Abstract

This study focuses on the design and analysis of Ku band reflectarray antenna using a novel crossed dumbbell (clover) patch unit cell. The reflectarray is proposed for application in satellite communication more specifically for Satellite newsgathering (12.5-13.75 GHz). The clover shaped unit cell is designed for 13.07 GHz and the suitability of the unit cell is validated using the phase characteristics analysis. The effect of the elements on the performance represented by the range of the reflection phase is of prime importance. From the observation, Clover unit cell has large phase variation compared to minkowski and koch unit cells. Therefore, the main purpose of this study is to investigate and validate the novel unit cell with a wide phase characteristics and the reflectarray constructed.
