A new optimization scheme combined with the space-mapping technology and the jumping-gene genetic algorithm (JGGA) is to replace the conventional direct genetic computational type of the optimization scheme for antenna designs. This utilizes the assumption that there is an equivalent linear mapping between the design-parameter ratio and the response ratio in two spaces on the condition that there...
A sickle-shape patch dipolar antenna is proposed for UWB use. When optimizing the proposed antenna by genetic algorithm, it not only has a wide impedance bandwidth, but also has a constant radiation pattern across the operating frequency band. Thus, distortion can be reduced throughout the entire UWB frequency range, making it a good choice for UWB systems.
