New Scanning-Spot Beam Reflectarray Antenna Design

Abstract

In this report, a new design for a reflectarray antenna using mirror configuration will be proposed. By adapting to the two characteristics of a reflectarray antenna that changes beam directions using frequency and polarization, it is possible to realize a multi-scanning beam whose performance is as good as a conventional multi-spot beam with one reflecting mirror. Herein, we examine a scanning-spot beam that changes the beam direction by using frequency in the elevation direction and polarization in the azimuth direction in the Ka band. As a result, the proposed design efficiently covered the desired service area.
