摘要：

A rectenna designed with a microstrip harmonic-rejecting circular sector antenna at 2.4 GHz is proposed. As compared to a conventional microstrip square-patch antenna, the circular sector antenna using inset feeding exhibits high reflection coefficients at the second and the third harmonics generated by a diode. The rectenna with integrated circular sector antenna can eliminate the need for an lowpass filter (LPF) placed between the antenna and the diode as well as produce higher output power, with maximum conversion efficiency of 77.8% using a 150-Omega load resistor.
