Abstract

Bu çalışmada, yeni bir çapraz kutupsal metayüzey (CPM) sunulmuştur. Metayüzey, CST mikrodalga stüdyosu kullanılarak Roger 5880 alt tabakası üzerinde tasarlanmıştır. Metayüzey tasarımı, U şeklini içeren bölünmüş bir halka içerir. Bu metayüzey, K ve Ka frekans bantlarında x/y kutupsal bir doğrusal dalgayı y/x kutupsal doğrusal bir dalgaya dönüştürebilir. 12.15 GHz geniş bantta (11.95-12.6, 23.5-35 GHz) %90 kutupsal dönüşüm oranına (PCR) sahiptir. Bu tasarım ayrıca 30 dereceye kadar açısal kararlılığa sahiptir. Bu çalışma, bazı K- ve Ka-bant uygulama çalışmalarında kullanışlıdır.

A CROSS-POLARIZER METASURFACE DESIGN FOR K- AND KA-BAND APPLICATION STUDIES

Abstract

In this study, a novel cross-polarizer metasurface (CPM) is presented. The metasurface is designed on Roger 5880 substrate by using CST microwave studio. The metasurface design features a split ring that incorporates a U-shape. This metasurface can convert an x/y-polarized linear incident wave into a y/x-polarized linear wavein K- and Ka- frequency bands. It has a 90% polarization conversion ratio (PCR) in the 12.15 GHz broadband (11.95-12.6, 23.5-35 GHz). This design also has angular stability up to 30 degrees. This study comes in handy with some K- and K-band application studies
