Simulate the Transmission Coefficient S_21 of Two Antennas

  Dear Community
  I am trying to simulate the transmission coefficient S_21 of two antennas that are far (20 times the wavelength) apart.
  At the moment I use FE-BI boundaries/boxes around both antennas and get more or less accurate results. But I would like more accuracy.
  Has anyone done this before? Any tips on how to get more accurate results?
  Many thanks in advance!

  Hi Alexander,
  Thank you for reaching out to the Ansys learning forum.
  The FE-BI boundary allows you to accurately analyze the two distant antennas with minimum resources. Please increase the accuracy of your model by tightening the adaptive pass convergence criterion.
  Hope this helps.
  Best regards,
  Praneeth.
