| Abstract | ||
| The current work presents a novel cylindrical dielectric resonator (CDR) antenna geometry operating at 28 GHz for fifth-generation wireless communication networks (5G). Because of its high radiating power factor, the used dielectric resonator is regarded as a promising new candidate in the field of antennas. The CDR antenna is made up of a FR4 Epoxy Resin substrate with a relative permittivity of 4.4 and a height of 1.8 mm, to which we added a dielectric resonator with a relative permittivity of 8.3, a height of 1.5 mm and a radius of 1.34 mm and it fed by a single microstrip line. The designed antenna geometry was simulated and optimized with the electromagnetic solver HFSS, and the results were validated with the CST microwave studio software. The results allowed us to obtain an antenna radiation at the desired frequency of 28 GHz with an interesting return loss value, a good radiation pattern, a high gain, a large bandwidth and a high directivity. As a result, this antenna is suitable for a wide range of wireless satellite applications. | ||
