As preliminary information for Figure 22, the traces width of all sections is 0.2mm and the length of each section, starting from the LGA
pad to J1 connector are: LGA pad to G2: 5.65mm; G2 to J1: 7.35mm. However, refer to associated Gerber files for more accurate details
on dimensions and refer to Trilliant Networks Inc for more details on the Gerber files. Table 8 shows the parts used in the reference trace
design.

5.4.4 Design validation & production procedures
To verify compliance of the reference trace, a coupon must be requested with every manufacturing panel form and for which the
characteristics are described in the Gerber files. Part of these characteristic are shown in Figure 23. Then a network analyzer is used to
measure the impedance of this coupon in order to validate the antenna trace.
