Hi
I'm simulating a two layer PCB layout in ADS, which has an SMA connector to a coplanar transmission line. The figure shows how the ports are connected to the SMA connector. For simulation purpose I've removed the PTH VIA from the signal feed. In the EM setup the port P1 is made + and P4 is made - .
Is this the correct way to model the ports for vertical SMA feed for S-Parameter simulations?
S11 without the SMA connector layout is around -35db, but for the configuration as shown in the fig. its around -20db. Am I doing anything wrong here?
