Thanks All.
I took your advise and went thro the manual. I am now facing problems in analysis.
1. I have made a small 2D rectangle in the yz plane just below the inset feed, 50ohm line. I have now used this as the face for excitation as lumped port.
My air box doesnt touch the patch. it is lamda-by-four length away frm the ground.
Yet I get these errors:

1.Adaptive Passes did not converge based on specified criteria.
2. When I analyze the sweep and wish to get RL, the error is"St is not a function name.

Please help..

1. right-click on the setup in your Analysis menu. select 'Convergence'. You can take a look at the Max. Mag. Delta S. Let us know how much this and how many passes have been used. You can either increase the maximum number of passes (or) increase the maximum acceptable delta S.

2. What is your solution type: Driven Terminal or Driven Modal ? Remember to choose the appropriate type when creating the reports. 'Create Terminal Solution Data Report' (or) 'Create Modal Solution Data Report'
