Microstrip Patch Rectenna for Electromagnetic Wireless Power Transfer at 2.45 GHz

This paper presents a rectenna design intended for use in power harvesting and wireless power transfer applications. The proposed rectenna is based on a rectangular microstrip patch antenna printed on both sides of an FR4 substrate. The rectenna is designed for operation in the WLAN frequency range (2.45 GHz). The received power is into an RF-to-DC converter based on the BAS40 series diode. The antenna and rectifying circuit were assembled and measured. The resulting assembly was tested in laboratory conditions, measured results were in agreement with the simulation.
