The paper presents a novel approach to the syn¬thesis of non-conventional wire antennas exhibiting wideband or multi-band behavior. The approach is based on the Partic¬le Swarm Optimization method (PSO). For the fast wideband analysis, the Time-Domain Method of Moments (TD-MoM) is used.
In the first part, the numerical analysis of randomly ori¬ented wire antennas by the explicit form of TD-MoM is des¬cribed. In the second part, the multi-objective optimization of the wire antenna by PSO is proposed.
In the third part, the numerical example is shown: an antenna optimized for GPS is synthesized. The antenna is optimized for two frequency bands of impedance matching, uniform gain and circular polarization in the normal direction to the reflector.
