This paper presents a pattern reconfigurableantenna with low-profile and wide bandwidth. Theantenna is composed of a patch layer, a metasurface(MS) layer, and a full ground plane. The radiation patchconsists of a microstrip-fed square and three parasiticpatches. The MS with 4×4 units is added on the topof the patch layer to improve bandwidth as well as tuneradiation pattern. Ten of the MS units are available toconnect with the ground plane, each of which is loadedwith a PIN diode to control the shorting state, providing12 beam states with reconfigurable beams between±5◦ to ±15◦ both in xoz and yoz planes. The proposedantenna has been fabricated and measured. Measurementshows that the antenna has a wide impedance bandwidthof 4.02-5.72 GHz, a beam scanning range of -16◦-15◦ inxoz plane and -13◦-15◦ in yoz plane, peak gain range of4.94-6 dBi. With a planar shape of low profile and fullground plane, the antenna design is a good candidate tobe applied in wireless communication systems with conductivesurface.
