The electronically steerable parasitic array radiator (ESPAR) antenna system is configured with one feed radiating element and N-parasitic radiating elements. The radiation pattern is electronically controlled by means of the variable devices loading the parasitic elements. These imply the achievement of low power antenna system with low fabrication cost. The ESPAR antenna can be designed to cover the frequency bands of the wireless local area network (WLAN), which are 2.4GHz and 5.8GHz. The modification can be achieved by loading the antenna elements with lumped circuits and a matching network system. This will be done by using the genetic algorithm optimisation technique.
