Unveiling New IoT Antenna Developments: Planar Multibeam Metasurface Half-Maxwell Fish-Eye Lens with Wavelength Etching
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe manuscript“Unveiling New IoT Antenna Frontiers: Planar Multibeam Metasurface Half Maxwell Fish-Eye Lens with Wavelength Etching” introduces a groundbreaking antenna system, the Metasurface Half Maxwell Fish-Eye (MHMF) Lens directive antenna, tailored specifically for IoT networks. Designed to operate at 60 GHz, this antenna ingeniously integrates a dipole antenna within a parallel-plate wave-guide to illuminate a Half Maxwell Fish-Eye (HMFE) lens. It represents a significant achievement in the pursuit of improved connectivity and performance for IoT systems. The MHMF lens directive antenna is a cutting-edge IoT technology that addresses the difficulties of signal transmission and reception in highly interconnected environments. Its distinctive design and demonstrated efficacy make it a highly promising advancement in this field. This work is quite impressive, and there are some minor questions that need to be addressed.
1. Please highlight the advantages of Half Maxwell Fish-Eye (HMFE) lens over other lens. In addition, it is recommended to cite more recent references for comparison.
2. Only give the abbreviation at the same time as the full name for the first time, and it is recommended to use the abbreviation later.
3. Please check the format, for example, lines 165 and 166 need to be aligned.

Reviewer 2 Report
Comments and Suggestions for Authors1. English writing should carefully checked through the entire manuscript.
2. Figures 3 and 4 have the same choice of substrate material but different characterization parameters, which are modified to be consistent for the sake of rigor throughout the text.
3. The design methodology steps for realizing the Half Maxwell Fish-Eye are from step 1 to step 8, introducing specific improvements to the design or structure herein as specific steps are realized.
4. For the proposed antenna cross-polarization, radiation efficiency and other metrics need to be given specific results figures.
5. Although the radiation efficiency is only reported for a single frequency in [37], the radiative efficiency is still necessary as a comparative metric with other work.
6. The directional map above the antenna is changed by a lens structure, which has a rigorous and rational design theory, but lacks innovation in structure.
Comments on the Quality of English LanguageEnglish writing should carefully review the entire manuscript and appropriately streamline the narrative

Reviewer 3 Report
Comments and Suggestions for AuthorsThis manuscript presents MHMF lens directive antenna for IoT networks. This work is well presented with extensive analysis and excellent figures. Major revision is recommended. Detailed comments are:
1. The authors claims a groundbreaking antenna system is introduced in this work. The question is what are the groundbreaking features of the developed antenna? What are the advantages over other’s work? Over the comparison table, it is not obvious and difficult to see the groundbreaking feature of this work.
2. For the title of this work, it is expected to see the multibeam feature. The question is where is the multi-beams? How to achieve the multi-beam feature in the developed antenna? How about the tested multi-beam results? Radiation patterns at two edge and center frequencies should be provided for full demonstration of the developed antenna system.
3. The authors claims it is an antenna system. What is the full view of this system, we can only see some key but isolated components in the figure. Can the authors give the final assembled antenna system and the antenna system under S-parameter and radiation patterns measurement?
4. The authors say it is for IoT application. Can the authors give a figure to depict the detailed IoT application scenario for this antenna system? This will make the whole work more interesting.
5. Speaking of the IoT, do the authors have some results relevant to IoT applications? Such as how the developed antenna can efficiently improve the IoT system compared to others work? How the multi-beam feature enhance the IoT connectivity?
6. Final comment, how about the simulated and measured gain and efficiency performance of the developed antenna system?
