A multibeam analogue former of several two-dimensional radiofrequency beams of continuously variable sizes and/or aiming directions for a reconfigurable two-dimensional active array antenna, includes a first set of analogue multibeam formers of fixed one-dimensional beams, of identical structure, superposed and connected at the output to rows of elementary radiating feeds of a planar antenna array in a first axial direction X. The analogue multibeam former comprises a second set of second one-dimensional analogue formers of radiofrequency beams that are continuously variable in size and/or in aiming direction in second angular aiming directions By along a second axial direction Y. Each second analogue former is formed by a divider with a single input and R output branches in transmission mode, each output branch of the divider including an amplitude and phase control point. Each second analogue former of the second set is connected to at least one access column of the first set of first analogue formers, an access column being formed by R access terminals to the input channels of the same rank j of the first analogue formers.
