Antenna Orientation Recommendation

3.4
The Antenna in this module is designed to provide the best possible LoS range in the direction indicated in this
illustration.

Mounting Information

3.5
The Figure below shows the PCB layout recommended for a ZigBit module. Neither via-holes nor wires are allowed on
the PCB upper layer in the area occupied by the module. As a critical requirement, RF_GND pins should be grounded
via several via-holes to be located right next to the pins thus minimizing inductance and preventing both mismatch and
losses.
