Abstract
In this communication, Artificial Impedance Surfaces (AIS) based on patches from High Impedance Surface (HIS) are considered. The possibility to use the patch width as an additional degree of freedom for antennas design is investigated. Within the limitation of a single linear polarization, rectangular patches of this AIS allow adjusting the surface impedance value while keeping identical the in-phase reflection property of such metasurfaces on the same frequency range. With this approach, a bandwidth of 17% is achieved by using a dipole antenna over an AIS.
