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. Electromagnetic 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.
