An Optimization Design Method for Dual-Band and Wideband Patch Filtering Power Dividers

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

This paper introduces a novel automated design approach employing both continuous and binary optimization techniques for the creation of dual-band and wideband filtering power dividers (FPDs). The methodology involves optimizing the multiple modes of a patch radiator to achieve dual-band and wideband functionalities. Simultaneously, the optimization process considers filtering properties, resulting in power dividers that incorporate filtering functions. The design procedure is highly automated, reducing the need for manual calculations and simulations. As a validation of the proposed method, a dual-band filtering power divider with center frequencies at 2.4 GHz and 6 GHz, and a wideband filtering power divider operating between 3.7 GHz and 5.25 GHz, are designed and fabricated.

Overall, the paper effectively communicates a well-structured and comprehensive methodology for automated design in the realm of dual-band and wideband filtering power dividers, backed by practical validation. The clear presentation and inclusion of specific design and fabrication details contribute to the paper's clarity and scientific merit. However, some points must be addressed:

1.       Introduction should be more developed.

2.       Figure 1 (a): What are the values of R1, R2, and R3?

3.       Figure 1 (b) includes R1 and R2. Explain why these two variable are different. What are the values of R1 and R2, and why you neglect their loss effect?

4.       Enrich the references by adding new related works.

5.       Figure 9: Magnitude values are missing.

6.       Figure 9: Explain why S23 follow the blue curve. I believe that this curve, as it is, presents a negative aspect in the design.  

7.       Conclusion should be expanded.

Comments and Suggestions for Authors

This paper provides a clear and concise method based on binary optimization algorithm for designing dual-band and wideband filtering power dividers (FPDs). This approach significantly reduces the need for manual simulations and human effort in FPD design. By accurately defining fundamental models and a fitness function for the FPDs, the algorithm produces effective solutions through multiple iterations.

Overall, this research work is interesting and valuable to the readers, but the authors should revise and improve this manuscript by considering the following comments and suggestions.

1-      It is better to add a section of equivalent circuit model of the proposed dual-band and wideband filtering power dividers.

2-      I recommend the authors to add some references related to the synthesis of filtering power dividers based on using different optimization techniques.
