Abstract:A computer program is presented that can assess the impact of small. random design perturbations on the performance of a planar array antenna of dipoles. Expressions for the expected or average radiation pattem and the change in directivity for a perturbed planar array are developed and used in the program. Translational errors in the positions of the elements, errors in the element's drive amplitude and phase, nonidentical element pattems. and missing elements are accounted for in the expected radiation patte… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
