Copy antenna design from PCA10040

[s700]

Dear,

I want copy antenna design from PCA10040 for BLE. Could you please help to provide antenna's spec, such as gain, efficiency, Radiation Pattern?

Thank you.

When you copy an antenna design, it will behave different on the new design. The antenna is strongly dependent on the ground plane, so changing the size and shape of it will change the antenna parameters as well. 

The DK antenna have a gain around 0 dBi. With a decent ground plane, you can probably expect the same. But the radiation pattern will not be the same.
