Figure 3-12. PCB Layout with Dual Chip Antenna Module recommended for ATZB-24-A2
Normally, chip antennas are more tolerant of the board or enclosure materials in ZigBit's neighborhood
as well. However, general recommendations given above for the PCB antenna design still apply.
The board design should prevent propagation of microwave field inside the board material. Electromag-
netic waves of high frequency may penetrate the board thus making the edges of the board radiate,
which may distort the antenna pattern. To eliminate this effect, metalized and grounded holes must be
placed around the board's edges as shown.
Since the design of dual chip antenna is intended for installation on FR-4 board 1.6 mm thick, the
antenna performance may only be guaranteed for the particular board type and thickness.
