PCB reference designs for nRF51 dk

[RSK]

Are there any reference designs available for nRF51 Development kit using a chip antenna and not the PCB antenna ?

@RSK: We don't have any reference design that uses chip antenna. But any 2.4GHz antenna with 50 Ohm impedance should work. A PI network for tuning should be added. Or you can use the 3rd party module as suggested by michaeld.
