A processor implemented method for setting antenna beam angle of metasurface beam steering antenna, the processor implemented method further comprising the steps of:

• receiving by a processor a command from a user interface, the command having an input angle value to tilt a position of a metasurface beam steering antenna, wherein the metasurface beam steering antenna is positioned horizontally in an XY plane further comprising a set of c-shaped copper patches with predefined dimensions to transmit and receive RF waves, and a varactor diode positioned between each pair of c-shaped copper patches acting as equivalent capacitors for an input reverse bias voltage, wherein the metasurface beam steering antenna comprises a repeating pattern of a plurality of unit cells, each unit cell of the plurality of unit cells are controlled independently to manipulate the transmitted and the received RF waves, wherein the metasurface beam steering antenna comprises two layers, wherein the top layer is an excitor and the bottom layer is a reflector;
• and mapping by using a processor, the input angle with a combination of c-shaped copper patches each comprising capacitor values, using a predefined lookup table for setting the antenna beam angle based on a reference voltage generated by the varactor diode, wherein to map the input angle with the combination of c-shaped copper patches, the one or more processors are configured to:
• select the capacitor values set to the c-shaped copper patch combination which has highest peak gain among the available c-shaped copper patch combinations to map the input angle based on a reverse bias voltage level of the varactor diode, wherein the c-shaped copper patches are separated from ground by a dielectric substrate, wherein each c-shaped copper patch combination may offer different capacitor values at the same frequency, wherein the different capacitor values are selected in adjacent unit cells of the metasurface beam steering antenna, wherein each unit cell size and spacing sub-wavelength being less than λ/2, wherein the predefined lookup table is iteratively updated with the selected capacitor values of the c-shaped copper patches combination, wherein the capacitor values set to the c-shaped copper patch combination are mapped with the input angle associated with the lookup table.
