The width of the GND plane to the sides the module will impact the efficiency of the on-board chip antenna. To achieve optimal per-
formance, a GND plane width of 50 mm is recommended. See 4.17.1 Antenna Radiation and Efficiency for reference.
7.2 Proximity to Other Materials
Avoid placing plastic or any other dielectric material in close proximity to the antenna.
Any metallic objects in close proximity to the antenna will prevent the antenna from radiating freely. The minimum recommended dis-
tance of metallic and/or conductive objects is 10 mm in any direction from the antenna except in the directions of the application PCB
ground planes.
7.3 Proximity to Human Body
Placing the module in contact with or very close to the human body will negatively impact antenna efficiency and reduce range.
