N2 - A novel ultra-wideband metasurface antenna with dual-circular polarization is proposed in this paper. The high, low, and medium circular polarization (CP) mode frequencies of the antenna are generated through the radiation metamaterial patch, the 3/4 ring feed network, and the coupling between them, respectively. The characteristic modes of low and mid frequency exhibit a broad frequency coverage, ensuring that the antenna's entire operating band is continuous and broadband. The antenna is fed by a low dispersion annular microstrip cross slot coupling network with broadband approximate 90° phase difference. The dimensions of the proposed antenna are 0.73λ × 0.73λ × 0.066λ. The overlap impedance bandwidths in simulations and measurements are 81.01% of left handed circular polarization (LHCP, 3.54-8.36GHz) and 81.92% of right handed circular polarization (RHCP, 3.51-8.38GHz). The overlap axial ratio bandwidth (ARBW) is 64.74% (LHCP, 3.52-6.89GHz) and 62.97% (RHCP, 3.58-6.87GHz), respectively. This broad AR bandwidth is sufficient to cover uplink and downlink transmission frequencies of C-band satellite communications.
