Abstract

Ce système d'antenne à double entrée possède une première entrée qui permet une correspondance d'impédance sur une première gamme de fréquences et une seconde entrée qui assure une correspondance d'impédance sur une seconde gamme de fréquences. Cet agencement permet à une antenne à bande étroite de fonctionner et établit un état de correspondance en deux gammes de fréquences séparées. Un dispositif de couplage d'antenne sans connecteur (100) comprend un boîtier de protection métallique (102) dimensionné de manière à contenir une partie d'une radio portative (10) ayant une antenne intérieure et une première ligne de transmission. Un résonateur ou une ligne de transmission (119) montée sur le boîtier métallique de protection est positionnée adjacente à la première ligne de transmission lorsque la radio est dans le boîtier de protection métallique, et permet le couplage d'énergie entre le résonateur et la première ligne de transmission.
