Dear researchers,

I presented an equivalent RLC circuit model for a dielectric resonator antenna (DRA). During the review process, one of the reviewers suggested that the equivalent circuit model validation would benefit from quantitative error analysis to evaluate the model's accuracy more precisely.

I would like to ask for your guidance on how best to address this comment.Should I apply a quantitative error metric such as RMSE based on the S-parameters (e.g., comparing S11 from ADS vs. HFSS), or is there a more accurate or widely accepted method specifically for validating RLC circuit models of antennas?

Any suggestions, feedback, or references would be highly appreciated;

Thank you
