5.6.3. Antenna-Gain and Radiation Pattern
If S42/AI is integrated into an end product while the recommendations depicted
in 6.4 Placement Recommendation are maintained, the following typical antenna
radiation patterns can be expected.
Radiation Pattern will depend on the end products PCB size, masses in the antenna
environment, housing material and geometrics. Typical antenna gain is about +2dBi.
