FMB130 firectional antenna (bluetotth or rfid)

Friends,

I am using FMB130 for a project.
I need more accurate identify approaching vehicles (better gps function) on a static GPS (like a stationary gps checkpoint)
My GPS (stationary checkpoint) can be moved from one place to other.

Plus, i would like to read approaching vehicles from one direction only (directional)

So, can i plug directional antenna RFID or bluetooth on FMB130? Any advice?

Regards
