A multi-frequency antenna reflector (AR) for example for a telecommunications satellite comprises a reflector (R) equipped with a front face (FA) designed to reflect the electromagnetic beam waves belonging to at least two different frequency bands. The front face (FA) of the reflector (R) comprises a structure (ST) defining a three-dimensional pattern with revolution symmetry selected so as to shape the beams so they present essentially identical radiofrequency characteristics.
