Modifying Port Area in ADS-2008 (or 2009) Layout for EMDS simulation

Question asked by engrvivs on Jun 23, 2012
Hi,

This is related to layout design in Agilent's ADS-2008 (or 2009) for EMDS simulation. I want to know if the port area, as shown by EMDS > 3D EM Preview, can be modified by the designer? By port area, I mean the port boundaries, depicted as shaded portions in the attached figure.

I found that ADS software automatically sets the port areas as follows:
ADS-2008  =>  Wp = 7xWstrip;    Hp = 4xHsbstrt
ADS-2009  =>  Wp = 21xWstrip;    Hp = 11xHsbstrt
where, 
Wp and Hp => the width and the height of the port area, respectively; 
Wstrip => width of the microstrip line
Hsbstrt => height of the substrate

Moreover, it would also be beneficial if someone can suggest appropriate port dimensions for correct simulations of microstrip line based structures in EMDS.

Thanks in Advance,
Vivs
