PJ O'Connell scored an early goal for Antrim and the Ulster side went on to hold a 1-11 to 0-12 lead at the break.
Saffrons forward Paul Shiels was in superb form and he slotted over his 11th point before O'Connell netted again to put Antrim six points ahead.
Marty Kavanagh's late penalty gave Carlow hope but Antrim held on.
Kavanagh hit the net with five minutes remaining to close the gap to three points and set up a tense finale.
