microstrip bandpass filter at 2.4 GHz

hey, i am designing microstrip bandpass filter st 2.4 GHz using FR4 as substrate (dielectric constant-4.4, tand 0.002, height-1.58 mm , thickness-0.035, cond-4.1+7) using ads 2011.10. My schematic is giving good result but on generation of layout, the layout results are coming entirely different from the schematic results..Can u help me with the possible solutions or corrections need to b done so that my layout S11 S21 plots come similar to schematic to some extent..
Below are the results i am getting(attached).

The coupled lines are not alligned correctly in the layout. This has caused both conductors of outer coupled line sections on input and output of the filter to be shorted to the next coupled line section. Schematic simulation would not take such a misallignment into account but EM simulation certainly will. You need to adjust the W1 and W2 paramaters on the MCFIL so that the coupled lines allign correctly.
