A review of high performance ultra-wideband antenna array layout design

An overview of many of the new and powerful methods for generating ultra-wideband array layouts is given, focusing mainly on the contributions of the Computational Electromagnetics and Antennas Research Lab (CEARL) at Penn State. Evolutionary strategies and optimization algorithms are used exclusively with most of these design techniques, allowing for easy creation of arrays of various sizes and properties. These ultra-wideband array design methods span multiple dimensions, ranging from simple linear arrays to planar and volumetric types. A selection of design methods will be covered here along with example arrays, their performance, and suggested applications.
