when I modal a open transition such as microstrip,I found that the result of S21 of the modal with radiation boundary around is smaller than that with a non-radiation air box around.
for example.
radiation boundary existing: S21 equal to -2.4dB
non-radiation air box existing: S21 equal to -1.0dB
which result is correct?who can give me some ideas?
thank you
