Simplification of Feed System of Circular Array Antenna Using Genetic Algorithm
The desired directivities and gains of array antenna with a large number of radiating elements are easy to obtain. By considering array antenna as an aggregate of subarrays, the design, production, inspection and maintenance are simplified, and the reduction in cost can be carried out. Genetic Algorithms are “global” numerical-optimization methods, patterned after the natural processes of genetic recombination and evolution. In this paper, circular array antenna is divided into subarrays. Then, the source distribution of circular array antenna can be approximated as a Taylor distribution by combining subarrays having the same source distribution using Genetic Algorithm so that the simplification of feed system becomes possible.
