Abstract: In this article, a single layer, ultrathin, multiband, and multifunctional reflective polarization converting metasurface (PCMS) is presented that can perform linear to linear (LTL) orthogonally with respect to the incident polarization, also called cross polarization conversion (CPC), and linear to circular (LTC) polarization conversion (PC). It consists of a periodic arrangement of an inclined H-shaped metallic patch, on the top of a F4B grounded dielectric substrate. The proposed configuration converts linear polarization (LP) to an orthogonal polarization in five frequency bands, i.e., 9-10.6, 15.9-16, 18.6-22.9, 23.7-23.8, and 25.9-26.9 GHz with more than 90% polarization conversion ratio (PCR). Furthermore, the proposed metasurface design accomplishes circular polarization (CP) in eight different frequency bands namely, 8.6-8.8, 10.9-11.4, 15.6-15.8, 16.8-17.7, 22.9-23, 23.3-23.4, 25.6-25.7, and 27.3-27.5 GHz, having the required axial ratio (AR$\le 3$dB). Multiple surface plasmonic resonances are the reason behind the different conversions. The experimental results are in good agreement with the simulated results. The ultrathin, simple structure, multiband, multifunctional characteristics, and compact size of the polarization converter make it an excellent option for 5G wireless systems, satellite communication, and stealth technologies.
