Design and characterization of a planar Artificial Magnetic Conductor in the RFID SHF band

A novel design of planar Artificial Magnetic Conductor (AMC) for frequencies in the SHF RFID band is presented. The designed AMC is based on a Frequency Selective Surface (FSS) and shows polarization angle independency. Its angular margin when operating under oblique incidence is also tested. Design parameters are discussed with the support of FEM simulations and measurements in anechoic chamber of the manufactured prototype, with a good agreement between simulations and measurements.
