Development of Antennas Theory and Technique Based on Modulated Impedance Structures in Lviv Polytechnic University

In this article, the principles, methods and models of antennas based on periodically impedance structures at the Institute of Telecommunications, Radio Electronics and Electronic Engineering of the Lviv Polytechnic University are developed. The results of development of the original design of existing samples of disk impedance antennas with transverse radiation of an electromagnetic field, antennas based on a cylindrical impedance structure and the results of studies of their spatial ring antenna arrays radiation patterns, end flat antennas of surface waves based on periodically inhomogeneous al ribbed structures with impedance grooves, the results of experimental studies of the characteristics of the formation of diagrams directivity are presented of for cases of changes in the period of impedance inhomogeneities. These results using the method of Newton's analogies are the basis for the development of emitting structures for nanoscale technology.
