1. A feed system for controlling the variable electrical tilt in the vertical plane of arrayed radiating elements of a multiband antenna, comprising a Butler matrix and at least one module including delay lines, the Butler matrix having N inputs and N outputs and hybrid couplers, each input being capable of receiving a radio signal monoband or multiband belong to any frequency band and each output being capable of transmitting the signal to at least one radiating element allowing an independent electrical tilt for each frequency band, at least one output of the Butler matrix is connected to the module, which links the at least one output to the respective radiating element, the module comprising:

  • a first stage of diplexers that receives the signal from said output and separates the signal into different frequency bands,a second stage of fixed-delay lines that applies a given electrical delay to the signals from the first stage within each frequency band,a third stage of variable phase shifters that introduces an adjusted phase shift of the signals from the second stage in each frequency band, anda fourth stage of diplexers that combines the signals from the third stage in the different frequency bands to transmit them to at least one radiating element.
