A radiofrequency transmission/reception system comprising: • an array (308; 308a, 308b, 308c, 308d; 308a', 308b', 308c', 308d') of active antennas (1.1,...,1.n,...,1.N); • a device (3; 3a, 3b, 3c, 3d; 3a', 3b', 3c', 3d') for controlling the array of active antennas designed to: • receive a misalignement value (φ) from among several possible misalignements values (φi,..,φn); • control the active antennas (1.1,...,1.n,...,1.N) so as to transmit at least one beam (F; Fa, Fb, Fb, Fc) misaligned by a received misalignement (φ) relative to a default direction; • parasitic elements (6.1,...,6.n,...,6.N) associated respectively with at least some of the active antennas (1.1,...,1.n,...,1.N) of said array; and • driving means designed to selectively activate each of the parasitic elements so as to modify a directivity of the associated active antenna in order to reduce an energy consumption of the active antenna array; the driving means and the parasitic elements (6.1,...,6.n,...,6.N) being designed to reconfigure the active antennas of said array according to at least two distinct directivity states selected from a less directive state (S-MD) and a more directive state (S-PD); the driving means being designed to reconfigure certain active antennas of said array according to the less directive state (S-MD) and certain active antennas of said array according to the more directive state (S-PD) when the received misalignement value is at least between -35° and -55° or between +35° and +55°. • an array (308; 308a, 308b, 308c, 308d; 308a', 308b', 308c', 308d') of active antennas (1.1,...,1.n,...,1.N); • a device (3; 3a, 3b, 3c, 3d; 3a', 3b', 3c', 3d') for controlling the array of active antennas designed to: • receive a misalignement value (φ) from among several possible misalignements values (φi,..,φn); • control the active antennas (1.1,...,1.n,...,1.N) so as to transmit at least one beam (F; Fa, Fb, Fb, Fc) misaligned by a received misalignement (φ) relative to a default direction; • receive a misalignement value (φ) from among several possible misalignements values (φi,..,φn); • control the active antennas (1.1,...,1.n,...,1.N) so as to transmit at least one beam (F; Fa, Fb, Fb, Fc) misaligned by a received misalignement (φ) relative to a default direction; • parasitic elements (6.1,...,6.n,...,6.N) associated respectively with at least some of the active antennas (1.1,...,1.n,...,1.N) of said array; and • driving means designed to selectively activate each of the parasitic elements so as to modify a directivity of the associated active antenna in order to reduce an energy consumption of the active antenna array; the driving means and the parasitic elements (6.1,...,6.n,...,6.N) being designed to reconfigure the active antennas of said array according to at least two distinct directivity states selected from a less directive state (S-MD) and a more directive state (S-PD); the driving means being designed to reconfigure certain active antennas of said array according to the less directive state (S-MD) and certain active antennas of said array according to the more directive state (S-PD) when the received misalignement value is at least between -35° and -55° or between +35° and +55°.
