Abstract

This paper addresses different cases of radio frequency harvesting using different antenna types as transmitting antenna but using just the lead of the capacitor as the wire antenna at the receiving end with a voltage rectifier circuit. Different antennas were used in the input and with two different rectification circuits the conversion efficiencies were studied accordingly. For a source of log periodic antenna, without any antenna, 27.31% RF-DC power conversion efficiency value was obtained at the far-field. For a source of half wavelength dipole antenna, at the near-field, 50.53% RF-DC power conversion efficiency value was obtained. For a source of helical antenna, up to 5 cm distance about 14.78% RF-DC power conversion efficiency was observed. For the Yagi-Uda antenna used as a source, RF-DC power conversion efficiency that was obtained at the far was 28.89% without any receiving antenna..
