For kicks, we tore down a popular BTLE (Bluetooth smart) module, the RF Digital RFD22301, which is based on the nRF51822. Pretty straightforward layout; wished they'd broken out a few more I/O. Note that the metal can has been removed.
They use a fractal-style antenna ... for cost savings, I'm not sure why they didn't go with an IFA, or maybe even a PIFA.
