blueNRG USB Dongle Dev Kit Chip Antenna

Hello,

I'm in the process of replicating the bluetooth radio design in on pg. 37 here:

http://www.st.com/st-web-ui/static/active/en/resource/technical/document/user_manual/DM00099259.pdf

, and I'm having difficulty locating the AN2051-254 2.4GHz bluetooth chip antenna used in the design.

Other than contacting the antenna manufacturer (

http://www.rainsun.com

) in Taiwan I think, does anyone have any tips relating to how I can source the chip antenna used in the design or know of a similar antenna that has worked with the dev. kit schematic.

Since I have limited access to the kind of equipment I'll need to tune an optimized matching network, I'm trying to minimize the number of variables required to design a functional circuit.

Thanks.
