Abstract EN
In order to reduce the time of designing microstrip antenna, this paper proposes a self-renewing fitness estimation of particle swarm optimization algorithm (SFEPSO) to improve the design efficiency.
Firstly, a fitness predictive model of the particles is constructed according to the evolution formula of particle swarm optimization (PSO).
From the third generation of the algorithm, the fitness of particles is given by the prediction model instead of the full-wave electromagnetic simulation.
Aiming to keep the right direction of evolution, the prediction model will be proofed every N generation during the optimization process.
If the prediction model accuracy is lower than the threshold, it will be updated and then continue iterating until the particles satisfy the demands.
Compared with the traditional optimization method, this method greatly reduces the evaluation time and improves the design efficiency.
The method is validated by the optimized design of E-type dual-frequency microstrip antenna and WLAN/WiMAX multiband antenna.
The optimized results show that the purpose of rapid optimization can be achieved while ensuring the design accuracy.
