Abstract

1211111222222Embodiments of the present invention provide an apparatus (200) for feeding an antenna array (207) comprising at least first and second antenna elements (207 207). The apparatus comprises a first transmitting element (201 ) configured to receive a first base band signal (202 i) and to feed a first feed signal (204) to a first antenna element (207) the first transmitting element (201 ) comprising a first power amplifier (203). The apparatus also comprises a second transmitting element (201) configured to receive a second base band signal (202) and to feed a second feed signal (204) to a second antenna element (207) the second transmitting element (201) comprising a second power amplifier (203). A tapering control unit (205) is adapted to provide a tapering function between the first feed signal to the first antenna element and the second feed signal to the second antenna element.
