A novel microwave rectifier based on Schottky diodes
which applies power divider and diodes array to maintain high rectifying efficiency and large power capacitance
is presented.The proposed structure flexibly reaches different power capacitance requirements with a variation of the branch number of the power divider.The rectifier is compact
simple and high efficient.The microwave rectifying efficiency is higher than 60% when the input microwave power is between 36dBm to 42dBm at 2.45GHz.The highest microwave rectifying efficiency reaches 68% at 41dBm input microwave power.The maximum power capacitance achieves 43dBm.
