Title
(EN) A COMPACT ANTENNA FOR MULTIPLE FREQUENCY OPERATION
(FR) ANTENNE COMPACTE FONCTIONNANT EN MULTIFREQUENCES
Abstract
(EN) An antenna intended for use in mobile communication systems is constructed as a pair of conductive comb-shaped structures on a flat rigid substrate or a flexible sheet of substrate material. It can be designed to operate in two or more distinct frequency bands according to the specifications of the communication systems.
(FR) L'invention concerne une antenne destinée à être utilisée dans des systèmes de communication mobile, qui comporte deux structures conductrices en forme de peigne placées sur un substrat rigide plat ou sur une feuille flexible de matière de substrat. Elle peut être conçue de manière à fonctionner dans au moins deux bandes de fréquence distinctes en fonction des spécifications des systèmes de communication.
