Title (EN) A LINEAR DIVERSITY ANTENNA
(FR) ANTENNE A DIVERSITE LINEAIRE
Abstract:
(EN) An antenna (30) for a vehicular radio terminal is disclosed. The antenna (30) includes two sections (32, 34) which are vertically oriented in a linear fashion. A third antenna section (36) can be added. The first antenna section (32) is adapted to be supported on the vehicle. An insulator (46) is added between the antenna sections (32, 34) to provide electrical insulation between the sections (32, 34). The multiple antenna sections can be used to provide reception of multiple communication signals or to provide diversity reception.
(FR) Cette invention se rapporte à une antenne (30) pour un terminal radio de véhicule, cette antenne (30) comprenant deux sections (32, 34) orientées verticalement de façon linéaire. Une troisième section d'antenne (36) peut être ajoutée. La première section d'antenne (32) est adaptée pour être placée en support sur le véhicule. Un isolateur (46) est ajouté entre les sections d'antenne (32, 34) pour assurer une isolation électrique entre elles. Ces sections d'antenne multiples peuvent être utilisées pour assurer la réception de signaux de communication multiples ou pour assurer une diversité de réception.
