It has been demonstrated to achieve the LP-to-CP conversion at two separate frequency bands, including 11.52-11.84GHz and 19.83-20.01GHz. The circular polarization type is specified as a right-hand circular polarization (RHCP) for the first band and a left-hand circular polarization (LHCP) for the second band. In both of frequency bands, the metasurface structure reveals highly efficient features. Besides that, the metasurface structure exhibits highly efficient features within 3-dB bandwidths of 10.29-12.58GHz and 19.32-20.50GHz. Crucial parameters of polarization conversion such as ellipticity, axial ratio, andinfo:eu-repo/semantics/openAccessArticle143Iğdır Üniversitesi, Mühendislik Fakültesi, Elektrik Elektronik Mühendisliği Bölümü, Iğdır, Türkiye,Bayburt Üniversitesi, Teknik Bilimler Meslek Yüksekokulu, Elektrik ve Enerji Dairesi Başkanlığı, Bayburt, Türkiye,Iğdır Üniversitesi, Mühendislik Fakültesi, Elektrik Elektronik Mühendisliği Bölümü, Iğdır, Türkiyeİngilizce10.21597/jist.13990681260628
