Description
Summary:This paper presents design and performance analysis of some novel aperture shapes for microstrip reflectarray using patches of variable size. A comparison has been carried out between performance of these novel aperture shapes and some traditional aperture shapes of microstrip reflectarray. For this comparison, first a 29 × 29 center-fed broadside reflectarray is designed and fabricated. Close agreement between simulated and measured radiation patterns confirms the validity of design process. Based on this confirmed design process, reflectarray with different aperture shapes namely reflectarray with diamond-shaped aperture and reflectarray with octagonal aperture has been designed and simulated. From simulated radiation patterns, performance of these reflectarrays has been evaluated and presented.
