Abstract
AbstractIn this paper, a novel genetic algorithm (GA)‐based AMC structure, which is made up of a high‐impedance frequency‐selective surface, is introduced. The aperture‐coupled microstrip antenna using this structure has 10‐dB less back radiation and 3–4‐dB more gain than a conventional one. This structure has important reference value for antenna manufacturing. A practical antenna is fabricated, and the measured results basically agree well with the simulated ones. © 2005 Wiley Periodicals, Inc.
