Abstract :
In design of a reflectarray antenna, we considered the incident angle and the polarization on the refectarray surface. In the result, the reflection phases can be controlled only by varying the radius of ring elements, and it was found that the thickness of a dielectric substrate had an optimal value that minimizes the phase errors. To verify the design method, we manufactured and measured a circularly polarized reflectarray antenna for satellite broadcasting reception.
