Antenna Bandwidth Optimization by Genetic Algorithms with Single Frequency Simulation

Summary, in English

Antenna Q optimization by a genetic algorithm with method of moments simulation at a single frequency is described. The optimized antennas may have arbitrary shapes within a rectangular region. Simulations using a commercial tool show good agreement between the predicted and realized Q factor. Furthermore, comparison with the physical bound shows that the optimized antennas perform close to the optimum for many electrically small dimensions.
