The disclosure relates to a system comprising an antenna (ANT) divided in two symmetric parts. Each part comprises a respective radiation element (RE_1, RE_2). The system is arranged to feed a first signal into a first radiation element (RE_1) of a first part of the antenna (ANT), to generate a second signal, and to feed the second signal into a second radiation element (RE_2) of the second part of the antenna (ANT). The second signal is obtained by substantially inverting the phase of the first signal. The disclosure also relates to a cellular base station comprising such system, to a network of cellular base stations, to methods for reducing interferences, to a computer program for implementing such method, and to a storage medium storing such computer program.
