Abstract
This paper proposes a reflectarray antenna exhibiting dual-polarized characteristics and operating in the frequency of 27. 4-28.1 GHz. The dual-polarization in the reflectarray is obtained by illuminating the polarization-insensitive surface with a dual-polarized microstrip patch antenna. The reflectarray surface consists of 17 x17 unit cells, with a cell size of 0.47λ x0.47λ. The f/d of the antenna is 0.4, which signifies the compactness of the design. The aperture efficiency of the design is 20%, and it demonstrates a maximum gain of 22 dBi in beams that are polarized orthogonally. The proposed design provides a method to obtain dual polarization where the two ports of the patch antenna can be excited to get two orthogonally polarized radiation fields. The antenna can find application in full-duplex mm-wave communication. The concept of the design is practically fabricated and verified through measurement. The simulated and practical results show a good agreement.
