Placement of antenna
The antenna shall preferably be placed at the edge of the PCB oriented as above so that the antenna
blade can be placed outside the application’s casing. Other placements and orientations and size
of grounplanes are possible, but this will affect the performance. Avoid active components near the
antenna.
Placement of 2.4 GHz module
To avoid losses the module shall be placed as close to the antenna as possible.
Strip line
The strip line must be dimensioned according to your specific PCB. (see fig 1). No crossing strip lines
are allowed between the strip line and its ground plane.
Via connections
To avoid spurious effects, via connections must be made to analogue ground.
Component matching
Component values are depending on antenna placement, PCB dimensions and location of other
components.
DC Block
Might be needed depending on RF Module configuration.
Clearence area
Avoid components and parts close to the antenna.
