An antenna array, in particular a traveling-wave antenna array, has an adjustable radiation pattern, having an antenna element that has a first feed terminal at one end of the antenna element and a second feed terminal at another end of the antenna element; a signal generation unit that is configured for generating a feed signal and for providing a feed signal at the first feed terminal of the antenna element and at the second feed terminal of the antenna elements; at least one signal conditioning unit that is electrically configured between the signal generation unit and one of the feed terminals and that is configured for matching the amplitude and/or the phase of the corresponding feed signal to a specified radiation pattern. Also described is a corresponding method.
