This paper addresses recent results obtained in the Ku band by using an innovative cross dipoles rectenna topology. The targeted application is the harvesting of the spill-over losses of microwave antennas for powering autonomous wireless sensors used for satellite health monitoring. The experimental results demonstrate that this compact antenna can provide at least 1 mW of DC power when it is illuminated by an incident electric field of 38 V/m or higher.
