Abstract

In view of the contradictory unity of growth and whiting in natural trees, Tree Growth Competition Algorithm was presented in this paper. The algorithm searched from a simple status to complex statuses with quick convergence. Then, the algorithm was applied to designing novel tree-shaped line antennas. A software package on automated design of tree-shaped line antenna was developed. Making use of it, a kind of tree-shaped line antenna was designed at the center frequency of 2.45 GHz and the model of coaxial feed. The simulation experiment shows its directive gain is higher than that of the traditional antennas in the same size.
