Sample Antenna Reference Designs
This section presents PCB designs which combine ZigBit with different antennas: PCB onboard antenna, external
antenna and dual chip antenna. These antenna reference designs are recommended for successful design-in.
The symmetric dipole antenna above has been tuned for the particular design. The ‘cut-and-paste’ approach would
not guarantee optimal performance because of multiple factors affecting proper antenna 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.
