To design and evaluate a low-profile, high-performance circularly polarized patch antenna using a metasurface for global 5G millimeter-wave communication systems.
Sandwiched a diagonally slotted patch antenna directly between a ground plane and a 4 × 4 symmetrical square ring metasurface without an air gap.
Excited surface waves along the metasurface to induce extra resonances, achieving an overall compact antenna volume of 1.1λ0 × 1.1λ0 × 0.093λ0.
Verified performance characteristics through millimeter-wave electromagnetic simulations and experimental hardware measurements.
Achieved an impedance bandwidth of 24.0 to 34.1 GHz (34.7% for |S11| < -10 dB) and a 3-dB axial ratio bandwidth of 24.1 to 29.5 GHz (20.1%).
Maintained a maximum gain of 11 dBic with low gain variation (9.5 to 11 dBic) and stable left-hand circular polarization spanning 24.2 to 29.5 GHz.
