14.2 Example carrier board

Since the RF performance of the module with the on board antenna is strongly dependent on the

proper location of the module on its carrier board, Figure 6shows the reference carrier board which

was used during testing by Telegesis.

Figure 6: Reference Board

Finally to provide a good reference ground to the on board antenna, the carrier board should have

a ground plane spanning no less than 40 x 40mm. In many cases a smaller ground plane will

suffice, but a degradation in radio performance could be the result.
