摘要:A new compact reconfigurable antenna design based on multi-objective genetic algorithm optimization used in conjunction with method of moment and MATLAB analysis is presented. A novel patch antenna geometry that is well suited to frequency reconfigurability, achieved through the use of switches connecting metal portion to the ground plane. At a high level, the resulting antenna packs several narrow-band systems and each of these are activated/deactivated at will by means of particular switch states so that the (variable) performance requirements are satisfied. The resulting structure has very attractive characteristics, such as small size, space filling, and good Return Loss (at 50 ohm). The proposed antenna demonstrates reconfigurable frequency range from 1.7 GHz up to 2.7GHz
