You obviously damaged the Antenna or something of sorts when you dropped it. You can fix it next time by spending $40 bucks on a case so when you drop your phone that doesn't happen.
Otherwise, if you aren't too tech savvy, and based on you posting this, I am guessing you aren't. You can take it to an authorized Samsung repairer. Or call 1-800-Samsung

Mhinc is right, the problem is with the antenna. Take your phone to service point
