  • Abstract
    This paper presents experimental results on several self-complementary bow-tie antenna arrays populated with rectifier diodes. Results with two different diodes are compared, and the number of diodes, antenna polarization, DC load, DC connection (parallel/series) and incident power density are varied. The transmitter is in the far field and the incident power density ranges from 10 to 125μW/cm2 at 2.3GHz. The main conclusion of this work is that it is possible to transmit useful power wirelessly, using low and safe power density levels (tens of μW/cm2), and receive it with a scalable device.
