Abstract

A circularly polarized broadband antenna is designed for Wi-Fi 7 applications. The patch antenna is modeled in the shape of G, and the feed position is adjusted to produce the arms with a length difference of λ/4. The G-shaped patch antenna has shown an impedance bandwidth of 5% (6.16−6.48 GHz) and a peak gain of 6.3 dBi. The metasurface is structured with a periodic array of 4 × 4 patches. The metasurface is sandwiched between dielectric substrates beneath the G-shaped patch. The outcome of these combinations has achieved an impedance bandwidth of 41% (4.85−7.37 GHz) and an axial ratio bandwidth of 26% (5.26−6.83 GHz), and the antenna achieved a peak gain of 7.45 dBic.
