Artificial magnetic conductors realized by planar array of loaded loop for antenna applications

New designs of artificial magnetic conductors (AMC), including dual-polarized and multiband AMC are realized by planar regular array of loaded loop over a ground surface. Multiband designs of AMC surfaces are proposed based on the use of loaded loop with different resonance lengths. In addition, dual-polarized AMC are realized by loops with different orientation, which create artificial magnetic conductors for both TE and TM polarizations. The approximate analytical models were developed to estimate the AMC surface response. FEKO electromagnetic simulator is also used for the fullwave analysis of presented configurations.
