Properties and technical applications of antenna arrays focused on a broadband signal

Background. Currently, antenna arrays focused in the near-radiated field zone are being actively studied. The basic properties and characteristics of focused antenna systems using narrowband signals are known. It is possible to expand the technical capabilities of devices using focused electromagnetic fields through the use of broadband signals. This article is devoted to a description of the properties and a number of technical applications of antenna arrays focused in the near-radiated field zone using a broadband signal.
