A study of deployable center-fed reflectarray antenna

Abstract

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 foldable sub-substrates, and a backfire antenna. This antenna can speedily be installed by attaching the backfire antenna and deploying the folded sub-substrates. The design results show that the antenna can satisfy the target gain by adjusting the deployment angle of the sub-substrates. In addition, the validity of the design is verified by measurements.
