Abstract (en)
[origin: EP2706613A1] The system has a Butler matrix output (74A) connected to a module (75A) to allow an independent electric tilt for each waveband. The module includes a stage of diplexers for separating a signal according to different wavebands and a stage of fixed delay lines to apply an electric delay to the signal in each frequency band. The module has a stage of variable phase-shifters to introduce an adjusted dephasing of the signal into each frequency band, and a fourth stage of diplexers to regroup the signals in the different frequency bands for transmitting the signals to a radiating element (76A). An independent claim is also included for a method for controlling a variable electric tilt in a vertical plane of networked radiating elements of a multi-band antenna.
