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‐dc conversion circuit efficiency of 55% was achieved. An output dc voltage of 1 V was measured over a distance of 1 m from a rectenna having 7 dB antenna gain. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 31: 86–91, 2001.
