Rectenna System Design in L-Band (1–2 GHz) 1.3 GHz for Wireless Power Transmission

The purpose of this paper is to present a rectenna system design for working in L-band (1–2 GHz) 1.3 GHz, for that purpose it used a Rectangular Microstrip Patch antenna in transmitting and receiving side of antenna having a lesser return loss 40 dB at particular design frequency 1.3 GHz. In receiving side It use a another rectangular microstrip patch antenna with DGS Structure to avoid the unnecessary harmonics and reduce the size of receiving antenna. Diode use for convert RF power to DC power is a M/A COM flip flop Schottky diode MA4E1317. This kind of rectenna can be extended for scientific contribution to wireless power transmission by applying array of rectenna and high gain transmitting antenna, like Horn antenna or array of microstrip patches for larger scale of wireless power transmission. Maximum diode conversion efficiency can be achieved up to 38.15%. Effitiency is low because of not using array of microstrip patches or any high gain transmitting antenna to avoid the complexity of the system.
