Determining the Direction of Radio Wave Reception for Maximum Radiation Using Genetic Algorithm and RF to DC Conversion Efficiency Analysis

Abstract

Analyzing the amount of energy received from radio waves can be effective in routing radio wave radiation. In this study, a new plan for routing radio transmitters is presented using an algorithm compatible with radio frequency energy harvesting (RFEH). The proposed algorithm is based on the genetic algorithm (GA), and the output voltage of the wireless energy harvesting system (rectenna) is the observation parameter. The algorithm first samples the environment around the receiving antenna on the azimuth axis and then on the elevation axis. Algorithm simulations for energy received from one transmitter and several transmitters have been done in Matlab. In an innovation, using the HPBW angle in the GA creates a population for initial sampling dependent on the receiver antenna. The HPBW parameter of the receiver antenna in the proposed scheme is essential in determining the number of primary samplings. The analysis of the proposed algorithm for HPBW < 45 can increase the number of samplings and improve the routing accuracy with the least iteration. In this study, the signal radiation path can be estimated by knowing the available radio frequency, without the need for other transmitted signal information, and with a simple design.
