Abstract
This paper introduces a highly efficient rectenna (rectifying antenna) using a binary optimization algorithm. A novel pixelated receiving antenna has been developed to match the diode impedance of a rectifier, eliminating the need for a separate matching circuit in the rectenna's rectifier. The receiving antenna configuration is fine-tuned via a binary optimization algorithm. A rectenna is designed using optimization algorithm at 2.5 GHz with 38% RF-DC conversion efficiency when subjected to 0 dBm incident power, with an output voltage of 815mV. The proposed rectenna demonstrates versatility across various low-power WPT (wireless power transfer) applications.
