in order to secure the performance of multi-band antennas, it is an absolute requirement to take a wider antenna space, but conventional antenna manufacturing methods cannot maximize the utilization of antenna space. There is this. Due to these shortcomings, it is impossible to meet the requirements of reducing antenna space and securing performance, which is in line with the trend of mobile phone design, which is required to become smaller and slimmer.

이를 해결하기 위하여 안테나 패턴을 제외한 캐리어를 먼저 사출하고, 안테나 패턴에는 ABS 재질로 이중 사출한 후, 이를 도금액에 담그면 ABS 부분에만 도금액이 묻게 되는 MID(Molded Interconnect Device) 방식이 개발되어 안테나 공간의 증대로 인한 성능 확보에는 유리한 점이 입증되었으나, 이중 사출 후의 도금 작업으로 인해 제조 단가가 높은 단점과 기존의 휴대폰 캐이스 내부에 캐리어를 장착하는 방식을 여전히 사용하기 때문에 안테나 공간 제약 문제를 해결해야 하는 문제는 여전이 남아있게 된다. To solve this problem, the carrier except the antenna pattern is first injected, and the antenna pattern is double-injected with ABS material, and when it is immersed in the plating solution, a MID (Molded Interconnect Device) method is developed in which the plating solution is only buried in the ABS part, thereby increasing the antenna space. It has proved to be advantageous in securing performance, but it is still a problem to solve the antenna space limitation problem due to the high manufacturing cost due to the plating work after double injection and the use of the carrier mounted inside the existing cell phone casing. Will remain.

기존의 금속 프레스물로 성형하는 안테나는 모든 안테나 패턴을 케리어에 거치시키고 안테나 패턴 마다 열 융착으로 고정해야 하기 때문에 양산성이 떨어져 제조비가 높은 문제가 있고, 캐리어에 안테나 패턴이 형성되는 구조이기 때문에 설계상 공간적 제약을 많이 받으며, 패턴이 외부로 노출되어 있어 기술적인 보안유지가 힘들다.Since the antenna formed from the existing metal press is required to mount all antenna patterns on the carrier and fix them by heat fusion for each antenna pattern, there is a problem in that the manufacturing cost is high and the antenna pattern is formed on the carrier. Due to its spatial constraints, the pattern is exposed to the outside, which makes it difficult to maintain technical security.

따라서 본 발명은 상기와 같은 종래의 문제점을 해결하기 위한 것으로, 고분자 화합물을 이용하여 안테나 패턴을 형성하고, 다대 사출기(수직 사출기)에 고분자 화합물로 성형된 안테나 패턴을 놓고 사출한다. 이렇게 사출된 사출물을 휴대폰 케이스에 인몰드 사출을 하게 되면 휴대폰 케이스 일체형 안테나를 제조할 수 있다.Therefore, the present invention is to solve the conventional problems as described above, to form an antenna pattern using a polymer compound, and to place the antenna pattern molded of a polymer compound in a multiple injection molding machine (vertical injection machine) and eject. When the injection molded product is injected in-mold to the mobile phone case, the mobile phone case integrated antenna can be manufactured.

따라서 이러한 방식의 안테나는 휴대폰 케이스에 삽입되기 때문에 안테나의 공간적인 제약을 받지 않으면서도 휴대폰의 소형화 및 슬림화 디자인에 기여할 수 있고, 다중대역의 안테나 성능을 확보 할 수 있다. 또한, 안테나 제조 과정이 단순화 되기 때문에 제조비 절감 효과로 인한 가격 경쟁력을 높일 수 있고, 안테나 패턴이 외부에 노출되지 않기 때문에 안테나 설계 기술에 대한 보안을 유지할 수 있는 장점이 있다.Therefore, this type of antenna is inserted into the mobile phone case, so it can contribute to the miniaturization and slim design of the mobile phone without being restricted by the space of the antenna, and can secure the antenna performance of the multi-band. In addition, since the antenna manufacturing process is simplified, the cost competitiveness can be increased due to the reduction in manufacturing cost, and the antenna pattern is not exposed to the outside, thereby maintaining the security of the antenna design technology.

본 발명에서 제안하는 안테나는 도4 와 같이 고분자 화합물을 이용한 안테나 패턴(41)과 안테나 패턴을 넣어 사출한 사출물(42), 안테나를 휴대폰 전자회로부인 PCB와 연결하기 위한 컨텍트 단자(43), 다대 사출한 사출물을 안테나 케이스에 인몰드 방식으로 삽입한 케이스(44)로 구성된다. The antenna proposed in the present invention is an antenna pattern 41 using a polymer compound and an injection molded product 42 by inserting the antenna pattern as shown in FIG. 4, a contact terminal 43 for connecting the antenna to a PCB which is a mobile phone electronic circuit part, and many units. The injection molded product is composed of a case 44 inserted into the antenna case in an in-mold manner.

고분자 화합물은 PA나 PP, PC 등의 합성수지에 저융점 금속이 혼합되어 있는 형태의 화합물이며, 먼저 고분자 화합물로 안테나 패턴을 성형한다. 안테나 패턴 성형 후 안테나를 지지하기 위하여 안테나를 다대 사출기에 넣어 다대 사출 하면, 사출물 안에 안테나 패턴이 형성되어 안테나 패턴 자체를 보호할 수 있으며, 외부로 안테나 형상이 노출되지 않기 때문에 안테나 설계 기술을 보호할 수 있다. 이렇게 성형된 사출물에 전자회로부인 PCB와 연결하기 위한 컨텍트 단자를 삽입한 후, 이를 케이스에 인몰드 사출하게 되면 케이스에 안테나 컨텍트 단자만 도출되고, 나머지는 케이스에 삽입된 일체형 안테나를 제조할 수 있다.The polymer compound is a compound in which a low melting point metal is mixed with synthetic resins such as PA, PP, and PC, and first, an antenna pattern is formed from the polymer compound. After the antenna pattern molding, if the antenna is inserted into the injection molding machine to support the antenna, the antenna pattern is formed in the injection molding to protect the antenna pattern itself, and the antenna design technology is protected because the antenna shape is not exposed to the outside. Can be. After inserting the contact terminal for connecting with the PCB which is an electronic circuit part in the molded injection molding, and injecting it into the case, only the antenna contact terminal is derived from the case, and the rest can be manufactured with an integrated antenna inserted into the case. .
