Research of Patch Antenna Loaded with Slot Split-Ring Resonators on Different Substrate Materials

In the era of rapid microminiaturization of electronic devices, where microstrip antennas become a key element, scientists around the world realized the urgent need to improve the imperfect characteristics of this type of antenna. This study is aimed at studying the use of dielectric substrates with various dielectric constants in microstrip antennas loaded with an annular open resonator. The HFSS computer program was selected to conduct a comparative analysis of various configurations. The simulation will be carried out for patch antennas with dielectric substrates made of RT Duroid material with a relative permittivity of 〖(ε〗_r) 3.2, Rogers with 〖(ε〗_r) = 3.2 and Bakelite with 〖(ε〗_r) = 4.4 and a thickness (h) of 32 mm. Directional patterns will be plotted for each variation, as well as bandwidth calculated. As a result of the analysis of the collected data, the optimal configuration with the best characteristics will be revealed. These results may open up new prospects for the application of microstrip antennas in various industries, stimulating innovation and advanced technological solutions.
