The Pole, who reached the final of Wimbledon last year, was in control from the start as she broke twice to take the first set in 43 minutes.
Ivanovic was more competitive in the second, breaking twice herself, but the former world No 1 also dropped serve three times to allow Radwanska to complete the victory.
Radwanska will meet Sara Errani in the last eight after she came through 5-7 6-4 6-3 in a tough battle against Carla Suarez Navarro.
The fifth seed, last year's runner-up, had eased through her first three rounds but there was nothing comfortable about her victory on Sunday.
At 5-5 and deuce in the first set, Errani doubled over in pain and took a medical time-out, complaining that she could not breathe properly. Suarez Navarro went on to win the game and the set but Errani recovered.
The Italian said: "I start to feel like a knife was under my ribs. Every time I was breathing it was very painful on this point.
"I knew it wasn't muscular, but I couldn't stay up. So I called the physio and she told me that I had the diaphragm totally blocked and she tried to release it a bit. After that it was much better.
"It's still painful touching it, and I will go to the physio for sure. It's never happened to me before and it was a very strange feeling."
