,nYes, reception should be higher for free space rather than with any obstacle between those antennas.nCould you please try with a smaller value of 'delta' (or tight convergence) and check the S21 value? Check with value 0.1 or 0.005. nAlso, try with any other metal material (PEC, copper, etc..) instead of glass and check the S21 value?.Best Regards,n
