The use of microstrip and fractal antennas based on metamaterials in digital communication systems to increase their energy efficiency

The possibility of using metamaterials in the construction of microstrip and fractal antennas is investigated. The variations of the introduction of metamaterials considered in the work make it possible to achieve increased energy efficiency of digital communication systems, which makes it possible to create devices with improved characteristics and expanded functionality. Various variants of microstrip and fractal antenna devices were modeled using CST Studio software, which meet modern requirements for optimizing the size and improving radiation parameters. The paper considers two structures: a torn ring resonator (SRR) and a complementary resonator with detachable rings (CSRR). The possibility of using the studied antennas in 5G, Wi-Fi standards (2.4 GHz, 5 GHz, 6E standard) is considered, the advantages of using both metamaterials and fractal geometries to increase energy efficiency and noise immunity of digital communication systems are shown.
