Abstract |
A method for the design and optimisation of wide-band printed planar monopoles using a genetic algorithm is presented. This novel technique employs overlapping sub-patches which ensures electrical contact in such constellations where two sub-patches are touching only at the corner, hence re-ducing losses. The method was used to design a wideband monopole antenna with application in higher cellular, WLAN and UWB. Furthermore, the technique is modified for multi-goal optimisation to achieve multiple bands and reduce the lower edge frequency. The best solutions were prototyped and a full experimental evaluation was made. |
