Antenna Module Inquiry: Microwave Incident

My friend microwaved my phone, the one I'm actively using to post this, the battery seems fine, it is capable of charging and everything else seems perfectly fine after the two seconds of microwave radiation, 5 minutes of black screen and 30 minutes of angry cursing, but my cell service in fact is not, it can not detect service but it is in fact capable of connecting to wifi, my IMEI is still accessible so I know that it has to be the antenna module, is it possible to repair it without replacing the part and is it feasible for a vaguely experience person such as myself?
