Abstract :
In this paper, a multi-band polarization converter using anisotropic metaurface is proposed. The unite cell of the anisotropic metaurface is mediated by electric-field-coupled (ELC) resonator. The proposed metasurface can converts the linearly polarized waves to its cross polarization at 7.83GHz and 10.22GHz. What´s more, the designed metasurface can convert the linearly polarized waves to left handed circularly polarized waves at 7.76GHz and 10.54GHz, and convert the linearly polarized waves to right handed circularly polarized waves at 7.91GHz and 9.94GHz. The polarization conversion ratio (PCR) at 7.83GHz and 10.22GHz are more than 96%. The axial ratio at 7.76GHz, 7.91GHz, 9.94GHz and 10.54GHz are smaller than 1dB.
