Abstract

In this paper, five suggested unit cells are presented and compared for the design of a 28-GHz reflectarray antenna that can be used for 5-G mobile base-stations. The unit cells of these reflectarrays are built with combinations between octagonal rings and octagonal patches. The CST microwave studio is used in all design stages. All reflectarrays have an area of 10λ × 10λ with element size λ/2 × λ/2 and focal length equal to 10λ. A reflectarray antenna with size 15λ × 15λ is built for one of the unit cells with element size λ/2 × λ/2 and focal length 10λ to enhance the gain. Center feeding is used with a pyramidal horn antenna. Simulation results show that the unit cell composed of two octagonal rings with an octagonal patch inside gives a high gain with a quite large bandwidth.
