The Rolling Stones guitarist was commended at the industry prize-giving ceremony after just a year of hosting his own show on station Absolute Radio.
The judging panel called the star: "An amazing character with a really innovative programme.
"Ronnie has lived the life of a thousand men and you feel like a child sitting at his feet as he unfolds his rarefied story book."
The musician collected his award shortly after British comedian Frank Skinner - who won the Best Entertainment Programme accolade for his eponymous show - and said: "This means more to me than it means to Frank, I think, because I'm the newcomer."
James admitted listening to the radio played an integral part in his early career, telling BANG Showbiz: "When I hear my own songs on the radio now, it reminds me of being a kid and used to listen to the radio, dreaming of wanting to write songs and get on the radio.
"It reminds me of listening to Radio 2 on a Sunday with my dad. I have the radio on a lot at home in the mornings and it's a good rejuvenator for the day."
Other winners at the ceremony - which was held at the Grosvenor House hotel in London - included broadcasters Jeremy Vine, Zane Lowe and Jenni Murray, while UK Station of the Year was named as commercial station talkSPORT.
