Abstract :
A new rectenna with a loop antenna and a designed rectifier by commercial Schottky diode has been developed. The used doubler rectifier provides optimum output DC voltage of 1.54 V as well as 47 % RF-DC conversion efficiency is achieved when 0 dBm RF power is received at 925 MHz. The rectifier has good impedance matching with the loop antenna corresponding to its optimum frequency response.
