  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.
