Though polarization-conversion (PC) metasurfaces have been thoroughly explored in the microwave and optical regimes, they have seldom been used in everyday applications, such as improving the overall performance of antennas for wireless communication. This study not only focuses on the strategy for designing an efficient PC metasurface, but also applies it to construct a high-performance Cassegrain antenna. This metasurface is capable of simultaneous polarization manipulation and arbitrary phase tailoring, while the antenna has the advantages of low profile, high directivity, broad bandwidth, and high polarization purity.
