Antennas for SIM7600G-H-M2 4G Communication Module

Hi!
 

I have a Lattepanda delta 3 and I have bought a module for mobile network and am now looking for three antennas for this. It's a bit of a jungle for me when it comes to finding antennas, so I'd like to hear from you to see if you can recommend any antennas that fit.

It seems that the antennas I got with the latte panda also fit the module. But what are these called?
 

Thanks in advance!

The module that I have is the following
