Rectenna for Wireless Power Transmission
2020Rectenna (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.
