Abstract | ||||
h: 0px; "> This paper presents two different polarization independent unit cells for reflectarray antenna that are suitable for 5-G mobile base-station applications and compares between them. The first unit cell is composed of two concentric rings and a cross loop inside and the second one contains three circular rings for bandwidth enhancement. These reflectarrays are designed around 28 GHz with 10×10 aperture dimensions. The unit cells dimensions are 0.5×0.5. A pyramidal horn antenna is used for the feeding purpose. The F/D ratio is taken as one. All the simulation stages are carried on the CST microwave studio. The simulation results show that the design with the UC2 gives a better performance than the design with UC1 from the aperture efficiency and the side-lobe level perspectives. Both designs offer a good cross-polarization level. | ||||
