Nasimuddin, Qing, X. A metasurface-based stacked patch antenna for wideband circularly-polarized radiation. 2021 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (APS/URSI)
Abstract:
A metasurface-based stacked antenna is proposed
for wideband circularly polarized (CP) applications. The proposed
antenna consists of a metasurface, a patch radiator, a stacked
patch, and a coaxial feed along the diagonal line. The antenna
prototype is with 2-VSWR bandwidth (2-VSWRBW) of 30.9%
(3.28 GHz – 4.48 GHz), 3-dB axial ratio bandwidth (3dB-ARBW)
of 17.5% (3.65 GHz – 4.35 GHz), and gain greater than 7.25 dBic
across the 3dB-ARBW with maximum gain of 8.25 dBic at 4.0
GHz.
