Dear all,
I'm trying to make a parallel stubs filter. It consists in some parallel microstrip lines finished in ground.
I designed it and then I simulated with ADS. I had no problems until here, the simulation was kind of what I'd expected.
The problem came when I tried the EM simulation. I defined the substrate and I put the pins, but when I run the simulation, the program deletes the ground pins of my circuit, and it simulates as if there was no ground pins.
Lately I tried the same circuit but using coplanar waveguides instead of microstrip lines and I got the same result.
Why isn't my layout reading the ground port?
Thanks!
