The method will be validated with a metallic ring on a dielectric substrate.

Circularly polarized wave beamforming using one‐dimensional Fresnel zone plate

“…The unit cell of the circular polarization converter is designed using full‐wave commercial solver ANSYS HFSS under an infinite periodic boundary condition. Equivalent circuit analysis is conducted based on transmission line theory . The aforementioned four‐layer circular polarization converter is fabricated on a Taconic TLY substrate (ε r = 2.20, h = 0.128 mm, t = 0.017 mm).…”
