摘要：

In this contribution, we report our recent findings in the design of transmissive static and reconfigurable phase-gradient metasurfaces for antenna applications. In particular, we show that transmissive metasurfaces can be efficiently used to manipulate the radiative characteristics of phased-arrays or single antennas, achieving an extension of the scan range or a dynamic transformation of the radiation pattern, respectively. For these purposes, we explore the design of both local- and non-local phase-gradient Huygens metasurfaces. Several realistic antenna configurations are proposed and checked with extensive full-wave simulations that confirm the huge potentialities of this design scheme for conceiving next-generation antenna systems characterized by enriched radiative capabilities, especially useful in beyond-5G and 6G wireless systems.
