Holst Centre and imec have identified all the subsystems that make up a far-field RF energy transport system. Such a system may be used to (re)charge the batteries of wireless sensors that are used in smart building integration applications. By optimizing both the transmitter radiation pattern and the receiving rectifying antenna, the RF energy transport efficiency can be greatly improved. In particular, it will allow a significant increase of the operating distance between the RF source and the...
