Description
본 발명은 아날로그 및 디지털 셀룰라폰, 개인휴대통신(PCS)폰 등 휴대가능한 전화기용 안테나에 있어서 종래 기술에 따른 헬리컬 구조 안테나의 특성을 개선하고 양산성을 증가시켜 저가격화를 유도하기 위한 것이다. 본 발명에 따른 세라믹 유전체를 이용한 휴대통신 단말기용 헬리컬 구조 안테나는 또한 일정한 유전율의 세라믹 헬리컬 안테나를 구현함으로써 성능이 변하지 않고 안정되게 유지할 수 있으며 크기를 대폭적으로 줄일 수 있다.The present invention is to improve the characteristics of the helical structure antenna according to the prior art in the antenna for portable telephones, such as analog and digital cellular phones, personal mobile communication (PCS) phones and to increase the mass productivity to induce low cost. The helical structure antenna for the mobile communication terminal using the ceramic dielectric according to the present invention can also be maintained stable without changing the performance and the size can be significantly reduced by implementing a ceramic helical antenna of a constant dielectric constant.
종래 기술에 따른 헬리컬 구조 안테나는 주로 탄성이 큰 금속을 사용하여 전기적으로 λ/4의 길이를 가지며 스프링 형태로 제작되어 모양의 변형, 파손 및 산화에 의한 성능의 저하를 방지하기 위해 외부에 플라스틱 계열의 비전도성 물질로 코팅한 후 사용되고 있지만 이와 같이 제작하기 위하여 사용되는 탄성이 큰 금속은 일반 구리 등에 비해 가격이 비싸다. 또한 외곽 부위를 동시에 정밀하게 코팅하는 것은 여러 공정이 필요하며 비교적 어려운 작업이다. 이러한 코팅 작업을 줄이기 위해 여러 가지 플라스틱 재질의 커버를 이용해 헬리컬 안테나부를 보호하는 형태도 사용되고 있으나 산화 방지가 되는 금속선을 사용하여야 한다고 하는 문제점이 있었다.The helical structure antenna according to the prior art has a length of λ / 4, mainly made of a highly elastic metal, and is made in the form of a spring to prevent deterioration of performance due to deformation, breakage, and oxidation of plastics. Although it is used after coating with a non-conductive material, the large elastic metal used to make it is more expensive than ordinary copper. In addition, precisely coating the outer area simultaneously requires several processes and is a relatively difficult task. In order to reduce the coating work, a form of protecting the helical antenna unit by using various plastic covers is also used, but there is a problem that a metal wire to prevent oxidation is used.
따라서, 본 발명에 따른 세라믹 유전체를 이용한 휴대통신 단말기용 헬리컬 구조 안테나는 상기와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 새로운 구조의 안테나로서 종래 기술에 비해 헬리컬 구조 안테나의 특성을 개선하고 양산성을 증가시켜 저가격화를 유도하기 위한 것이 주목적이다. 또한, 일정한 유전율의 세라믹에 헬리컬 안테나를 구현함으로써 성능이 변하지 않고 안정되게 유지할 수 있으며 크기를 대폭적으로 줄일 수 있는 세라믹 유전체를 이용한 휴대통신 단말기용 헬리컬 구조 안테나를 제공함에 그 목적이 있다.Therefore, the helical structure antenna for a mobile communication terminal using the ceramic dielectric according to the present invention is a new structure antenna designed to solve the problems of the prior art as described above. The main purpose is to increase the cost and induce lower prices. In addition, it is an object of the present invention to provide a helical structure antenna for a mobile communication terminal using a ceramic dielectric that can maintain a stable performance without changing the performance by implementing a helical antenna on a ceramic having a constant dielectric constant.
