A 2.45 GHz Shielded, Miniature Power and Data Receiver

Abstract

The design of a rectenna system for practical use is outlined in detail. The system is physically small ($24 \times 20 \times 3 mm^{3}$) and is shielded by a ground plane from electronics behind. First experimental results are shown, using Direct Antenna Modulation, for combining power and data transfer using an information bandwidth that is wider than the antenna bandwidth.
