Cross dipoles rectenna for microwave applications

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.
