摘要

This research paper presents the design and performance evaluation of a high-gain, wide-band circularly polarized antenna. The antenna structure consists of six layers, including a ground plane, substrate, driven patch, air gap, superstrate, and metasurface (MS). The substrate and superstrate are separated by an air gap, with the driven patch located on the upper surface of the substrate and the MS layer positioned on the upper surface of the superstrate. In order to achieve right-hand circular polarization (RHCP), the corners of the driven patch are truncated. The integration of the MS and air gap significantly contributes to the enhanced antenna performance. The antenna is fed by a coaxial cable, and it operates within a frequency range of 2.85–5.45 GHz, attaining a peak gain of 8 dBiC at 3.5 GHz. The axial ratio bandwidth covers a range of 3.2–4.4 GHz. The overall dimensions of the antenna are 0.7λ × 0.7λ × 0.09λ. The proposed antenna design demonstrates promising characteristics suitable for sub 6 GHz wireless communication applications.
