[BG96] Antenna trace width design (50Ω)

[rab]

Hello

I have UMTS&LTE EVB KIT.
Look at the picture. This is a photo of board with BG96 from this KIT.

The width of the track which connect UFL and BG96 ANT_MAIN pin is less than 1mm.

In according with this:

the track width should be 3mm width, then impedance is 50Ω.
Why the KITs antenna trace is so thin?

Hi rab,
Your impedance is microstrip design, and our EVB is coplanar waveguide design, and lines width are different with the height of H.
