Formulation of Optimization Problems with Radiation Field Phases as Design Variables for Pattern Synthesis of Linear Antenna Arrays
文献摘要：
Pattern synthesise of antenna arrays is usu-ally complicated optimization problems,while evo-lutionary algorithms(EAs)are promising in solving these problems.This paper does not propose a new EA,but does construct a new form of optimization problems.The new optimization formulation has two differences from the common ones.One is the objec-tive function is the field error between the desired and the designed,not the usual amplitude error between the desired and the designed.This difference is benefi-cial to decrease complexity in some sense.The second difference is that the design variables are changed as phases of desired radiation field within shaped-region,instead of excitation parameters.This difference leads to the reduction of the number of design variables.A series of synthesis experiments including equally and unequally spaced linear arrays with different pat-tern shape requirements are applied,and the effective-ness and advantages of the proposed new optimiza-tion problems are validated.The results show that the proposing a new optimization formulation with less complexity is as significant as proposing a new algo-rithm.
