Efficient 2.45 GHz Rectenna Design with high Harmonic Rejection for Wireless Power Transmission
The purpose of this work is to propose an efficient microstrip
rectenna operating on ISM band with high harmonic rejection.
The receiving antenna with proximity coupled feeding line
implemented in a multilayer substrate. The rectenna with
integrated circular sector antenna can eliminate the need for an
low pass filter (LPF) placed between the antenna and the diode
as well as produce higher output power, with maximum
conversion efficiency of 74% using a 1300 <symbol> load resistor at a
power density of 0.3 mW/cm square.
