Hi All,

I want to add discrete ports to a monopole planar microstrip antenna in CST Studio Suite. The antenna model looks like below. It does not have a ground plane underneath so I am not sure how I can simulate it. Second image shows how it connects to the rest of the PC with the matching network. I want to apply the port at the Green arrow location.

1. How can I add ports (discrete/waveguide) to a such a circuit?

2. Is there is a better way to simulate this Antenna?
