How to design antenna connection for BlueNRG?

[Pawe? Jab?o?ski]

Hi everyone,

I would like to design my own PCB with BlueNRG. It will be simple board with BlueNRG and H3LIS331DL sensor, very similar to STEVAL-BCN002V1. Schematic of this PCB is clear for me, but I don't have any expieriences of developing RF antennas. Datasheet of antenna's chip is very poor. Can someone give some solutions or design rules?

P.S. Where is it possible to buy STEVAL-BCN002V1?

Thanks a lot
