The RF signal from the device is routed to the antenna using a Coplanar Waveguide with ground (CPW-G) structure. The CPW-G structure offers the maximum isolation across filter gap 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 the coplanar waveguide.
Figure 10-4 shows the top view of the CPW with GND.
Table 10-4 and Table 10-5 provide the recommended values for 2-layer boards and 4-layer boards, respectively.
