Reviewer 2 Report
The paper presents a linear array antenna resonating at 28 GHz of millimeter wave spectrum for 5G communication systems and AMC layer is designed to increase the radiation intensity and improving overall array gain. The presented work achieved the optimal performance in terms of fractional impedance bandwidth, realized gain, efficiency and excellent radiation performance features. The work has a certain worth and add some interest to the readers. However, I have some suggestions to further improve the quality of the manuscript.
1. Overall English writing of the manuscript should proof read from the native speaker.
2. The authors are suggested to highlight the key contributions and novelty of the manuscript in the introdauction.
3. I suggested authors to further add more recent quality research work published in the year 2020- 2022 and incorporate it in the revised manuscript.
4. Figure 2, Figure 5, Figure 8, Figure 15, replace |S11| (dB) to Reflection Coefficient (dB).
5. Figure 8 and Figure 9 should be merged together as you already shown the reflection coefficient and gain plot in Figure 2 and Figure 5. Moreover, I suggest you to maintain the quality of figures throughput the manuscript.
6. I see a lot of discrepancies in the measured results, Why is it so? Please explain the solid reasons of these discrepancies.
7. Figure 10 (a) – (c), I didn’t see the gain axis. How can reader understand the amount of gain of the proposed work? It is suggested to show the gain performance of the antenna array in the polar as well as Cartesian coordinate systems.
8. Again in Figure 17 (a) – (b), I didn’t see the gain axis. Please provide the gain axis so that readers can easily understand the amount of gain.
9. In the comparison table I see some typos particularly in the gain performance with AMC and without AMC. The authors are required to again have a look and modify it accordingly.
