Patent ID: 7183992

Claim:
A wideband antenna system capable of radiating or receiving radio-frequency signals in a given frequency band, comprising at least two substantially collinear radiating elements, wherein each element radiates in one frequency band, a first radiating element working in the [Fhinf, Fhsup] frequency band, a second radiating element working in the [Fminf, Fmsup] frequency band, and wherein, at the [hinge] frequencies, these two elements participate in the radiation, wherein, a third radiating element working in the frequency band [Fbinf, Fbsup], wherein, the radiating elements are connected to a power supply network comprising one input and three outputs respectively connected to the first, second, and third radiating elements by three transmission lines, and wherein, the power supply network comprises at least one bandwidth filter, one duplexer whose duplex gap corresponds to the band of the filter and one hybrid 3 dB power divider.
