In this paper, a novel reconfigurable metasurface (NRM) with coincident and ultra-wideband linear-to-linear (LTL) and linear-to-circular (LTC) polarization conversion functions is proposed. The unit of the proposed NRM consists of superstrate, air layer, metal patch, substrate and metal ground successively. By loading micro-electromechanical system (MEMS) between two adjacent metallic via, the proposed NRM can realize LTL and LTC polarization conversion efficiently. Numerical simulation results
more » ... simulation results reveal that the bandwidth of LTL and LTC polarization conversion are coincident from 5.7 GHz to 23.5 GHz (fractional bandwidth of 122%). It is worth mentioning that few metasurface in existing literature can achieve highly coincident and ultra-wideband LTL and LTC polarization conversion functions. Finally, measurement results are in accordance with simulation results.
