abstract = "Holographic impedance surfaces (HIS) have the potential to achieve multifunctional multiplexing. This letter proposes a low-profile scalar impedance surface antenna to achieve far-field multiplexing of different radial orbital angular momentum (OAM). The antenna is designed by holographic method, and the far-field scalar vortex beam of +1 mode at 30° and +2 mode OAM at -30° is realized by the regular arrangement of surface impedance. A monopole antenna is placed at the center of the surface to serve as the excitation source for the surface. A good surface impedance is obtained for the 3x3 mm2 square scalar cell at 17GHz operating frequency. The overall size of this antenna is 117x117 mm2. The reflection coefficient of this antenna is less than -10dB at 14.1-20.7 GHz and the theoretical, simulation results are presented.",
