Claims (10)
- 소정 길이를 갖는 스트립선로와 단락된 패치를 전자기적으로 결합하여 급전하는 구조로 이루어지고, 상기 스트립선로에서의 직렬공진과 상기 단락된 패치가 상기 스트립선로에 의해서 커플링되어 발생하는 병렬공진이 결합하여 넓은 주파수의 대역폭을 가지며, 접지면이 상기 스트립선로 및 상기 단락된 패치와 수직방향에 위치하는 것을 특징으로 하는 모노폴 안테나.
- 제1항에 있어서,상기 접지면이 상기 스트립선로 및 상기 단락된 패치와 수직방향에 위치하는 구조는,상기 스트립선로가 제2 유전체 기판의 일면에 형성된 소정 지름의 마이크로스트립 라인에 의해 급전되며, 상기 단락된 패치는 단락핀을 통하여 상기 제2 유전체 기판의 다른 면에 형성된 수직 접지판의 상단에 접속되는 구조인 것을 특징으로 하는 모노폴 안테나.
- 제2항에 있어서, 상기 제2 유전체 기판은,상기 스트립선로 및 상기 단락된 패치에 수직한 방향에 위치하는 것을 특징으로 하는 모노폴 안테나.
