摘要
采用遗传算法（Genetic Algorithm，简称GA）设计了一种新型的AMC结构，这种结构是由高阻频率选择表面形成的．此结构应用于缝耦合微带天线时，可使天线背瓣降低10dB，增益上升2-3dB．这对设计天线提供了重要的参考价值．制作了实际天线，测量结果和仿真结果基本吻合．
A 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 2 - 3dB 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.
