Abstract:
Abstract: To design ultra-wideband antennas, an efficient method is used. The method combines an improved quantum genetic algorithm (IQGA) and the volume surface integral equation based on the method of moment. Computation time is saved by using optimum uniform approximation that accelerates the analysis of the ultrawideband antenna’s characteristics in calculating fitness. A novel microstrip-fed UWB antenna with dual notch bands in 3?4 GHz and 5?6 GHz is designed and fabricated. Comparison between the optimized and measured voltage standing wave ratios shows that the method is correct and effective.
Key words: ultra-wideband antenna, quantum genetic algorithm, method of moment, volume surface integral equation, optimum uniform approximation, voltage standing wave ratios
