<p>An omnidirectional antenna (1) intended for use in two distinct frequency bands and adapted to be connected to a coaxial feed line (3) for a signal, comprising two multifrequency radiating assemblies (5, 6, 35, 36) arranged on top of each other so as to be at the same distance with respect to the connection point between said two radiating assemblies (5, 6, 35, 36) and said coaxial feed line (3), each of said multifrequency radiating assemblies (5, 6, 35, 36) comprising two dipoles (20, 21, 22, 23, 45, 46, 47, 48), each having the possibility to operate at at least two distinct frequency bands, said at least two distinct frequency bands comprising the transmission frequencies of said signal.</p> |
