Antenna Reconfiguration Using Metasurfaces

摘要：

　　The paper describes the designs of a frequency-reconfigurable,polarization reconfigurable and pattern reconfigurable antennas using metasurfaces(MS).The frequency-reconfigurable and polarization reconfigurable antennas are composed of a simple circular patch antenna or slot antenna as the source antenna and a circular MS with the same diameter,with both source antenna and MS implemented using planar technology.The pattern reconfigurable antenna is composed of a circular patch antenna as the source antenna and a semicircular MS with the same diameter.In all these reconfigurable antennas,the MS is placed directly atop of the source antenna,making the antenna very compact and low profile with a thickness of only 0.05λ0.By rotating the MS around the center with respect to the source antenna,the frequency,polarization or pattern of the reconfigurable antenna can be reconfigured.
