Abstract :

The usage of impedance matching materials in antenna systems is a promising direction in the development of modern radar stations that allows unifying nomenclature of radiating elements. One of possible appliances of impedance matching materials is transfer of working frequencies of radiating elements to bands with greater wavelength. The usage of several impedance matching mediums, for example, with 2 r r ├?┬Á = ├?┬╝ = 4 r r ├?┬Á = ├?┬╝ = 8 r r ├?┬Á = ├?┬╝ = 10 r r ├?┬Á = ├?┬╝ = allows to extend waveband of the radiating element by 2, 4, 8 and 10 times. We have provided some works of foreign scientists and suggested some methods to use impedance matching materials to increase working wavelength of existing radiating elements. We have provided the results of numerical electromagnetic simulation of slotted waveguide radiating element, whose operating wavelength is increased by 10 times. Dimensions of impedance matching antenna are limited by sphere radius and the possibility of creating materials like that for required bandwidth. Key problems with the dimensions of antennas are relevant in the long-wave band (frequencies below 1 GHz), while such materials are created for this bandwidth.
