I happened across this Q/A previously and the resources it provides are certainly useful. However, it doesn&#39;t address my question of how to integrate with the nrf51822 chip. If you have any further insight, I would be very appreciative.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/15710?ContentTypeID=1Tue, 11 Nov 2014 21:02:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:433b6ef8-460d-4ddb-b3c8-79109c89aa68John<p>The nrf51822 does not have a built in antenna. I think this question and answer may be useful to you to get going. It points to several white papers and downloads that should get you going on the antenna.</p> <p><a href="https://devzone.nordicsemi.com/question/1373/antenna-selection/">Antenna Selection</a></p><div style="clear:both;"></div>
