Abstract

An electrically small rectenna was designed and tested at the global positioning system (GPS) L1 frequency (1.5754 GHz). The metamaterial-inspired near-field resonant parasitic antenna size (ka ∼ 0.467) and its direct match to the input impedance of the rectifying circuit decreased the whole size of the rectenna (ka ∼ 0.611). The simulated and measured rectifying efficiencies were, respectively, 75.7 and 79.6% when the input power to the rectifying circuit was 0.0 dBm (1 mW). The highest rectifying efficiency, 84.7%, was achieved at the GPS L1 frequency for a 3.0 dBm input power. The simulated and measured results are in good agreement.
