Jumping Genes Tackle UWB- Antenna Design Requirements

摘要

Wideband-antenna design can be quite formidable-especially for the handheld terminal, as compromises must be made for frequency band, size, pattern, gain, and simplicity. Recently, a planar UWB monopole antenna was proposed by the City University of Hong Kong's Xue-Song Yang, Kai Tat Ng, Sai Ho Yeung, and Kim Fung Man. This antenna was designed using a newly developed evolutionary optimization algorithm.rnOne recently proposed multi-objective optimization algorithm adopts a fast non-dominated sorting approach, crowding mechanism, and elitism strategy. To do so, it combines parent and offspring populations and selects the best N solutions (where N is the population size). A somewhat new genetic operator dubbed "jumping genes" has now been proven to be a much more computationally efficient algorithm whenrnboth convergence and diversity are required. In this work, the jumping genes play a significant role with the fast crowding technique when an ultimate set of non-dominated design solutions are being considered.
