match, hence, affecting the pattern. The particular factors are the board material and thickness, shields,
the material used for enclosure, the board neighborhood, and other components adjacent to antenna.
3.5.1 General recommendations
 Metal enclosure should not be used. Using low profile enclosure might also affect antenna tuning.
 Placing high profile components next to antenna should be avoided.
 Having holes punched around the periphery of the board eliminates parasitic radiation from the board
edges also distorting antenna pattern.
 ZigBit module should not be placed next to consumer electronics which might interfere with ZigBit's RF
frequency band.
