Some Discussions on Broadband Circularly Polarized Patch Antennas Using Metasurface Structure

Abstract

It has been well-known recently that Metasurface (MS) can generate circular polarization (CP) covering a wideband. In this talk, the author would talk about recent progress on wideband CP antenna using MS. Furthermore, for consideration of the limited area, the effect of edges of some MS will be discussed.
