Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Dear authors;

1-Can you summarize in a few sentences what all this work is about at the end of the introduction?

2-Theabstract needs more interest and rewriting of some paragraphs.

3-There are still some aspects that can be improved (for grammar and punctuation). Improve the technical writing of your paper, where there are several grammatical errors and spelling I think they need to be checked out.

4-The conclusion needs more effort to elaborate on the achieved results with respect to future work,

5-There are still some aspects regarding the obtained results discussions that are missing. Can you please address your achievements well?

6-The practical part is very important, therefore, I’m asking about the radiation pattern measurements,

7-Why this design geometry, explain the design methodology and specify the novelty of your antenna structure,

8-Future work is an important part of the conclusion.

9-The results are still not matured well. Can you clearly mention what your objectives clearly for each result you got during the discussion process?

10- There are several relative works, I wish to discuss, based on adding such structures to the antenna. Can you please suggest your enhancements and advancements (if you would) over such as the following:

A- https://doi.org/10.1016/j.aeue.2023.154652

B- https://doi.org/10.1002/mop.33761

C- https://doi.org/10.36244/ICJ.2023.2.1

D- https://doi.org/10.32620/reks.2023.1.06

E- https://doi.org/10.1002/mop.33666

I loved this work and I feel it is very good. I hope these comments will help you improve this work after a major revision.

Regards

Reviewer #2: The authors presented their work, "Low Profile High Gain RHCP Antenna for L- Band and S-Band using Rectangular Ring

Metasurface with Backlobe suppression", which seems to be quite interesting and important from a research point of view considering its outcomes. However, some technical modifications are required before considering revising it.

First of all, the authors are required to highlight the need for the proposed metasurface antenna design by explaining its pros and cons over the ones reported in the existing literature. So, a brief inclusion of it is required in the manuscript.

The analysis of the metasurface unit cells is missing. On what basis it is working in the proposed antenna design needs to be explained.

Considering the attainment of circular polarization (CP) outcomes, it is significant to add the analysis in terms of electric field distribution, surface current distribution, radiation pattern, etc. In the radiation pattern, LHCP and RHCP components should be shown clearly.

The authors should try to plot the obtained results by using the plotting software.

Finally, a comparison table must be prepared, highlighting the performance aspects, mainly CP characteristics, of the proposed metasurface antenna compared to others.
