I don't how to search for it. It has only "4 4" written on it; I didn't get any search results from it.

Does anyone know what this SMD component is, and what it is used for?

It is a ceramic chip antenna, and it does what antennas usually do.

Its specs (but not its make and model) are in chapter 7 of the module's datasheet which can be found on Adafruit's website.

Maybe with this information you can google make and model, or find a similar one.
