A subarraying technique based on a novel genetic algorithm (GA) whose operators have been suitably customized in order to deal with integer variables is presented in this paper. The method is aimed to prevent the generation of high-level quantization lobes in the scanned radiation pattern by properly combining a given number of clusters selected from an arbitrarily defined alphabet of tiles of various...
The design and optimization of a Yagi array of miniaturized monopoles top-loaded with Peano space-filling curves was presented. Unlike conventional Yagi arrays of dipoles and monopoles, the design of a Yagi-PTLM array requires the use of evolutionary programming (EP) optimization in order to determine the inter element spacing, element heights, and Peano top-load sizes for an array design with sufficient...
Corrugated horn antennas are frequently used as the feed elements in reflector antennas for satellite and deep space communications. A particular application is the multifrequency feed horns for the reflector antennas of the JPL/NASA Deep Space Network (DSN). In this application, it is desirable to design a horn that has a nearly perfect circularly symmetric pattern (i.e., identical E- and H-plane...
