Abstract
Bu çalışma, 10 GHz için iki mikroşerit yansıtıcı dizi tasarımı sunmaktadır. İstenen yönde yansıtma elde etmek için her iki yansıtıcı yüzeyde değişken boyutlu birim hücreler kullanılmıştır. Yüzeylerden birinde, çokgen biçimli mikroşerit yama ve 3 katmanlı birim hücre, diğerinde kare çevrim biçimli yama ve tek katmanlı yapı kullanılmıştır. Her iki dizi de 10 GHz'de 10λ × 10λ boyutunda olup, gelen dalgayı θ = 30° yönünde yüksek kazançlı kalem ışın olarak yansıtmaktadır. 10 GHz'deki kazanç, 3-katmanlı yapı için 23,6 dB ve tek katmanlı yapı için 26,1 dB'dir. Çok katmanlı yapı ile daha geniş kazanç-bant genişliği elde edilmiştir; 3-dB kazanç bant genişliği 3- katmanlı yapı için yaklaşık %22 iken tek katmanlı yapı için yalnızca %12 olarak bulunmuştur.

Abstract
This paper presents two microstrip reflectarray designs based on variable size unit cells for 10 GHz. One design uses a 3-layer unit cell with polygon shaped patch and the other uses a unit cell with 1-layer square loop patch. Both arrays have a size of 10λ × 10λ at 10 GHz, can reflect the incoming wave as a high gain pencil beam in the desired direction of θ = 30°. Gains at 10 GHz are 23.6 dB and 26.1 dB for the 3-layer and one-layer structures, respectively. The multi-layer structure resulted in a wider gain banwdith. Simulation results show that the 3-dB gain bandwdith is about 22% for the 3-layer structure reflectarray, as compared to 12% for the one-layer structure
