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.
