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

A reflectarray antenna adapts to the reflection phase control function of a metal plate loaded frequency selective reflector. If the shape and the arrangement of the elements are devised, it is possible to control the reflection phase of V and H pola

Recent studies have proposed a multi-beam system that requires fewer mirror surfaces. This is made possible by sharing V and H polarized waves, which is one of the unique properties of a reflectarray antenna, in a single mirror surface. In this study

This paper proposes a method of equivalent circuit design. A technique was examined for formulating an equivalent circuit model of a meander line polarizer, and calculating electrical characteristics without using numerical analysis. Also, precision

The analysis of the reflectarray antenna's frequency characteristics is a time consuming task. This is owing to the design of the size of the phasing elements, and the analysis of the reflection phase of the phasing elements. We propose a method for
