Design of Deployable Center-Fed Reflectarray Antenna

In this paper a deployable center-fed reflectarray antenna for mobile satellite communication systems is proposed. The proposed antenna consists of a main-substrate, four sub-substrates, and a backfire antenna. It can be easily installed by attaching the backfire antenna and deploying the folded sub-substrates. In this study, the proposed antenna is designed, and its characteristics are analyzed. The results show that the antenna can satisfy a target gain by adjusting the deployment angle of the sub-substrates.
