Tool/software:
Hello,
I am trying to model an antenna of the MMWCAS-RF-EVM in HFSS based on the dimensions provided in the 'AWRx Cascaded Radar RF Evaluation Module' user's guide. To achieve matching results, I need to know the substrate's properties: what dielectric loss tangent (tan δ) and relative permittivity (εr) were used, as well as the substrate thickness. Are there any other critical parameters to specify to accurately replicate the radiation pattern and S-parameters? Also, do the distances between the antenna elements shown in the figure significantly affect the results?
Sincerely,
Iheb SIFAOUI
