This thesis deals with two methods of antenna miniaturisation techniques: integration of fractal geometry into antenna design and application of metamaterials. The proposed antenna system is based on a fractal antenna covered with a layer of metamaterial. The fractal antenna is designed by applying the second iteration of the Peano curve to a 29.8 × 29.8 mm² microstrip patch antenna. The metamaterial is a dielectric substrate with an array of modified split-ring resonators. FR-4 is used as the antenna substrate and metamaterial material. The antenna characteristics are evaluated using the finite element method in Ansys HFSS software. The results obtained show that the proposed antenna operates at three frequencies: 2.1 GHz, 4.0 GHz and 4.6 GHz and shows an improvement in gain at all three frequencies up to 8.1 dB, 8.6 dB и 9.7 dB respectively.
