How to make GPS module work with antenna if it doesn't have the breakout board?

Hi guys,
I bought a few GPS modules and they're just chips without the breakout board. A few of them have integrated antennas and my code worked fine with them, but 1 module doesn't have the antenna, I tried running the code with it but it never found GPS, I think I have to solder an u.fl connector to the antenna pin on the chip (can anyone tell me if it's pin ANT_ON??), and add some more codes to it but I'm not sure what to add.
Here is the information I found on the datasheet.

I'd guess from the datasheet that pin 11, RF_IN is the one you want to connect the antenna to. ANT-ON probably turns power on and off for active antennas.
