12-4 Judgement standard
The judgement of the above tests should be made as follows:
13 Hazardous Material Regulation Conformance
14 Application example
General
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.
Cadmium and cadmium compound.
Organic brominated compound (PBB, PBDE)
Polychlorinated biphenyl (PCB)
Polychlorinated naphthalene (PCN)

Visual inspection - Normal apperance with no obvious cracking, peeling-off.
Electrical inspection - The DUT satisfies the VSWR specification throughout the 2.4-2.5 GHz band.
Placement of the antenna
The antenna shall be placed on a groundplane area, preferably at the edge of the PCB oriented as
above.
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.
