Title: Connecteur d'antenne pour equipement de radiocommunication
Inventor: SUNG WEONMO
IPC: H01Q1/24
Filed: 1999-05-31
Abstract: L'invention concerne un connecteur d'antenne destiné à un équipement de radiocommunication. Le connecteur convertit la résonance parallèle classique d'une antenne en une résonance série, grâce à une partie découpée plane formée sur le transformateur d'impédance ou sur la partie d'alimentation en signaux de l'antenne, sans modifier les caractéristiques de celle-ci, ce qui augmente sa largeur de bande. Il permet également de commander ou d'augmenter ladite largeur de bande en fonction de la structure du transformateur d'impédance. Il commande facilement et simplement la largeur de bande d'une antenne en modifiant la taille et la hauteur du transformateur, la surface utile de la partie découpée du transformateur ou le nombre de tours de l'antenne fixée sur le transformateur. Ce connecteur, qui peut donc être utilisé à diverses fréquences, compense efficacement et rapidement les variations de la fréquence centrale de l'antenne quand ces variations sont dues à un changement dans les conditions de l'environnement.
