Abstract :
A novel structure composed of frequency selective surface printed elements implemented on a grounded dielectric slab is proposed for the design of wideband artificial magnetic conductors. In this design, a printed cross with a slot at the center is combined with an L-shaped unclosed rectangular loop, which enables to obtain a wideband high impedance surface. The bandwidth of the surface covers almost the entire X-band for a wide range of the incident angle of plane wave excitation for both the TE and TM polarizations. Commercial software EMPiCASSO is used for the full-wave analysis of the proposed high impedance surfaces.
