Hi everyone:) I am doing my project in antenna and filter design in ADS software..designing of antenna is over.my problem is the filter am supposed to design is of DGS (Defected Ground Structure).Actually i dont know how to make changes in ground plane in ADS momentum.please do any 1 help me??/??
Is it possible to design DGS in ADS software??????
 

The GND can not be defected in ADS because GND is infinitive underneath of the structure ( by definition of Moments Method) that's why I think that is not possible.Instead, HFSS or CST or EmPro can be used because there isn't such constraint in these softwares.
But nevertheless you can create a seperate GND different than global GND of Momentum but I have some doubts about its accuracy.
To my knowledge, these structures need 3D FDTD.
