Abstract
Examples described herein include systems and methods for multiband harvesting. An example system may include a single wideband antenna followed by several narrowband rectifier chains. Each rectifier chain may include a bandpass filter, a tuned impedance matching network, and a rectifier. The outputs of the rectifiers may be combined using a summation network. The summation network, which may be a diode summation network, may in some examples provide good performance even when only a subset of the narrowband harvesters (e.g. a subset of the rectifier chains) is excited.
