본 발명은 무선전화기와 이동 통신 무선 전화기 및 PCS(Personal Communication Service) 등의 무선 기기에 설치되어 소정의 전파를 송신하고, 수신하는 무선 기기용 안테나에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antenna for a wireless device installed in a wireless telephone, a mobile communication wireless telephone, and a wireless device such as a PCS (Personal Communication Service) to transmit and receive a predetermined radio wave.
일반적으로 무선 기기는 무선 통신을 수행하기 위하여 안테나를 사용하고 있다.In general, a wireless device uses an antenna to perform wireless communication.
즉, 무선 기기들은 변조부에서 출력되는 고주파 신호를 안테나에 인가하여 공중으로 송신하고, 또한 공간을 통해 전송되는 소정의 전파를 안테나를 통해 수신하고 있다.That is, the wireless devices apply a high frequency signal output from the modulator to the antenna and transmit it to the air, and also receive a predetermined radio wave transmitted through the space through the antenna.
이러한 안테나의 송신 특성 및 수신 특성을 향상시키기 위해서는 송신 및 수신할 주파수에 따라 안테나의 임피던스와 송수신기의 임피던스를 상호간에 매칭시키고, 불필요한 방사를 방지하여 손실이 적도록 해야 된다.In order to improve the transmission characteristics and the reception characteristics of the antenna, the impedance of the antenna and the impedance of the transceiver should be matched with each other according to the frequency to be transmitted and received, and unnecessary radiation should be prevented so as to reduce the loss.
이러한 안테나에는 수신상태를 양호하게 하기 위한 수단으로 하단부내에 스프링을 내장하고 있는데, 스프링의 중심부에 합성수지의 센터 로딩(CENTER LOADING)과 톱 로딩(TOP LOADING) 및 보텀 로딩(BOTTOM LOADING)을 매개하고 이 로딩 표면에 코일을 감아 스프링을 연결한 센터(CENTER)타입과, 중심부에 센터 로딩을 매개하지 않고 일자로 스프링만을 구성한 난-센터(NON-CENTER)타입의 두가지 타입이 있다.These antennas have a spring built into the bottom of the antenna as a means to improve the reception condition.The center of the spring mediates the center loading, top loading, and bottom loading of the resin. There are two types of centers: coils wrapped around the loading surface and springs connected, and non-centers that consist only of springs without center loading.
제1도는 종래 안테나가 무선전화기 및 이동 통신 무선 전화기에 설치된 상태를 나타낸 사시도로, 무선통신을 수행하기 위한 무선기기(1) 예컨대,무선전화기 및 이동통신 무선 전화기와, 상기 무선기기(1)에 연결되어 신호를 송수신하기 위한 안테나(2)로 이루어진다.1 is a perspective view showing a state in which a conventional antenna is installed in a radio telephone and a mobile communication cordless telephone. The radio apparatus 1 for performing radio communication, for example, a radio telephone and a mobile communication cordless telephone, It is connected to the antenna 2 for transmitting and receiving signals.
제2도는 상기에서 설명한 두가지 타입의 안테나중 예컨대, 센터 타입의 안테나에 사용되는 센터로딩을 도시한 것으로, 제1도와 같은 안테나(2)의 하단부에 제2도와 같은 합성수지의 로딩(3)이 내장되는데, 이 로딩(3)표면에 코일(4)을 권선하여 코일(4)의 한쪽 끝은 로딩(3)에 형성된 구멍을 통해 일측의 제1스프링(5)에 납땜으로 연결함과 아울러 코일(4)의 다른 한쪽 끝은 로딩(3)에 형성된 다른 구멍을 통해 타측의 제2스프링(6)에 납땜으로 연결하여 양호한 특성의 신호를 수신하도록 하였다.FIG. 2 shows the center loading used in the above-described two types of antennas, for example, a center type antenna, and a synthetic resin loading 3 as shown in FIG. 2 is built in the lower end of the antenna 2 as shown in FIG. The coil 4 is wound around the surface of the loading 3 so that one end of the coil 4 is connected to the first spring 5 on one side by soldering through a hole formed in the loading 3 and a coil ( The other end of 4) was soldered to the second spring 6 on the other side through the other hole formed in the loading 3 to receive a signal of good characteristics.
그러나, 이와같은 종래 안테나에 있어서는, 제1,제2스프링(5)(6)의 중심부에 매개된 로딩(3)의 표면에 코일(4)을 권선하는 작업이 어려움은 물론 권선된 코일(4)과 제1,제2스프링(5)(6)을 납땜하기가 어려운 결점이 있었으며, 별도의 코일(4)을 사용하므로 원가가 증대되는 결점이 있었다.However, in such a conventional antenna, it is difficult to wind the coil 4 on the surface of the loading 3 mediated in the center of the first and second springs 5, 6, as well as the wound coil 4 ) And the first and second springs (5) and (6) were difficult to solder, and a separate coil 4 was used to increase the cost.
또한, 로딩(3)에 권선을 하기 위한 수단으로 아세탈을 사출하므로 불량이 많이 발생되며, 이에따른 손실(lose)이 발생되는 결점도 있었다.In addition, since acetal is injected as a means for winding the loading 3, a lot of defects are generated, and thus there is a drawback that a loss occurs.
본 발명은 이와같은 종래의 결점을 해결하기 위하여 안출한 것으로,종래와 같이 스프링의 중심부분에 매개된 로딩 표면에 별도의 코일을 권선하는 과정과 이 코일과 철심을 납땜하는 과정을 모두 삭제하고, 로딩 자체를 도체로 형성하여 자성체를 이용한 무선기기용 안테나를 제공하는데 그 목적이 있다.The present invention has been made to solve such a conventional drawback, and eliminates all the process of winding a separate coil to the loading surface mediated in the center of the spring and soldering the coil and the iron core as in the prior art, It is an object of the present invention to provide an antenna for a wireless device using a magnetic material by forming the loading itself as a conductor.
이와같은 목적을 달성하기 위한 본 발명은 로딩자체에 사출성형으로 나선형상을 만들고, 상기 로딩에 일차로 동도금을한 후 그위에 다시 이차로 니켈도금을 한 상태에서 상기 나선형의 톱니부분을 제거하여 이루어진 것을 특징으로 한다.In order to achieve the above object, the present invention is made by forming a spiral shape by injection molding on the loading itself, and removing the toothed portion of the spiral in the state of first nickel plating on the loading and then secondly nickel plating on the loading. It is characterized by.
이하, 본 발명 무선기기용 안테나의 바람직한 실시예를 첨부된 도면을 참고로 하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the antenna for a wireless device of the present invention will be described in detail as follows.
제3도는 본 발명 무선기기용 안테나의 나선형 철심부분을 도시한 것으로, 안테나의 제1,제2스프링(5)(6)사이에 매개되는 로딩(3)을 사출성형으로 나선형상으로 형성하며, 상기 로딩(3)에 일차적으로 동도금을 하고 그위에 이차적으로 니켈 도금을 실시한 후 로딩(3)의 톱니부분을 소정부분까지 제거하여서 구성된 것이다.3 shows a spiral core portion of an antenna for a wireless device of the present invention, wherein the loading 3, which is mediated between the first and second springs 5 and 6 of the antenna, is formed in a spiral shape by injection molding. First, copper plating is applied to the loading 3, and second nickel plating is performed on the loading 3, and then the teeth of the loading 3 are removed to a predetermined portion.
이와같이 구성된 본 발명은 먼저, 로딩(3)을 사출성형으로 제3도의 (a)와 같이 나선형상으로 제조한다.The present invention configured as described above firstly manufactures the loading 3 in a spiral shape as shown in FIG. 3 (a) by injection molding.
그리고 로딩(3)표면에 일차적으로 동을 도금한 후 그위에 다시 니켈을 도금한다.Then, copper is first plated on the surface of the loading (3), and then nickel is again plated thereon.
이와같이 로딩(3)표면에 동도금과 니켈도금을 하면 로딩(3)자체가 도체가 되어 송신되어 오는 신호를 양호하게 수신할 수 있게 된다.When copper plating and nickel plating are applied to the surface of the loading 3 in this way, the loading 3 itself becomes a conductor, so that a signal transmitted from the loading 3 can be well received.
이와같이 로딩(3)에 이차적으로 도금이 이루어진 상태에서 로딩(3)의 톱니부(7)를 소정부분까지 절단하면, 제3도의 (b)와 같이 절단된 부분에는 도금한 부분이 제거되고, 절단되지 않은 부분(빗금부분)에만 도금한 부분이 남아 있게 되어 이렇게 남아있는 도금부분에 의하여 기존의 코일이 권선된 것과 같은 기능을 수행하게 된다.When the teeth 7 of the loading 3 are cut to a predetermined portion in the state in which the plating is secondary to the loading 3 as described above, the plated portion is removed from the cut portion as shown in FIG. The plated portion remains only on the portion (not the hatched portion) that is not, thereby performing the same function as the existing coil is wound by the remaining plating portion.
따라서, 이상과 같은 본 발명에 의하면, 로딩(3)자체에 도금된 도체부분에 의하여 코일의 역할이 수행되므로 로딩(3)에 별도의 코일을 권선할 필요가 없어짐은 물론 코일과 스프링을 납땜할 필요도 없어져 작업이 용이해질 뿐만 아니라 코일을 사용하지 않아 원가를 절감할 수 있다.Therefore, according to the present invention as described above, since the role of the coil is performed by the conductor portion plated on the loading 3 itself, there is no need to wind a separate coil on the loading 3 as well as to solder the coil and the spring. Not only does it need to be eliminated, but it also saves money by not using coils.
그리고 상기와 같은 방법으로 CDMA(코드분할 다원 접속방식)에 유용하게 사용할 수 있음은 물론 세라믹을 이용한 고주파 인덕터용으로 사용할 수 있으며, 특히 SMD용으로 유용하게 사용할 수 있는 효과가 있다.In addition, it can be usefully used for CDMA (code division multiple access method) as described above, and can be used for high frequency inductors using ceramics, and especially for SMD.
