The 21-year-old midfielder comes hot on the heels of a raft of new signings - with Carden putting his own stamp on the New Bucks Head squad.
Ward is a product of the Stags' academy - but he left the club back in 2019 to join Barnsley.
While at Oakwell he was sent out on loan to FC United of Manchester, Gainsborough Trinity and Ilkeston Town - before returning to Mansfield in 2021.
So far this season, the midfielder has made seven appearances for Nigel Clough's side - but now he will spend a month trying to help the Bucks climb clear of the National League North drop zone.
Ward is one of a number of recent signings to arrive at the New Bucks Head - with Liam Nolan, Brayden Shaw and Jordan Piggott all arriving in recent weeks.
Prior to that Carden also signed Mace Goodridge and Andre Wright - with a number of players also leaving the club.
