Abstract: Phased array antenna’s radiation pattern can be electronically controlled, which makes them relevant solution for multipath interference. Electronically Steerable Parasitic Array Radiator (ESPAR) antenna systems are part of the family of phased array antenna under the umbrella of aerial beam-forming antennas. Generally ESPAR antenna system design considers the quarter wavelength approach. In practice there is a significant number of multiband systems with many applications integrated in one single device. In this study the focus is on the modification of the antenna designs for dual-band functionality which is limited on the ESPAR antenna’s structural parameter. This modification should result in an antenna system which operates in both 2.4GHz and 5.8 GHz bands of the IEEE 802.11 WLAN (Wireless Local Area Network) suitable for rural areas. The approach employed in this work consists of different stages of structural modification with careful optimization processes. There two adopted process are the quarter wavelength design and the optimization process, conducted through the genetic algorithm.
