It is difficult to synthesize the antenna directly in practical lessons in general theory of antennas with students. The approximate method is proposed for solving the synthesis problem based on the minimization of the functional representing the distance in the functional space with a quadratic metric between the normalized desired antenna pattern (AP) and some normalized AP with unknown amplitude and phase distribution (APD) of the field in the aperture. In this case the AP does not necessarily have to relate to the class of realizable ones, and APD of the field, while functional is minimized, can be selected from the set of the functions suitable for implementation.Validity of the method is tested on the example of synthesis of a linear antenna with the APs for which the APD is accurately known. The recommendations for conducting practical lessons are given.
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.
