WT50RW02 OEM Manual and User Guide
The antenna traces need to routed STRAIGHT OUT OF THE NAD TO THE NEAREST NAD EDGE.
The lines need to be tapered from 433micron to the 967micron width gradually but quickly.
Figure 6-6
These line widths may vary depending on the stackup selected for the main board.

• Signals should be routed along similar route path, but separated by ground trace.
• Trace impedances should match the table, either as microstrip or stripline.
• Total length for both signals should match the table.
• Spacing to ground or other signals on outside of bundled signals should match the table.
