Experimental study demonstrates broadband circular polarization in a single-layer metasurface antenna, highlighting a simplified low-profile architecture for wireless devices.

Key Points

To develop a low-profile, single-layer circularly polarized metasurface antenna with wideband performance using characteristic-mode analysis.
Applied characteristic-mode analysis to evaluate the resonant modes and current distributions of a 3×4 metasurface.
Introduced a rotated coplanar waveguide feeding line to excite orthogonal e-TM30 and e-TM04 modes with a near 90° phase difference on a single layer.
Fabricated and measured a prototype antenna with a low-profile thickness of 0.058λ₀.
Achieved an impedance bandwidth of 25% covering 4.870 to 6.26 GHz.
Demonstrated a 3-dB axial ratio bandwidth of 19.42% spanning 5.30 to 6.44 GHz, with a peak broadside gain of 8 dBi.
