Synthesis of unequally Spaced Antenna Arrays by a new Differential Evolutionary Algorithm

Chuan Lin, Anyong Qing and Quanyuan Feng

Abstract


The differential evolution (DE) algorithm with a new

differential mutation base strategy, namely best of random, is

applied to the synthesis of unequally spaced antenna arrays. In the

best of random mutation strategy, the best individual among three

randomly chosen individuals is used as the mutation base while the

other two are for the vector difference. Hence a good balance of

diversity and evolution speed can be obtained. An indirect coding

method is utilized to convert the constrained synthesis problem to

an unconstrained one. The effect of angle resolution of the radiation

pattern is also discussed. Simulation results demonstrate that the

new DE algorithm is promising.
