Title
(EN) BROADBAND INTERNAL ANTENNA USING ELECTROMAGNETIC COUPLING HAVING SPIRAL STRUCTURE
(FR) ANTENNE INTERNE À LARGE BANDE UTILISANT UN COUPLAGE ÉLECTROMAGNÉTIQUE À STRUCTURE SPIRALE
(KO) 스파이럴 구조의 전자기 결합을 이용한 광대역 내장형 안테나
Abstract
(EN) Disclosed is a broadband internal antenna using an electromagnetic coupling having a spiral structure. The disclosed antenna comprises: a first electrically conductive member which is electrically connected to an electrical power point; a second electrically conductive member which is electrically connected to ground at a predetermined distance from the first electrically conductive member; at least one spiral cell which is coupled to the first electrically conductive member and the second electrically conductive member, between the first electrically conductive member and the second electrically conductive member, and which comprises at least two spiral arms; and an emitter which extends from the second electrically conductive member. The disclosed antenna has the advantage of ensuring broadband and multi-band characteristics since a more adequate amount of coupling can be ensured in a restricted space.
(FR) L'invention concerne une antenne interne à large bande utilisant un couplage électromagnétique à structure spirale. L'antenne décrite comprend : un premier élément électriquement conducteur électriquement connecté à un point d'alimentation électrique; un second élément électriquement conducteur électriquement connecté à la terre à une distance prédéterminée du premier élément électriquement conducteur; au moins une cellule spirale couplée au premier élément électriquement conducteur et au second élément électriquement conducteur, entre le premier élément électriquement conducteur et le second élément électriquement conducteur, comprenant au moins deux bras de spirale; et un émetteur partant du second élément électriquement conducteur. L'antenne décrite offre l'avantage de garantir des caractéristiques de large bande et de bandes multiples en raison du fait qu'un degré de couplage mieux adapté peut être assuré dans un espace limité.
(KO) 스파이럴 구조의 전자기 결합을 이용한 광대역 내장형 안테나가 개시된다. 개시된 안테나는 급전점과 전기적으로 연결되는 제1 도전 부재; 상기 제1 도전 부재와 소정 거리 이격되며 접지와 전기적으로 연결되는 제2 도전 부재; 상기 제1 도전 부재 및 상기 제2 도전 부재 사이에 상기 제1 도전 부재 및 상기 제2 도전 부재와 결합되어 적어도 두 개의 스파이럴 아암을 포함하는 적어도 하나의 스파이럴 셀; 및 상기 제2 도전 부재로부터 연장되는 방사체를 포함한다. 개시된 안테나에 따르면, 제한된 공간 내에서 보다 충분한 커플링량을 확보할 수 있어 광대역 및 다중 대역 특성을 확보하는데 유리한 장점이 있다.
