Abstract :
A Genetic Algorithm (GA) design methodology is presented for synthesizing multiband Artificial Magnetic Conductors (AMCs) with angular stability. The GA is used to optimize the Frequency Selective Surface (FSS) screen geometry and other design parameters for both multiband operation and stability with respect to the angle of illumination at each operating frequency. The design example presented demonstrates the multiband angular stability for a dual-band AMC at a GPS frequency of 1.575 GHz and a cell phone frequency of 1.96 GHz.
