The unit cell of the metasurface is composed of S- and G-shaped patches separated with a parasitic gap and the grounded via is connected to the full ground plane. The unit cell is etched on an FR4 substrate (dielectric constant, \u03b5r = 4.4, loss tangent, tan \u03b4 = 0.02), with compact dimensions of 10 mm3 \u00d7 10 mm3 \u00d7 1.6 mm3. This structure provides a resonance at 5.2 (ISM), 6.9, and 8.05 GHz (X-band) frequencies. The designed unit cell structure is studied for Transverse Electric (TE)\/Transverse Magnetic (TM) incident waves and their responses to the various incident angles. The corresponding PCR is calculated, which shows 92% in the lower frequency band (5.2 GHz), 93% in the second frequency band (6.9 GHz), and 94% in the high-frequency band (8.05 GHz). The total efficiency of the structure shows 83.2%, 62.95%, and 64.6% at the respective resonance bands. A prototype of the proposed PCRM with 3 \u00d7 3 unit cells is fabricated to validate the simulated results. The experimental data agrees with the simulation results. The compactness, triple-band operation with a high PCR value of more than 92% makes use of the designed metasurface in wireless antenna-integrated applications at ISM and X-bands.<\/jats:p>","DOI":"10.3390\/s22218213","type":"journal-article","created":{"date-parts":[[2022,10,26]],"date-time":"2022-10-26T09:59:37Z","timestamp":1666778377000},"page":"8213","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["A Triple-Band Reflective Polarization Conversion Metasurface with High Polarization Conversion Ratio for Ism and X-Band Applications"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7248-3406","authenticated-orcid":false,"given":"Badisa Anil","family":"Babu","sequence":"first","affiliation":[{"name":"Department of Electronics and Communication Engineering, GMR Institute of Technology, Razam 532127, India"},{"name":"Antennas & Liquid Crystals Research Centre, Koneru Lakshmaiah Education Foundation, Vaddeswaram 522302, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6893-6978","authenticated-orcid":false,"given":"Boddapati Taraka Phani","family":"Madhav","sequence":"additional","affiliation":[{"name":"Antennas & Liquid Crystals Research Centre, Koneru Lakshmaiah Education Foundation, Vaddeswaram 522302, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4555-7438","authenticated-orcid":false,"given":"Sudipta","family":"Das","sequence":"additional","affiliation":[{"name":"Department of Electronics & Communication Engineering, IMPS College of Engineering and Technology, Malda 732103, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9730-4622","authenticated-orcid":false,"given":"Niamat","family":"Hussain","sequence":"additional","affiliation":[{"name":"Department of Smart Device Engineering, Sejong University, Seoul 05006, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1745-0270","authenticated-orcid":false,"given":"Syed Samser","family":"Ali","sequence":"additional","affiliation":[{"name":"Department of Electronics & Communication Engineering, University Institute of Technology, Burdwan 713104, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8109-2055","authenticated-orcid":false,"given":"Nam","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Information and Communication Engineering, Chungbuk National University, Cheongju 28644, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Bukhari, S.S., Vardaxoglou, J., and Whittow, W.
