Abstract
This paper presents a linearly polarized Yagi-Uda patch antenna deployed with rectangular parasitic elements. In this work, the effect of shorting location or switching location towards the performance of beam tilt angle and reflection coefficient is investigated. By varying the shorting location, the direction of a main beam can be tilted to various angles. However, since the beam patterns overlap with each and other, only four shorting locations are proposed to achieve three sets of directive beam patterns which have maximum separation between them. The antenna is capable to steer the main beam to three different directions at theta of +30°, 0° and -30° at H-plane while sustaining a constant reflection coefficient bandwidth of 274 MHz around center frequency of 5.8 GHz. Operating around 5.8 GHz frequency, this antenna is capable to be used for WIFI and WIMAX applications.
