| Abstract: | The Competitive Algorithm of Simulating Natural Tree Growth,a novel optimization algorithm,was applied to antenna design by calling the numerical electromagnetic simulation software based on Finite Element Method（FEM） to implement the automated antenna design,and then a novel microstrip plane tree-shaped antenna with end-fire characteristic was designed.This antenna maintained the end-fire radiation pattern with S11-10 dB in the frequency band from 5.77 GHz to 5.93 GHz,and the end-fire gain is 5.4 dBi at the frequency of 5.8 GHz.According to the simulated result,a prototype of the antenna was fabricated and tested.Good accordance was obtained between simulated and measured results. |
