Abstract

다중 대역에 대한 임피던스 매칭을 지원하는 내장형 안테나가 개시된다. 개시된 안테나는, 급전점과 전기적으로 결합되는 제1 도전 부재 및 접지와 전기적으로 결합되는 제2 도전 부재를 포함하는 임피던스 매칭부; 및 상기 제1 도전 부재와 전기적으로 결합되는 적어도 하나의 방사체를 포함하되, 상기 임피던스 매칭부의 제1 도전 부재 및 제2 도전 부재는 소정 거리 이격되어 커플링 매칭을 수행하며 미리 설정된 지점에서 전기적으로 결합된다. 개시된 안테나에 의하면, 다중 대역 설계 시 광대역 특성을 확보할 수 있으며 특히 고주파수 대역에서 효과적인 광대역 특성을 확보할 수 있는 장점이 있다.
