A Multi-Bandwidth Reconfigurable Patch Antenna for Devices in WLAN and UWB Technology Applications

Round 1

Reviewer 1 Report

In this paper, authors have presented the design of a multiband reconfigurable antenna. The results confirm the multiband reconfigurable operation. The design is interesting. Following are the suggestions to the authors:

1.       Please include the structure of the paper at the end of the introduction section. Some more recent literature review related to multiband antennas should be included.

2.       In equation (1) (page 3) , h is defined as the thickness of the antenna, it should be thickness of the substrate, please check.

3.       Figure 1 (page 3) should be presented in two subfigures e.g. (a) top view, (b) back view.

4.       The dimensions of the presented antenna should be summarized in a table.

5.       The efficiency of the antenna should be included. A table for gain, efficiency and directivity for different frequencies should be included.

6.       As suggested above, some more recent references related to the multiband antennas such as ‘A multiband antenna for biomedical telemetry and treatments’, ‘A microstrip antenna using I-shaped metamaterial superstrate with enhanced gain for multiband wireless systems’,  ‘A single-fed multiband antenna for WLAN and 5G applications’ etc should be included.

7.       Page numbers in ref [6] are missing. Page numbers of ref [25] are missing. In ref [37], ‘Ghz’ should be written as ‘GHz’. Please incorporate the above comments, I would like to see the revised paper.

Minor editing of English language required.

Round 2

Reviewer 1 Report

Authors have addressed the comments in the revised paper. Following are the suggestions to the authors: 1. On page 1, '1' after first affiliation is not required. Please check. 2. In the introduction section, some paragraphs such as third paragraph on page 1 and few paragraphs on page 2 are very small. These should be rearranged. 3. In the last paragraph of introduction section on page 2, section 2.4 should be replaced by section 3. Please check. 4. In Fig. 11, please provide the subfigure titles as (a) 2.5 GHz, (b) 4.4 GHz.

Author Response

All comments have been addressed:

1. the "1" at the end of the affiliation was a typo and has been removed
2. the paragraphs have been rearranged to avoid having many small paragraphs
3. the section number has been corrected, now it says section 3
4. Figure 11 now has a description of the frequency of operation in the captions
