Planar Artificial Magnetic Conductor: Design and Characterization Setup in the RFID SHF Band

A novel design of planar Artificial Magnetic Conductor (AMC) based on a Frequency Selective Surface (FSS) for frequencies in the SHF RFID band is presented. A discussion about design parameters and the influence of dielectric substrate thickness on the operating band and on the bandwidth is analyzed. The designed AMC shows polarization angle independency. Its angular margin when operating under oblique incidence is also tested. The discussion is supported by a FEM simulation and measurements in anechoic chamber of the manufactured prototype, with a good agreement between simulations and measurements.
