A Jug-Shaped CPW-Fed Ultra-Wideband Printed Monopole Antenna for Wireless Communications Networks

Round 1

Reviewer 1 Report

The authors have presented a UWB jug-shaped antenna for wireless communication. The simulated design is validated with measurements. Following are my comments:

• Brush up the abstract and introduction to highlight the contribution and novelty.
• What are the potential applications of the designed antenna with the gain limitations in the range of 2-4.1 dBi? Please highlight this in the Introduction.
• In Table1, add a column of antenna types for each comparative study.
• How did you design the circuit model? Why 3 parallel RLCr branches? What is the theory behind this? How did you get the lumped component values?
• What is the use of the presented circuit model? What is the relationship between the lumped components and design parameters (dimensions) of the proposed antenna?
• How can we enhance the antenna gain?

The authors have presented a UWB jug-shaped antenna for wireless communication. The simulated design is validated with measurements. Following are my comments:

Comment#01:   Brush up the abstract and introduction to highlight the contribution and novelty.

Authors Response: We are thankful to the reviewer for mentioning this comment. We have updated this in the revised version.

 

Comment#02:   What are the potential applications of the designed antenna with the gain limitations in the range of 2-4.1 dBi? Please highlight this in the Introduction.

Authors Response: We are thankful to the reviewer for mentioning this comment. Since the applications of the antennae can be predicted by the operating band, compactness of the size, and the direction of the radiation pattern. In the introduction section, the authors have highlighted the potential applications of the antenna.

Comment#03:   In Table1, add a column of antenna types for each comparative study.

Authors Response: We are thankful to the reviewer for mentioning this comment. We have updated this in the revised version.

Comment#04:   How did you design the circuit model? Why 3 parallel RLC branches? What is the theory behind this? How did you get the lumped component values?

Authors Response: We are thankful to the reviewer for mentioning this comment. The circuit model is being designed using advanced design system (ADS) software. Since there is not fully RLC branches in the circuit. Although there are three RC branches connected in series with resistors and Inductors. This circuit model is being designed to achieve UWB spectrum and to compare it with the UWB band achieved from the proposed antenna. Regarding the lumped component values. It does not depend on the values of the antenna dimensions. Just the optimum values of the lumped components have been chosen at which the UWB spectrum is achieved. By varying the values of the lumped components, the frequency of the antenna shifts, and the bandwidth will be changed.

 

Comment#05:   What is the use of the presented circuit model? What is the relationship between the lumped components and design parameters (dimensions) of the proposed antenna?

Authors Response: We are thankful to the reviewer for mentioning this comment. There is no major relationship between the lumped components of the circuit model and the dimensions of the proposed antenna. Since both are different things but the S11 achieved from the circuit model is compared with the S11 of the antenna and there is a good agreement between them.

Comment#06:   How can we enhance the antenna gain?

Authors Response: We are thankful to the reviewer for mentioning this comment. The gain of the antenna can be increased by increasing the size of the antenna. Since, in our article we have mentioned that we have achieved the UWB spectrum with compact size of the antenna. But we also have compared our proposed results with the previous latest research in Table 1.

Reviewer 2 Report

A manuscript titled “A Jug-Shaped CPW-Fed an Ultra-Wideband Printed Monopole Antenna for Wireless Communications Networks” has been presented. Manuscript is well presented however following comments would be helpful to further improve the manuscript.

• Use same multiply symbol throughout. As at some places “X” is used and at some places it’s multiply sign. See table 1, column 3 and 4.
• There are various simple UWB designs reported in literature, what is the advantage of this complex design over the simple designs.
• Add more discussion on modifications introduced in each design phase and its significance (i.e. ANT 1 to ANT IV).
• In return loss plots, use |S11| (dB), as they are magnitude plots and not the complex plots.
• Update Fig. 7 (a) if possible, as it shows un-soldered connector to PCB.
• Add radial scale for radiation plots in Fig. 8, which are missing.

Comment#02:   There are various simple UWB designs reported in literature, what is the advantage of this complex design over the simple designs.

Authors Response: We are thankful to the reviewer for mentioning this comment. It is right that the shape of the proposed antenna is a bit complex, but it has improved parameters as compare to the previous simple designs as can be seen in Table 1. The Jug-shaped structure help to achieve the whole UWB spectrum as well as the size of the proposed antenna became more compact than other simple designs in the literature.

Comment#03: Add more discussion on modifications introduced in each design phase and its significance (i.e., ANT 1 to ANT IV).

Reviewer 3 Report

A compact size an ultra-wide-21 band (UWB) printed monopole antenna with improved gain and efficiency is presented in this article.

This is an interesting article that does not require major changes and can be published in its current version.
