摘要：
Metamaterials, which are composite materials constructed usually by periodic and artificial resonant structures, have been widely utilized in many fields including the antenna design. Quite different from popular methods of embedding an antenna inside a metamaterial or placing metamaterial plates in front of an antenna, this work explores using a metamaterial structure, the periodic split-ring resonator (SRR), to design radiation slots in a printed array antenna for high gain. A proposed array with 4x4 slots and working at 5.8GHz has been automated designed by using the Genetic Algorithm (GA) in conjunction with the parallel computation on a cluster. Both results of numerical simulations and measurements demonstrate, in comparison with an array using conventional rectangular slots, that the proposed array with SRR slots possesses almost the same impedance bandwidth, side-lobe and cross polarization level, but the gain is improved from 18.7 dBi to 19.6 dBi.
