Hello all,
I am trying to simulate the attached antenna in Sonnet. It is a single-side PCB antenna. Metal trace lines are on top of a dielectric substrate (e.g. FR4) and NO metal on the backside of the substrate.
Since the antenna is fed with a coaxial cable, I would like to simulate the same port condition, i.e. one arm is connected to a signal port and the other one is connected to ground. Please note that the two arms are not connected electrically.
Because it is an antenna, I don't want to use wall port which put my antenna too close to the conductive wall affecting the performance. Can anybody suggest how to set up this kind of port in Sonnet?
Many Thanks : )

to be more specific, I would like to simulate an unbalanced input for an antenna, i.e. one signal one ground. But not a balanced input, i.e. one +ve signal one -ve signal.
Is this kind of difference taken care in simulation software like Sonnet?
