Flexible Patch Antenna for the XBee-PRO SX

Hi, I am looking at U.FL antenna options for the XBee-PRO SX.

My question is whether or not a certain flexible patch antenna is compatible with the FCC/IC antenna certifications listed in the user manual.

The antenna in question is the following:

The antenna is omnidirectional and has a fairly low gain compared to other antennas listed in the manual. However, I am unsure what category of antenna the flexible patch would fall under.

Can I use this antenna without the need for additional compliance testing?
Any additional information you can provide on this subject would be appreciated.

Thank you,
