The reviewer for the paper we recently submitted mentioned that our step sizes at which we are measuring the gain in XFdtd may be too large. They pointed out that there appear to be "lobes" at 400 MHz. I ran the antenna we presented in the paper through XFdtd using a step size of 5 degrees (what we've been doing) and a step size of 1 degree (the reveiwer's recommendation). Attached are antenna responses for these two different step sizes at 200 MHz and 400 MHz. Qualitatively, there are noticeable differences in the "jaggedness" of the 400 MHz plot and how extreme the minima and maxima appear, but the basic shape is preserved. We can try to do a more quantitative analysis (ex: run these through AraSim), but doing so may be more time intensive than necessary considering that AraSim may require 5 degree steps and that adding these images to an appendix may be sufficient anyway.
