    Abstract: A multi-band metasurface antenna is described. The antenna includes a plurality of stacked metasurface layers for operation according to a respective plurality of separate and distant frequencies. Each metasurface layer presents a high impedance at frequencies that are different from the respective frequency. The metasurface layers are stacked according to a decreasing order of the respective frequencies, with the highest frequency closer to a bottom ground layer of the stack. The metasurface layers are separated by dielectric layers of equal permittivity. According to one aspect, the antenna includes two metasurface layers for respective operation according to a Ka-band and a W-band. According to another aspect, the antenna includes an integrated feed structure that includes respective inner conductors vertically arranged through the dielectric layers to make contact with respective feeder extensions that are in contact with the respective metasurface layers.
