Reviewer 1 Report
Modeling and analysis of axially symmetric radiators with a narrow funnel-shaped radiation pattern has been reported in the paper. Proposed work is interesting and useful for antenna engineers.
My comments are as follows:
- Kindly give the description of all parameters mentioned in section 2 (e.g. µp+ )
- Figures quality can be enhanced.
- It would be comparable and easy to understand the radiation patterns at different frequencies (k values) when plotted in a single graph. Combine plots for different frequencies in Figure 2. Similarly for Figure 4, 5, 7.
- Is this model valid for magnetic materials such as ferrite (finite permeability)? What parameters will be changed or newly introduced if magnetic material is considered?

Reviewer 2 Report
Some comments are given as below:
1, Please give much more details in Fig.1, such as the meanings of the black and yellow regions and their materials.
2, The formula in section 2 and 3 are too many, I suggest the authors can simplify them or add them into appendix so that the length of this paper can be shorter.
3, Some information in the figure can be seen very clear, such as the Lprot in Fig.2.
4, Please add the structure parameters of the gratings (l, d, h and c in Page 12, paragraph 2) into the diagram of Fig.1.
5, In Page 12, the frequency "k=35", I am not very clear about it. It is a normalized frequency or f=35GHz?
6, Please let me know the operating frequency of the antenna.
