Directional Properties of 3D Fractal Hybrid Antennas Based on Metamaterials

The basic requirements for dron antenna -ensuring the continuity of the radio channel in all the spatial evolution of the eguipment carrier and multifrequency, as different in functional purpose channels have different carrier frequencies. It must be compact, lightweight and durable. Previous researchers used multiple antennas concurrently. The goal was to create a new type of antennas for drones - hybrid 3D fractal antennas of a pyramid form with the use of metamaterials. Similar structures have not yet been explored by other authors. It was obtained the frequency properties for reflection coefficients, standing wave ratio, spatial magnitude distribution and radiation pattern.
