Development of Scanning Spot Beam Reflectarray Antenna

Abstract

Conventional multispot beams and multiscanning beams have been developed using a single reflector by combining the characteristics of reflectarray antennas, which change the beam direction, depending on the frequency and polarization. In this study, we developed a design method and obtained measurement results of a scanning spot beam reflectarray antenna whose beam direction is changed by the frequency in the elevation direction and polarization in the azimuth direction.
