I can't find any reference to the antenna on the data sheet. I am not convinced it has one.

I do see the data sheet saying that pin LA is "Antenna Connection 1" and pin LB is "Antenna Connection 2". Those two contacts are available with different metal options - more evidence that they intend you to attach an antenna to the two pins.

On the NXP web site you can find 50+ page reference documents telling you how to simulate various kinds of antennas. 

Most often, you buy these chips as straight dies, and attach them entirely yourself. This form of package allows virtually anybody to use the chips and make a flexible tag.

Thanks,

gopi.
