© 2018 KIEES. A method to manipulate the main beam of patch antenna using non-uniform meta-surface (MS) is proposed in this paper. The proposed antenna is composed of a non-uniform MS placed directly atop of a patch antenna with an area of 100∗100 mm2 (0.82 λ 0∗ 0.82 λ 0), making it compact and low profile. After adding the MS to the patch antenna, the main-beam direction can be tilted by an angle of 30° from the boresight direction. The proposed antenna is studied and designed to operate around 2.45 GHz. Simulated results show that the antenna has an operating bandwidth from 2.372.51GHz and peak realized gain of 7.3dBi.
