10.3.2.2 Transmission Line Considerations
The RF signal from the module is routed to the antenna using a Coplanar Waveguide with ground (CPW-G)
structure. CPW-G structure offers the maximum amount of isolation and the best possible shielding to the
RF lines. In addition to the ground on the L1 layer, placing GND vias along the line also provides additional
shielding.
Figure 10-3 shows a cross section of the coplanar waveguide with the critical dimensions.
Figure 10-4 shows the top view of the coplanar waveguide with GND and via stitching.
