Most of the implementations of modulated metasurface (MTS) antennas consist of planar
circular apertures made of sub‐wavelength patches (or slots) printed (or etched) on a …

Metasurfaces (MTSs), the 2D equivalent of metamaterials, are thin artificial layers
characterized by unusual reflection and transmission properties of plane waves and/or …

In this paper, a new method to design multi-beam antenna based on parasitic patch and
shorting-pin is proposed and demonstrated through two cases of singleand multi-source. For …

The evaluation of the radiated field is a standard requirement in antenna development to
assess the radiation performances. However, this characterization process is costly and …
