Abstract

La présente invention concerne une unité d'antenne qui utilise une antenne cadre minuscule et qui comprend une antenne cadre minuscule (11) formée de façon sensiblement perpendiculaire à la surface de montage d'une carte de circuit imprimé (2), une configuration de masse (6) formée sur la surface de montage de la carte de circuit imprimé (2) et servant de doublet, et une section de circuit sans fil (12) montée sur la carte de circuit imprimé. Lorsqu'un conducteur est agencé de près, une augmentation de la fréquence de résonance de l'antenne cadre minuscule (11) en raison du conducteur est compensée en réduisant la fréquence de résonance du doublet (6), réduisant ainsi le défaut d'adaptation d'impédance entre l'antenne cadre minuscule (11) et le doublet (6) et la section de circuit sans fil (12).
