If metasurface kept as a substrate or Superstrate to an antenna what are the differences what are the difference between the advantages and disadvantages between them
@Md.Abdul kaium Khan. Sir I can understand that keeping the metasurface will enhance the properties of the antenna. My question was what is difference between them keeping as a substrate or superstate.

In the general case, the metasurface as superstrate work as Frequency Selective Surface and Polarisation Filter. On the other hand, the Superstrate metasurface can increase Gain of printed antenna.
The substrate metasurface work only as substrate with specific permitivity and permeability.
