Table 23: Coplanar microstrip specification

The GND spacing requirements of the NINA ANT and U.FL connector RF pins are greater than the 
spacing requirement of a 50 

Ω

 coplanar microstrip. However, the increased spacing to GND does 

not affect the trace impedance significantly for short trace lengths of width and height shown in 
Table  23.  Consequently,  the  trace  impedance  for  traces  with  these  dimensions  is  still  close  to 
50 

Ω

.
