Abstract :
A finite difference time domain (FDTD) model is developed and validated against measured data for rectangular microstrip antennas. The FDTD model is then used as the fitness function in a genetic algorithm (GA). The GA-FDTD code is used to optimise a known patch antenna configuration and to evolve the same configuration starting with very limited knowledge. This was carried out to study the `search´ properties of the GA. The various fitness values obtained from the FDTD output data are used in a novel way to improve the search
