| Abstract: | This paper investigates a hybrid approach of genetic algorithm (GA) and simulated annealing (SA) for the fast optimal design of broadband loaded helical antennas. The loading circuit parameters, locations of the loads along the antenna, as well as matching network parameters, are optimized simul taneously. An efficient approach is applied in the design procedure for the fast calculation of the impedance matrix equation when the loading configurations are changed, which greatly enhances the optimization efficiency. Two broadband min iature loaded helical antennas are designed successfully, one of which is manufa ctured and the numerical result agrees well with the experiment result. |
