A radio frequency (RF) energy harvesting device comprises a scalable metamaterial resonator antenna and a rectifying circuit formed on a flexible plastic substrate. The metamaterial resonator antenna comprises a metal (for example, silver) structure so that the metamaterial antenna is fixedly disposed (i.e., printed or deposited/etched) on the flexible substrate and configured to resonate at RF frequencies by using primary and secondary antenna segments connected by linking segments such that captured RF signals are generated at two antenna end points that are 180° out-of-phase with each other. The rectifying circuit includes additional metal structures that are also printed or otherwise formed on the flexible substrate, and one or more circuit elements that are configured to pass positive voltage pulses from the captured RF signals to an output node. A variety of metamaterial resonator antenna configurations are provided. |
