Abstract :
In this paper a planar broad-band antenna, which can be used as a ground penetrating radar, is designed by a combination of a genetic algorithm (GA) and a method of moments (MoM) technique. The GA optimizes the shape of the metallisation pattern in order to minimize the return loss in the chosen frequency band of 1-6 GHz, while the return loss is evaluated with a MoM-analysis. The optimization is made more efficient by applying the direct matrix manipulation (DMM) method. In order to distinguish symmetric and non-symmetric objects, an antenna which detects cross-polarization is used.
