In this paper we propose a Rectenna for the purpose of RF Energy harvesting, it is non 50 ohms antenna. The proposed antenna is fabricated on a low cost FR4 substrate with the dimensions of the antenna 28.30mm (L) × 38.03mm(W), it is fed with a microstrip line feed technique. This antenna is tri-band antenna, operating at the resonant frequency of 2.47 GHz, 4.39 GHz and 6.49 GHZ i.e. S-Band (2-4GHz) and C-Band (4-8 GHz) C band of microwaves spectrum. The simulated results indicate a reflection coefficient well below −10 dB at the frequencies of interest. The antenna is designed using FR4 substrate with thickness of 1.6 mm and simulated results are obtained on HFSS software. Simulated result shows that this antenna is found suitable to be connected to a DC rectifier circuit to for energy harvesting.
