A novel design of multi patch antenna

Energy harvesting from ambient has become a major area of research. This paper presents a multi patch microstrip fed antenna designed for multiband radio frequency energy harvesting. Partial-Ground has been used for bandwidth improvement. The antenna operates at 3 to 6 GHz range with return loss reaching up to -27dB. The power received by antenna can be fed to a RF to DC converter with proper matching and amplification to obtain a decent DC voltage at the output to power low power devices.
