Abstract

The microstrip patch antenna with the feeder gap is improved with nematic liquid crystal of type E7 embedded material, which has replaced the part of dielectric substrate. The investigation is focused on the impact of the geometrical parameters of the fragment of embedded material to the S parameters of the microstrip patch antenna. Authors presents initial simulation results to investigate how embedded material influences and changes typical antenna electrical characteristics. The computer-based modeling is performed with Ansys HFSS®. The embedded material has allowed to control the resonance frequencies and directivity and also to improve the gain of the antenna. The best case is obtained with –21.76 dB return loss at 2.4 GHz frequency when the length and width of the fragment of embedded material were equal to 1 mm and 20 mm respectfully. The designed antenna is characterized by good directivity when all energy is concentrated in main lobe.
