Several electrically small, metamaterial-inspired near field resonant parasitic (NFRP) antennas are designed for operation at the GPS L1 frequency (1.5754 GHz). Their intended use is in a rectenna system. All these antennas are based on the electric coupling between the NFRP element and the driven monopole element. They are designed to be matched to a 50Ω source. The simulated results of the magnitude...
A GPS L1 (1.5754 GHz) rectenna has been developed for low input power. The rectenna incorporates a high efficiency, electrically small, metamaterial-inspired near field resonant parasitic antenna, and a Schottky diode that has a low built-in voltage, and a resistor as the load. The measurement results show that the overall efficiency of the rectenna with the resistive load is 34.8% and the voltage...
A 1.575 GHz rectenna has been developed for low input power operation. The rectenna incorporates a high efficiency, electrically small, metamaterial-inspired near field resonant parasitic antenna, and a Schottky diode that has a low built-in voltage, and a resistor as the load. The rectenna was analyzed with the Harmonic Balance method provided by the Advanced Design System (ADS). The measurement...
An electrically small, metamaterial-inspired near field resonant parasitic (NFRP) planar protractor antenna is designed for operation, as a proof-of-concept choice, at the GPS L1 frequency (1.5754 GHz). It is based on electric coupling between a capacitively loaded loop (CLL) NFRP element and a driven monopole. Modified versions are then integrated with simplified rectifying circuits to realize two...
