NFC Antenna (Component A1) in the reference designs for nrf52832

1.What are the dimensions of the NFC antenna (component A1) for the reference designs given in the design files here 

http://infocenter.nordicsemi.com/pdf/nRF52832-CIAA_Ref_Layout_v1.0.zip

In other words what can be the best antenna for that purpose. Can the layout be directly used for custom pcb? 

2. Where can i find the specifications and datasheet for the antenna that comes with nrf52832 development board

is it this one? 

3. What can be the best dimensions for a pcb antenna that i could give to the layout designers?

    1) The easiest way to find the dimensions of the NFC antenna is to open the gerber (or Altium) files supplied with the reference layout. That NFC antenna can be used on custom PCB.

     

    2) To my knowledge, there are no specifications/datasheet for the antenna.

    A NFC antenna should be designed so that it matches its usecase, size, shape, number of turns, etc.
