Ultra-broadband Linear Polarization Converter Based on Single-layer Reflective Metasurface

In this paper, an ultra-broadband polarization converter based on single-layer reflective metasurface is proposed. The simulation results show that the polarization conversion ratio (PCR) is higher than 90% in the frequency range of 12.04 to 32.44GHz. Compared with the conventional polarization converter, the polarization converter presented in this paper has more advantages in terms of bandwidth and electrical dimension, and has great practicability and wide application prospect in the communication field.
