Microstrip Ground Reference

The Microstrip will have a ground reference on the adjacent inner layer and top
(same) layer as the Microstrip. The Nemo2 reference evaluation board has an
adjacent ground plane inner layer below the Microstrip. The top layer has a ground
reference to the Microstrip as well. The spacing between the top ground references
is crucial and should be at least 3x the width of the Microstrip. The Nemo2
Evaluation board uses 1mm spacing from the Microstrip to the top layer ground
reference.
