UWB Antenna Optimization Using Micro-genetic Algorithm

  • Received Date: 11 Dec 2006

  • To meet different designing requirements and improve the efficiency of antenna design,a new method,finite-difference time-domain method(FDTD) combined with a micro-genetic algorithm(MGA),was proposed for design of ultra-wide band(UWB) antennae.An analysis shows that MGA makes an optimization converges faster than a genetic algorithm(GA) does.As an example,a TEM horn antenna was analyzed to show the feasibility of the new method.The processes of the radiation in the parallel-plate transmission line and in the TEM horn antenna were obtained with FDTD,where an UWB electromagnetic pulse was fed through a coaxial transmission line.The information about the antenna in time domain was also acquired.The performance parameters were calculated based on the acquired information,and followed by normalization.The normalized performance parameters were used to set up a fitness function,and the physical structure of the antenna was then optimized with the MGA.
