Reviewer 3 Report (New Reviewer)

1.  The explanation related to papers cited need to be added. Particularly for papers cited in [16-20].

2. The authors should add the details about the measurement set up used for verification along with the photographs

3.   Conclusion can be improved by mentioning the specific contribution of the paper

4.  The authors should mention the application of the proposed design of antenna. It is not mentioned where we can use the proposed design of antenna

5.   It is observed that the gain of the proposed antenna is less as compared to other cited methods in a comparison table. The authors should justify the reason for the same

This manuscript is a resubmission of an earlier submission. The following is a list of the peer review reports and author responses from that submission.

Round 1

Reviewer 1 Report

In the paper authors propose design has polarization diversity by using two conventional truncated corner square patches. The manuscript has major anguage and writing issues e.g in Abstract

(It is noted that other reported MIMO designs with MS in literature can achieve high isolation by keeping large spacing between the MIMO elements............... This distinguishes the proposed work to the others. For verification, the measured results of a fabricated antenna prototype demonstrate that a wide operating bandwidth of 11.3% (5.0–5.6 GHz), in which isolation is always better than 20 dB and realized gain is higher than 4.4 dBi, can be attained.)

 

I suggest a comprehensive rewrite for the manuscript.

 

Reviewer 2 Report

1.  Kindly justify how a metasurface can enhance the bandwidth.

2. Kindly mention axial ratio bandwidth in the abstract.

3.  For verification, the measured results of a fabricated antenna prototype demonstrate 18 that a wide operating bandwidth of 11.3% (5.0–5.6 GHz), is this the correct value of bandwidth?

4. Kindly mention the dimensions of the antenna in the Table.

5. To prove the CP radiation, kindly refer to the below papers, cite them in your paper and show the time-varying analysis for CP radiation in desired bands:
