7.2.4 Transmission Line Considerations
The RF signal from the device 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 7-6 shows a cross section of the coplanar waveguide with the critical dimensions.
Figure 7-7 shows the top view of the coplanar waveguide with GND and via stitching.
