Rectenna for Wireless Power Transmission

Rectenna (rectifying antenna) is designed for better conversion efficiency. The obtained efficiency is 57.8%. The return loss obtained is −25.043 dB. The working characteristics of the rectenna are determined by the characteristic curves which depend on the input power. The power varies from −20 to 20 dBm. This paper focus on the microwave power transmission and conversion efficiency and how efficiently the conversion takes place. The rectifier circuit was designed and simulated in advanced design system (ADS) software while the antenna was designed using high-frequency structure simulator (HFSS).
