본 발명은 평면형 도파관을 이용한 다이폴 안테나에 관한 것으로, 더욱 상세하게는 인쇄회로기판의 상/하면에 상호 대칭적으로 위치하는 평면형 도파관이 상호 연결된 구조로 적어도 하나의 차단 주파수를 가지는 일체형 평면 도파관과 정합 기능을 가지는 전송선을 통해 급전되어 낮은 복사 손실과 우수한 신호 전송 특성을 가지는, 평면형 도파관을 이용한 다이폴 안테나에 관한 것이다.
일반적으로, 통신시스템에서 평면형 안테나와 평면형 도파관을 사용하는 것은 통신 시스템의 가격을 낮추고, 소형/경량화를 추구하기 위함이다. 이때, 평면형 안테나와 평면형 도파관은 PCB(Printed Circuit Board) 또는 LTCC(Low Temperature Co-fired Ceramic) 등의 무기재료 또는 유기재료의 인쇄회로기판을 이용하여 구현될 수 있다.
특히, 평면형 안테나 중에서 다이폴(dipole) 안테나는 전방향(omni directional) 복사 특성을 가지기 때문에 통신 시스템용 안테나로서 주로 사용되었다. 그런데, 다이폴 안테나는 평형 기능을 가지는 급전선이 필요하지만, 일반적으로 통신 시스템용 부품은 불평형 회로로 구성되어 있다.
따라서, 다이폴 안테나에 급전되는 불평형 특성을 가지는 신호를 평형 특성을 가지는 신호로 변환해야 한다. 이 기능을 하는 것이 발룬(balun)이다. 발룬이 없으면 다이폴 안테나의 동분극(copolarization) 복사 특성 뿐만 아니라, 크로스 분극(cross polarization) 특성이 나빠진다.
특히, 통신 시스템의 성능 향상을 위하여 분극 다이버시티(polarization diversity)와 같은 방법을 이용하는 경우가 많은데, 크로스 분극(cross polarization) 특성이 나쁘면 정상적으로 동작하는 통신 시스템을 구현하기가 어려워진다.
따라서, 복사 손실이 낮고 우수한 신호 전송 특성을 가지는 다이폴 안테나가 절실히 요구되고 있다.
본 발명은 상기 문제점을 해결하기 위하여 제안된 것으로, 인쇄회로기판의 상/하면에 상호 대칭적으로 위치하는 평면형 도파관이 상호 연결된 구조를 가져 적어도 하나의 차단 주파수를 가지는 일체형 평면 도파관과 정합 기능을 가지는 전송선을 통해 급전되어 낮은 복사 손실과 우수한 신호 전송 특성을 가지는, 평면형 도파관을 이용한 다이폴 안테나를 제공하는데 그 목적이 있다.

도 1 은 본 발명에 따른 평면형 도파관을 이용한 다이폴 안테나의 일실시예 전면도이다.
도 1에 도시된 바와 같이, 본 발명에 따른 평면형 도파관을 이용한 다이폴 안테나는, 인쇄회로기판의 유전체(11) 전면에 위치하는 하기와 같은 구성요소, 즉 안테나 패턴(14)을 급전시키기 위한 평면형 도파관(12), 폭이 서로 다른 적어도 하나의 평형 선로로 이루어져 상기 평면형 도파관(12)을 통해 급전된 신호를 정합하기 위한 정합부(13), 및 상기 정합부(13)를 통해 급전되어 신호를 송수신하기 위한 안테나 패턴(14)을 포함한다.

또한, 상기 평면형 도파관(12)은 일정한 폭과 높이를 가지며, 그 폭과 높이에 의하여 차단 주파수가 결정된다.

이때, 상기 안테나 패턴(24)은 인쇄회로기판 유전체(11)의 전면에 위치한 안테나 패턴(14)과 xy 좌표 축을 기준으로 x축 대칭을 이룬다.
또한, 유전체(11)의 유전율과 높이는 각 평면형 도파관(12, 22), 평형 선로(정합부(13, 23), 안테나 패턴(14, 24)의 폭과 길이를 결정하는 인자이므로, 유전율과 높이를 적절히 선택하여 신호 전송을 극대화시킬 수 있다.
도 3 은 본 발명에 따른 평면형 도파관을 이용한 다이폴 안테나의 복사 패턴을 나타내는 일예시도이다.
