摘要：

This paper presents three resonant bands of microstrip monopole antenna for radio frequency energy harvesting applications. The proposed antenna has a good performance in GSM-900/1800 and GPS/UMTS bands. The rectifier circuit design consist of several rectifier branches to collect the largest amount of RF power, due to the non-linearity and the complex input impedance of the rectifying circuit, Therefore, an improved impedance matching technique is introduced which is aimed to improve the performance of the rectifier with a varying condition. The proposed antenna is printed on FR4 substrate with modified ground plane to achieve suitable impedance bandwidth. Two V shaped arms with optimized angle are integrated on the L shaped monopole radiator. Each arm is responsible for certain resonating frequency. The antenna operates at three frequency bands (GSM 900/1800, GPS and UMTS bands) with reflection coefficient below - 10 dB.
