Abstract

This paper presents the polarization reconfigurable circular patch antenna. The reconfigurability feature is realized through the alteration of the feeding network. The antenna consists of a circular patch as a radiator, and orthogonally fed by a co-planar waveguide (CPW) slotline which terminated with tapered transformer. The CPW slotline are interconnected with quarter wavelength phase delay slotline. Eight switches are placed at the CPW transmission slotline, to either activate or deactivate the phase delay slotline. Consequently, depending on the switch configurations, the polarization can be altered to the desired sense, either linear, right-hand circular or left-hand circular polarization.
