Abstract:
A Theoretical analysis by Genetic Algorithm for optimization of important parameters (Directivity, Radiation Power, Impedance etc.) of magnetically biased microstrip antenna fabricated on ferrite substrate is reported. The effect of magnetic field (Ho) on ferrite antenna during electromagnetic propagation is incorporated in function analysis with the help of extraordinary propagation constant (k), which is new one in this type of optimizing analysis.__ampersandsignnbsp; Functions for the fitness of the GA program is developed using cavity model of the analysis of microstrip antenna. The genetic algorithm was run for 500 generations. The probability of crossover was varied from 0.7 to 0.85 and the probability of mutation was varied from 0.001 to 0.002. The computed results are in good agreement with the results obtained experimentally.
