A high gain wideband circularly polarized antenna with asymmetric metasurface
An asymmetric-metasurface based wideband circularly polarized (CP) microstrip antenna using a coaxial probe is proposed for L-band applications. The antenna involves a stacked asymmetric-metasurface, a radiating rectangular-patch and a coaxial feed. An asymmetric-metasurface is designed using rectan...

| description | An asymmetric-metasurface based wideband circularly polarized (CP) microstrip antenna using a coaxial probe is proposed for L-band applications. The antenna involves a stacked asymmetric-metasurface, a radiating rectangular-patch and a coaxial feed. An asymmetric-metasurface is designed using rectangular unit cells and smaller size unit cells along one of the diagonal lines. The asymmetric-metasurface is placed above a radiating rectangular-patch with support of foam layer to achieve a wideband CP radiation. The measured performance of the prototype antenna achieves an impedance bandwidth (−10 dB return loss bandwidth) of 15.7% (1.58-1.85 GHz) with CP bandwidth (3-dB axial ratio) of 13% (1.58-1.80 GHz) and gain of ≥9 dBic. |
