This article is dedicated to the design of rectifying antenna for wireless energy transfer at 2.45 GHz in the special case of low input power (typically <−10 dBm). As the rectifiers present an important non-linear behavior with such power levels, specific design guidelines must be respected in order to optimize the structure. Different rectifying circuits have been studied and their performances...
Electromagnetic wireless resonant energy links (WRELs) can be realized by using resonant coils coupled via their magnetic fields. By means of a simple equivalent network we investigate the efficiency of WRELs. It is demonstrated that, in order to improve the efficiency, a matching network at the input and output section should be used. In our arrangement the matching network is made by placing the...
