Abstract

A metasurface (MTS) can be characterized in terms of dispersion properties of guided waves and surface waves. By engineering the rich dispersion relations, setting particular boundary conditions, and selecting proper excitation schemes, multiple adjacent resonance modes can be excited to realize the wideband operation of low-profile MTS antennas. We introduce the operating principles of typical dispersion-engineered MTS antennas, and review the recent progress in dispersion-engineered MTS antenna technology. The miniaturization, circular polarization, beam-scanning, and other functionalities of MTS antennas are discussed. The recent development of MTS antennas has not only provided promising solutions to the wideband and low-profile antenna design but also proven great potential of MTS in developing innovative antenna technologies.
