Abstract

In this communication, a fully automatic measurement setup for the voltage distribution of a rectenna in space is reported. This 3D voltage pattern defines the variation of the DC voltage obtained by a rectenna as a function of the direction away from the transmitting antenna. It allows optimizing the placement of the rectenna in the zone of interest. A comparison is performed between the 3D voltage pattern of a 2.45 GHz rectenna and the radiation pattern of the receiving antenna. The results demonstrate that the influence of the rectifier on the radiating part cannot be ignored and validate the need of a 3D voltage distribution measurement to accurately characterize a rectenna system.
