Abstract (en)

[origin: EP1223638A2] The system has an electrically large group antenna with first and second antenna sub-groups (11,12) and a combination conductor network (13) with an input for an antenna power signal, outputs to the sub-groups, a phase shifter (14) for producing a phase shift between the output signals before the are fed to the sub-groups and an arrangement for compensating the phase shift in the beam path of the antenna beam radiated by the sub-groups.
