A planar dipole antenna is analyzed using time-domain integral equation (TDIE) method. In order to compensate the influence of the shape of the excitation pulse and to suppress dispersion phenomena, an inverse filtering is applied in the time domain using the cyclic convolution.
In order to keep computations in the time domain, an objective function is formulated in terms of time-domain parameters. A global optimum is sought by genetic algorithms and particle swarm optimization.
The antenna is required to exhibit the maximum bandwidth, the maximum gain, and the minimum dimensions at the same time. Since these objectives are conflicting, a multi-objective approach is applied, and the set of Pareto optimum solutions is computed.
