Recently designed a patch antenna in Sonnet on FR4 board. The design went well, and the measured S11 is very similar to the predicted S11. But the measured gain shows the FR4 material is low Q, and lossy enough to effect the gain significantly.
Is there some way for Sonnet to predict the S21 of this antenna, showing the loss of gain due to the poor FR4 tan del? Or do I need to switch over to HFSS or CST to do this? I a do not necessarily need the full radiation pattern, just a boresight prediction of gain due to dielectric loss.
