Abstract: A method and a system for a multiband, dual polarization, and switch mode beamforming antenna for a small cell base station are disclosed. The disclosed system for a multiband, dual polarization, and switch mode beamforming antenna for a small cell base station may include: a dielectric substrate comprising a ground plane on which an antenna is disposed; a vertically polarized antenna reflector disposed on the dielectric substrate to be vertical thereto, and configured to induce forming of a vertically polarized beam; a vertically polarized antenna parasitic reflector that is a reconfigurable frequency selective reflector provided in a polyhedral structure for forming the vertically polarized beam; a horizontally polarized antenna reflector disposed on the dielectric substrate to be horizontal thereto and configured to induce forming of a horizontally polarized beam; and a plurality of switches configured to adjust a radiation mode of the vertically polarized beam and a radiation mode of the horizontally polarized beam.
