Abstract :
A new Near-Field focusing antenna based on a transmitarray lens working at 10GHz is presented in this contribution. Besides, a simple model for analyzing the Near-Field of a transmitarray based on array-based calculations, in which the spillover field is taken into account for more accurate results, is presented. The model is validated by comparing its results and the ones obtained in a full-wave simulation of the antenna with a commercial software and, also, the effect of the spillover is studied. Finally, several lens designs are presented and analyzed using the model presented in this contribution.
