•
At least 10 mm clearance between the antenna and the casing is recommended. If the clearance
is less than 10 mm, the antenna performance can be adversely affected.
•
The module shall be placed such that the antenna faces outwards from the product and is not
obstructed by any external items in close vicinity of the products intended use case.
•
Keep a minimum clearance of 5 mm between the antenna and any casing. Also, keep at least 10
mm of free space around the metal antenna including the area directly below it. If a metal
enclosure is required, use NORA-W361 and an external antenna.
•
It is beneficial to have a large solid ground plane on the host PCB with a good grounding on the
module. Minimum ground plane size is 24x30 mm but more than 50x50 mm is recommended.
