The purpose of this paper is to design and simulate a unit cell that is wideband and multi-polarized for a reflect-array antenna. Bandwidth of structure is greater than 70% of X and Ku bands for satellite applications that reached from two printed dipoles and asymmetric arrow head shape in structure for multi electric and magnetic resonances and used thicker substrate for enhancement of BW by stack up of substrate with different layers. Depending on the antenna usage, the proposed structure can provide dual or triple polarization switching through the use of one or two control bits. Among the innovations of this structure compared to other activities, it can be said that the switching capability to support multiple polarizations occurs in a common wide bandwidth, or in other words, each of the switching modes is not in different single frequency or a bandwidth of frequencies. Comparing the switching modes of the proposed design with other existing control structures, the feature of maintaining the polarization of the feeding antenna or converting it to orthogonal polarization in different bits distinguishes the proposed structure. The proposed design has a new geometrical structure and considering that it can have the main polarization of the feeding antenna, its orthogonal polarization and even circular polarization in any switching mode, it has a relatively simple geometry, which reduces the complexity of the construction mechanism.
