Abstract

An electrically-small Huygens rectenna is reported that operates at 915 MHz in the ISM band for wireless power transfer (WPT) applications. The rectenna consists of an electrically-small Huygens linearly-polarized (HLP) antenna and a rectifier circuit. The HLP antenna is developed by systematically combining two near-field parasitic resonant (NFPR) elements: an Egyptian axe dipole (EAD) and a capacitively loaded loop (CLL), together, with a small dipole antenna. The designed HLP antenna is electrically-small (ka < 0.89), low profile (0.0420), and produces cardioid-shaped directivity patterns with a very satisfactory peak realized gain value (4.4 dBi), wide half power beamwidth (136°), and high front-to-back ratio (26 dB). A rectifier circuit is designed and integrated with the HLP antenna to realize the rectenna. The rectifier consists of one HSMS286 Schottky diode and three lumped elements. The rectenna achieves a maximum RF to DC conversion efficiency: 86%, and a 2.4 V output DC voltage for a -5.0 dBm input power. Owing to its compact footprint and excellent radiation performance, this electrically-small rectenna is suitable for wirelessly powering sensors and unmanned aerial vehicles (UAVs).
