Jenkins, who denied the charges, was found guilty of all 24 charges of match fixing against him, and he also accepted one charge of betting on darts for which he was given a suspension of 12 months which will be concurrent with the 11-year ban.
The 54-year-old, who reached the 2007 World Championship semi-finals, has also been ordered to pay costs of 17,580.03 pounds.
Jenkins has until May 6th to appeal the decision, and the DRA say there is no suggestion that other players from the matches in question were involved in any way.
