A novel wideband partially reflective surface (PRS) for printed antennas gain enhancement is proposed in this paper. The proposed PRS is constructed by two layers separated by an air-gap. It is composed by an inductive patch with a star flower-shaped aperture etched on the bottom faces of its two layers and a capacitive star flower-shaped patch that is placed on the top face of its upper layer. The presented PRS with a broadband operation extending from 7.76 GHz to 11.16 GHz is proposed to improve the gain of printed antennas operating around this band. The usefulness of the proposed PRS is examined by placing an array of 8 ( 9 over a single-layer printed feeding antenna (FA). The gain of the considered FA is considerably enhanced after the implementation of the PRS. Hence, the usefulness of the designed PRS is demonstrated for enhancing the gain of printed antennas operating in X-band.
