Abstract :
A new concept for solid state wireless microwave power transmission is presented. A 2.45 GHz rectenna element that was designed for over 85% RF to DC power conversion efficiency has been used to oscillate at 3.3 GHz with an approximate 1% DC to RF conversion efficiency. The RF radiation was obtained from the same circuit by supplying the DC output with reverse polarity DC power.
