Efficient design of rectifying antennas for low power detection

Summary form only given, as follows. This article is dedicated to the design of rectifying antenna for wireless energy transfer at 2.45 GHz and low input power (−10 dBm). Specific design guidelines must be respected to optimize the structure. Different rectifying circuits have been studied and their performances have been evaluated. The effects of the antenna impedance have been investigated to improve the performances. Two test-circuits have been manufactured and measured to validate the interest of a global design approach.
