Resumen/Abstract
This paper presents a new computer aided technique to automatically design reflectarray antennas. The characteristics of the reflecting elements are selected considering the spatial phase delay at each unit cell to achieve a progressive phase shift. The reported technique is able to generate the geometrical model of the reflectarray antenna taking into account some input parameters such as the unit cell type, the operating frequency, the focal length, the periodicity and the desired main beam radiating direction. The tool also computes and provides the phase curve of the unit cell. To evaluate the performance of the new method, a reflectarray has been designed. Excellent results in terms of gain and polarization purity have been achieved.
