FOOTPRINT, MECHANICAL AND PCB DIMENSIONS
The antenna footprint and mechanical dimensions are
presented in Figure 7. Optimal tuning is adjusted according
to PCB layout.
For additional mechanical support, it is recommended to
add one drop of heat curing epoxy glue.
" The glue dot should not overlap with any of the soldering
pads
" Apply the glue dot at the center of the antenna.
" The glue dot area secures the chip firmly to the PCB
