Abstract
In this paper, a simple planar meander-line tag antenna for RFID application at UHF band designed and optimized using genetic algorithms (GA). The meander-line tag antenna dimensions were optimized and evaluated using GA in collaboration with NEC-2 source code. Configuration of optimal antenna with excellent impedance value at 900 MHz frequency band was found within the maximum generation. The simulated input impedance of the GA-optimised tag antenna has shown good agreement with the targeted impedance value. Moreover, the capabilities of GA are shown as an efficient optimisation. tool for selecting globally optimal parameters to be used in simulations with an electromagnetic antenna design code, seeking convergence to designated specifications.
