摘要： An electromagnetic shield 10a includes a plate-shaped base 5. The base 5 has a first surface 11 and a second surface 12. The first surface 11 is a surface configured to allow an electromagnetic wave to be incident on the first surface 11. The second surface 12 is distant from the first surface 11 and extends along the first surface 11. The electromagnetic shield 10a includes a dielectric. The first surface 11 includes a plurality of first recessed portions 11a and a first solid portion 11b. The plurality of first recessed portions 11a are arranged at a given interval in a particular direction along the first surface 11. The first solid portion 11b includes a surface 11s in contact with an edge 11c of the first recessed portion 11a in the particular direction, the surface 11s being a basis of a depth of the first recessed portion 11a. The first solid portion 11b has a dimension in a depth direction of the first recessed portion 11a, the dimension being equal to or greater than a depth D1 of the first recessed portion 11a. The second surface 12 includes a plurality of second recessed portions 12a arranged alternately with the plurality of first recessed portions 11a in the particular direction.

摘要： This disclosure relates generally to metasurface beam steering antenna and method of setting antenna beam angle. Conventional approaches perform electronically beam steering using phase array which requires bandwidth with higher data rates. The present disclosure enables metasurface antennas tilt antenna beam in a given direction, where the varactor diodes are operated in reverse bias so that different values of capacitors combination lead to electronic beam scanning. The processor of the metasurface beam steering antenna receives a command having an input angle to tilt the angle beam position. The processor processes the command by mapping the input angle with the set of c-shaped copper patch combination having the capacitor values using a predefined lookup table for setting the antenna beam angle based on a reference voltage generated by the varactor diode. The lookup table is iteratively updated with the capacitor values of the c-shaped copper patches.
