Abstract

This paper presents single-band and multi-band Artificial Magnetic Conducting (AMC) surface designs that are shown to have significant bandwidth enhancement achieved by loading the substrate with a magnetic material. In both cases, a conventional AMC structure consisting of a High Impedance Frequency Selective Surface (HZ-FSS) is optimized using a Genetic Algorithm (GA) for maximum bandwidth. The single-band design operates at 2 GHz, while the multiband design has targeted resonant frequencies of 860 MHz, 1.575 GHz, and 1.88 GHz. These design examples serve to demonstrate that the inclusion of a modest amount of magnetic material within the substrate allows for improved bandwidth at all resonant frequencies.
