Title :
An experimental low power density rectenna
Abstract :
Describes the design and performance of a 2.45-GHz rectenna that absorbs small amounts (milliwatts) of microwave power at incident power density levels that are 10000 times lower than those normally used and then, after a microwave impedance step up of 50, converts it into DC power at useful voltage levels. Several applications are discussed, including a transponder in a communications or sensor system in which the interrogating transmitter also supplies power to the transponder.<>
