Engineering Reports, Volume 7, Issue 9, September 2025.In this study, a new plan for routing radio transmitters is presented using an algorithm compatible with RFEH. The proposed algorithm is based on the genetic algorithm (GA), and in an innovation, using the HPBW in the GA creates a population for initial sampling dependent on the receiver antenna.
