Abstract

We propose an electronically steerable parasitic array radiator antenna that is about 96% smaller than a conventional one. The antenna can shape a beam with a working gain of about 6 dBi without a matching circuit and steer the beam in steps of 45°. The reactance with which parasitic elements are loaded is designed to achieve vswr of <3 in the frequency band for IEEE802.11b by controlling the set of reactance values in three steps. Consequently, a pen-sized beam steerable antenna can be made for a 2.4-GHz-band wireless local area network. The antenna is unique in that the current excited on parasitic elements is stronger than that excited on the fed element when a beam is shaped.
