Abstract :
This paper presents design and performance analysis of various element shapes for microstrip reflectarray formed of patches of variable size. The comparison focuses on effect of the elements boundaries on the performance represented by the range and slope of the reflection phase response. Variation of the response with frequency is also investigated to assess the frequency response of the proposed elements. Various shapes in the form of patches and double-rings inspired by the Koch fractal are investigated. The analyses were performed using the CST Microwave Studio software Package.
