what is the antenna connected to this module

Hello

This a picture of SkyLab SKM53 Module

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.

the antenna is an embedded patch antenna.. http://skylab.en.alibaba.com/product...lab_SKM53.html
if you want to buy the antenna then first make sure in which frequency range you will be working in, and you can't buy only the antenna part of this module. you have to search for some other compact antenna which can meet your requirements.

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.

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
