Characteristic Modes Analysis for the Design of a Wideband Circularly Polarized X-band Antenna
Characteristic Mode Analysis (CMA) is exploited for the design of a metasurface (MS) able to convert a linearly polarized field into a circularly polarized one. A MS is adopted for the design of an antenna aiming to operate in the whole X-band for satellite communications (7.25 GHz-7.75 GHz, 7.9 GHz-8.4 GHz). CMA results provide useful insight for properly tuning the unit cell of the finite MS, which is based on a loop element. A comparison between two different solutions is addressed and an excitation strategy for stimulating the desired characteristic modes is envisioned.
