Hello,
I have previously created a product using the nRF8001 chip a year ago using a PCB antenna design. At the time the enclosure for the PCB was RF transparent and the antenna was working nominally. A new revision of the enclosure had to be produced to meet higher tensile strength requirements and Carbon fibre was the material that was selected to reach these requirements. Unfortunately, as Carbon fibre is not RF transparent, the connection to the nRF8001 is not stable anymore and the mobile application can no longer successfully connect to the chip.
To fix this I want to be able to break out the antenna of the chip to the outside of the enclosure using preferably a U.FL connecter. I took a look at the datasheet and there was no specific information on the schematic or PCB layout for use with a U.FL antenna. I found that the Development Kit for the nRF8001 has a board with an SMA connecter but I could not find a schematic or payout for that either. If someone could please give me a link to the schematic and PCB layout for a design using the nRF8001 with a U.Fl or SMA antenna that would be much appreciated.
Thanks in advance!
