A circularly polarized radiating element includes at least one excitation aperture for a wave that is linearly polarized with what is referred to as an excitation first polarization, a frequency selective surface and a metasurface comprising a two-dimensional and periodic array of metasurface cells, the excitation aperture opening onto the metasurface, the metasurface cells all being oriented identically with respect to the excitation polarization and configured to: reflect an incident wave having the excitation polarization in order to form a reflected wave polarized with the excitation polarization, and depolarize and reflect the incident wave in order to form a reflected wave polarized with the orthogonal polarization, having a phase difference substantially equal to &#xb1;90&#xb0; with respect to the reflected wave polarized with the excitation polarization, and having an amplitude substantially equal to the amplitude of a wave radiated by the frequency selective surface, generated from the reflected wave polarized with the excitation polarization.
