Description

이동통신 단말기용 안테나 어셈블리{Antenna assembly for mobile device}Antenna assembly for mobile terminal {Antenna assembly for mobile device}

본 발명은 이동통신 단말기에 장착되는 안테나에 관한 것으로서, 기생안테나가 일체로 구비되고, FPCB를 이용한 이동통신 단말기용 안테나 어셈블리에 관한 것이다.The present invention relates to an antenna mounted on a mobile communication terminal, and is provided with a parasitic antenna integrally, and relates to an antenna assembly for a mobile communication terminal using an FPCB.

휴대전화, PDA, PMP 등과 같은 이동통신 단말기에는 외부와 무선으로 데이터를 전송할 수 있도록 안테나가 구비된다.Mobile communication terminals such as mobile phones, PDAs, and PMPs are equipped with antennas for transmitting data wirelessly with the outside.

통상 상기와 같은 이동통신 단말기에 구비되는 안테나는 금속판재를 금형으로 가공하여 제작되고 있다.Usually, the antenna provided in the mobile communication terminal as described above is manufactured by processing a metal plate into a mold.

그러나, 상기와 같이, 이동통신 단말기에 구비되는 안테나를 금속판재를 가공하여 제작해야 하므로, 제작이 번거롭고, 이동통신 단말기에 따라 다르게 제작되어야 하는 문제점이 있다.However, as described above, since the antenna provided in the mobile communication terminal must be manufactured by processing a metal plate, manufacturing is cumbersome, and there is a problem in that it is produced differently according to the mobile communication terminal.

즉, 종래기술에 따른 이동통신 단말기용 안테나가 금속판재를 절단, 절곡하는 과정을 거쳐서 제작되므로, 장착될 이동통신 단말기의 형상, 안테나가 취부될 부분의 형상에 따라 각각의 금형이 마련되어야 한다. 그리고, 안테나가 금속판재로 제작되므로, 안테나를 이동통신 단말기에 장착하는 과정에서 휘거나 접을 수 없으 므로, 이동통신 단말기에 안테나를 장착함에 있어서 공간적으로 많은 제약이 발생할 수 밖에 없다.That is, since the antenna for a mobile communication terminal according to the prior art is manufactured through a process of cutting and bending a metal plate, each mold must be prepared according to the shape of the mobile communication terminal to be mounted and the shape of the portion to which the antenna is to be mounted. In addition, since the antenna is made of a metal plate, the antenna cannot be bent or folded in the process of mounting the antenna on the mobile communication terminal, so that a lot of spaces inevitably arise in mounting the antenna on the mobile communication terminal.

또한, 데이터를 전송기하기 위한 메인안테나 이외에도, 상기 메인안테나의 성능을 향상시킬 목적으로 기생안테나가 구비될 수 있다. 그러나, 종래기술의 이동통신 단말기용 안테나에 따르면, 메인안테나와 마찬가지로, 기생안테나는 금속판재도 가공하여 이동통신 단말기에 장착해야 하므로, 제작과정뿐만 아니라, 이동통신 단말기에 장착하는 과정에서 상기 메인안테나와 별도로 장착해야 하므로, 많은 조립공수를 가질 수 밖에 없는 문제점이 있다.In addition to the main antenna for transmitting data, a parasitic antenna may be provided for the purpose of improving the performance of the main antenna. However, according to the antenna for a mobile communication terminal of the prior art, like the main antenna, the parasitic antenna must also be processed on a metal plate and mounted on the mobile communication terminal, so that the main antenna is not only manufactured but also mounted on the mobile communication terminal. Since it must be mounted separately, there is a problem that can have a lot of assembly labor.

한편, 상기와 같이 완성되는 이동통신 단말기용 안테나 어셈블리를 이동통신 단말기에 부착하기 위해서, 최하층에는 접착테이프(14)가 구비된다. 상기 접착테이프(14)를 이용하여, 이동통신 단말기의 일측, 예컨대 배터리 커버, 하우징 등을 안테나가 장착되는 캐리어(20)로 하여 이동통신 단말기에 부착된다.On the other hand, in order to attach the antenna assembly for a mobile communication terminal completed as described above to the mobile communication terminal, the lowermost layer is provided with an adhesive tape (14).

특히, 로우밴드부(11c)는 접철선(Ⅱ-Ⅱ선)을 중심으로 접히고, 접히는 부분이 캐리어(20)의 모서리에 위치하도록 함으로써, 이동통신 단말기에서 안테나가 설치되는 공간을 최소화 할 수 있다.Particularly, the low band part 11c is folded around the fold line (II-II line), and the folding part is located at the corner of the carrier 20, thereby minimizing the space where the antenna is installed in the mobile communication terminal. .
