| Abstract | ||
| In this research, the rectangular patch antenna dimensions are reduced by means of the Genetic Algorithm. Genetic algorithms are capable of handling a large number of design parameters and work for optimization problems that have discontinuous or non-differentiable multi-dimensional solution spaces, making them ideal for antenna optimization. In the present work, a genetic algorithm has been used for size reduction in microstrip patch antennas. A method for reducing the size of microstrip patch antennas by up to 45% by removing rectangular slots from the metal of the microstrip patch is presented. A solid patch antenna that resonates at (8.5 GHz) is forced to resonant at (10 GHz) through the removal of the different shaped slots. Given the number and shape of the slots, the genetic algorithm is used to optimize the size and location of the slot on the patch. | ||
