Embodiments of the present invention provide an apparatus (200) for feeding an antenna array (207) comprising at least first and second antenna elements (2071, 2072). The apparatus comprises a first transmitting element (2011) configured to receive a first base band signal (202-i) and to feed a first feed signal (2041) to a first antenna element (2071), the first transmitting element (2011) comprising a first power amplifier (2031). The apparatus also comprises a second transmitting element (2012) configured to receive a second base band signal (2022) and to feed a second feed signal (2042) to a second antenna element (2072), the second transmitting element (2012) comprising a second power amplifier (2032). 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. |
