Abstract
The performance and efficiency of three planar rectennas, designed on three different PCB materials, have been evaluated at 2.45 GHz. A maximum RF-to- do conversion circuit efficiency of 55% was achieved. An output do voltage of 1 V was measured over a distance of 1 m from a rectenna having 7 dB ante nna gain.
