| Popis: | The goal of this study is to propose a method to optimize the dimension and the position of complementary split ring resonator considered as a defect structure in the ground to obtain a dual-band antenna. Therefore, the ground of the antenna is graved by the optimized complementary split ring resonator through Particle Swarm Optimization method. The designed antenna operates in two bands, 2.4 GHz and 5 GHz. The area of the proposed antenna is reduced approximately by 81.3% compared to the conventional antenna alone without complementary resonators cell. Furthermore, the return loss is improved from − 15 to − 26 dB. As well, the gain and bandwidth are improved for the two resonance frequencies. |
