Minimum Meshing Wire Segment Radius

User: "Altair Forum User"

Hello, 

I am trying to simulate a probe fed proximity coupled patch antenna (center frequency= 4.5 GHz). When I am taking the meshing wire segment radius to be lambda/10 or lambda/20, it is showing an error message which says that the wire segment radius is too large. What should be the correct wire segment radius in this case?

Furthermore, I am observing that as I am reducing the radius to around 0.5 mm, it is showing a drastic improvement in the reflection coefficient and VSWR plots. How far can I go on reducing the wire segment radius? What is the minimum value?
