N2 - A new beam-steering method is proposed for a broadside patch radiator, radiating under a metasurface (MSF) for enhanced gain. A 3D-printed structure that hosts 20 fluidic channels in a 5×4 array is added beneath the MSF. By selectively filling-in the channels with distilled water, a high ϵrcontrolled-shape block is formed re-directing the main lobe direction. The presented structure consists of a 4.8 GHz patch radiator with 6 dBi of gain. The addition of a 10×10 cells MSF enhances the broadside lobe gain to approximately 14 dBi, and the use of selectively filled fluidic channels can cause 33° of beam tilting in two directions. The gain of the tilted beams remain higher than 10 dBi in both directions.
