Design of a Folded Reconfigurable Reflectarray Antenna for Mono-Pulse Radar Application

Abstract

A folded reconfigurable reflectarray antenna for mono-pulse radar application is presented in this paper. The proposed antenna combines the properties of reconfigurable reflect-array antenna and folded reflectarray antenna. A reconfigurable reflectarray with $15\times 15$ elements is developed to verify the design method. The antenna design is calculated and simulated using MATLAB and HFSS, and detailed results are presented and discussed. The reconfigurable reflectarray antenna can operate at Ku-band and provide the performance of beam scanning. This reconfigurable reflectarray antenna has significant potential for satellite applications, due to its low profile, simple control and beam-scanning capability.
