Reviewer #1: The authors have presented a two-element antenna array with dual-sense circular polarization, wideband operation, and high isolation characteristics. While the article is well-written and the discussions are engaging, several points need to be addressed before accepting this manuscript with minor revisions.

1. Describe the simulation method in the introduction section.

2. Elaborate on the novelty of the work in the introduction section. Clarify the unique properties of the proposed structures compared to existing literature.

3. The title of this manuscript relates to Metasurface-based polarized antenna, but there is no description of metamaterial and metasurface devices. To help the readers comprehend, address this issue and include other approaches of optical metasurface-based devices (Plasmonics, 2024, 19(1), 481–493, and https://doi.org/10.1007/s11468-024-02219-2) in the introduction section.

4. Fig. 2 illustrates the simulation result of the designed structure, but there is no information on the simulation methods in the text. Please clarify the simulation method and setting in more detail in the text.

5. Clarify the impact of structural parameters on device performance in the text.

6. Clarify in more detail the mechanism and the result discussion of Figs. 5, 7, 12, 13, and 14.

7. Ensure to check and correct any typos and grammatical errors throughout the manuscript.

Reviewer #2: In this paper, a two-element MS-based antenna array with wideband operation and high isolationhas been investigated. The paper is Well written and well presented. The contributions are novel and justified.

However, include state of the art work to further strengthen the literature, like https://doi.org/10.1371/journal.pone.0288793

https://doi.org/10.3390/sym15091641
