Abstract

A circularly-polarised quadrifilar helical antenna, operated at 2.4 GHz band and intended for the applications of satellite mobile communications, was designed and optimised using genetic algorithm. The antenna design was firstly attempted on an infinite ground plane and then optimised further on small size mobile handset. The performance of the GA-optimised antenna design was validated through a hardware realization in terms of VSWR, axial ratio and power gain. The attained results indicate that the optimal antennas met design objectives under several certain constraints. 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.
