| Summary: | A dual-band multifunctional polarization converting metasurface (PCMS) for linear-to-linear polarization conversion (LTLPC) and linear-to-circular polarization conversion (LTCPC) is presented in this paper. The PCMS converts LP incident waves into their orthogonal waves in dual frequency bands of 7.5–12 GHz with fractional bandwidth (FBW) of 46.15%, and 15.4–20.16 GHz with FBW of 26.77%, with a polarization conversion ratio (PCR) of 98%. Furthermore, the PCMS converts LP wave to circular polarized wave with axial ratio (AR), below 3 dB in the frequency range of 12–15.4 GHz with a FBW of 24.81%. To comprehend the designed MS operational principle the surface current distributions (SCD) are also discussed on numerous resonance frequencies. A prototype of the designed MS is fabricated, the simulated and measured results are in good agreement. The dual frequency bands and multifunctional PC characteristics of the MS make it useful for a wide range of microwave communication and radar systems. |
