A Novel Genetic-Algorithm-based AMC Structure

摘要

In this paper, a novel genetic-algorithm-based AMC structure, which is made up of high-impedance frequency selective surface, is introduced. The aperture-coupled microstrip antenna using this structure has 10dB less back radiation and 3～4dB more gains than a conventional one. This structure has important reference value to the manufacture of antenna. Practical antenna is fabricated, and the measured results basically agree with the simulated well.
