Abstract

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 across the resistor is 0.73 V at the GPS L1 frequency, 1.5754 GHz, when the power delivered to the antenna is 1.0 mW (0.0 dBm). Moreover, the maximum overall efficiency is 51.0%, which was achieved at 1.45 GHz.
