Design of a Crooked-Wire Antenna by Differential Evolution and 3D Printing

Antenna design often requires dealing with multiple constraints in the requirements, and designs can be modeled as constrained optimization problems (COPs). However, are usually very strange, then feasible solutions hard to found. At same time, robustness for antenna is an important consideration well. To solve above issues, combination of differential evolution algorithm (DE) 3D-printing technique presented a new crooked-wire antenna. In process, DE adopted handle since simple efficient finding solutions. The objective COP, which sum variance gain, axial ratio, VSWR over frequency band, used enhance widen band without additional computational cost. precision fabricating ensured by using 3D-printing.
