14 Application example
The antenna is of a quarter wave type and is dependent on the groundplane area to complete the antenna
function. The antenna performance is also dependent on the size of the groundplane and the tranparent area.

Placement of the antenna
The antenna shall be placed on a transparent area without underlying groundplane at the edge of the
PCB oriented as above. Groundplane area surrounding the antenna should be with a clearence of
G=3-5 mm
Placement of 2.4 GHz module
To avoid losses in the strip line, 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.
Clearance
No components allowed within the clearence area with a minimum distance to other components,
C= 3-5 mm.
Note ! Incorrect implementation of the antenna will affect the performance.
