A method for controlling the radiation pattern of an antenna means (1) comprising N helically configured radiating elements (12 1-12N), where N is an integer greater than 1, an antenna system, comprising N helically configured radiating elements (12 1-12N), and a radio communication device including such an antenna system. In the method, at least one property of at least one received signal from at least one of the radiating elements (121-12N) is measured, and at least one of the parameters phase (.PHI.n) and amplitude (A n) for received signals and/or signals to be transmitted for at least one of the radiating elements (12 1-12 4) is controlled as a response to the measured property of said received signal. The antenna system comprises means (47, 45, 42 1-42N, 54 1-54N) for controlling at least one of the parameters phase (.PHI.n) and amplitude (An) for signals received and/or signals to be transmitted by at least one of the antenna elements (121-12N).
L'invention porte: sur un procédé de réglage du diagramme de rayonnement d'un système d'antennes (1) à N éléments rayonnants en hélice (121-12N), où N est un entier supérieur à 1; sur système d'antennes (1) à N éléments rayonnants en hélice (121-12N); et sur un dispositif de radiocommunication comportant ledit système d'antennes. Selon le procédé, on mesure au moins une propriété d'au moins un signal reçu par l'un au moins des éléments rayonnants (121-12N), puis on règle la phase ( phi n) et l'amplitude (An) d'un au moins des paramètres du signal reçu et/ou émis par l'un au moins des éléments rayonnants (121-12N) de l'antenne, puis on le règle en fonction de la mesure. Le système d'antennes (47, 45, 421-42N, 541-54N) comporte des moyens de réglage de la phase ( phi n) et de l'amplitude (An) d'un au moins des paramètres du signal reçu ou émis par l'un au moins des éléments rayonnants (121-12N) de l'antenne.
