What is te antenna connected to it ?

where can I buy it alone ?

thanks
 

It looks like a patch antenna. To reduce its size, some makers use a dielectric substrate with certain permittivity.
 
This is no doubt a GPS ceramic antenna with dielectric constant of around 22.0 and thickness of about 5mm. We usually use a 28dB 3-stage LNA to enhance the gain to about 30dBi (28dB LNA + 3dBi Antenna gain) which communicates to the satellite.
you may contact www.lambdoid.net for more details
 
Thanks for all of you

I conclude that it is a ceramic patch

also I don't think it is active, I think it is a passive antenna (without LNA)

Thanks
