doubt with MWO

Hi, I've and important question about Microwave Office. I've designed a printed antenna that works perfectly when I simulate it but the measurements in laboratory are completely different. I think the problem could be in the ports. I use an edge port to feed the antenna using coplanar feeding, but I don't know if the simulator understand where is the ground or if I have to define it elsewhere ( once the antenna is built I feed it using SMA connector ans I put the ground pins at both sides of the coplanar line ). Any help could be grateful

Hello Javirulo

See the attached documents from Sonnet Software...

It is some what similar simulation setup you need to do for CPW applications in MWO...
