The paper addresses a new approach to the integrated design of RF/Microwave receivers for power harvesting and conversion systems for ultra-low power densities. Such systems can be very useful in typical humanized environments in the presence of existing wireless systems with power densities as low as a few uW/cm2. Despite of the scarce RF power available, energy usable to extend battery life or to self-power low-duty cycle electronics may be scavenged by highly efficient receivers and power converter circuits designed in a unique design process. A multi-band antenna is used as the RF power receiver. Its rigorous frequency-dependent equivalent circuit in the presence of an incident field is used in the joint design of a rectifier stage and of a boost converter that can dynamically track the maximum pow-er point. This is obtained by a new simulation platform combining SPICE-like time-domain models of dispersive multiport components with the transient analysis of the control sub-system WE4A: RFID and Power Harvesting Technologies

The results of the analyses suggest that the UVGI technology delivers value for money. However, there are several limitations to this research including potential regression to the mean bias. Additional research is recommended using pre and post implementation data.
