Wi Fi Antenna Modules- How to attach

[mhef]

I replaced a Dell lid. The new lid had antennas but no green module at the top. And the old one's antennas are too short for this lid. How do I attach the antennas to the module?

I would need to see the little board they attach to. I imagine they either snap into place or they need soldered to the module.
