McIlroy carded a final round three over 73 to tie 23rd on six over for the tournament.
The Holywood golfer's final round got off to a bad start with a bogey on the first.
He recovered with two birdies on the third and seventh holes, but two further bogies and a double bogey on the 12th took the fizz out of the world number six's day.
McDowell, meanwhile, finished his final round with an even par 70 to end the tournament on seven over to tie 28th overall.
In opening three holes McDowell put two birdies on the board.
However the world number 22 went on to bogey the fourth.
He managed to get one more birdie at the 10th, but bogies on the 12th and 13th ensured an even par round to cap off his tournament.
Martin Kaymer dominated the competition from the off to claim his second major title.
The German finished eight shots ahead of his nearest challengers on 9-under par to clinch the championship.
And with his friend and mentor Bernhard Langer having won the US Masters twice, the Open was the only major championship yet to have been won by a German player.
"We almost have the German Grand Slam - it's only the Open missing," Kaymer joked after a final round of 69 gave him a nine-under-par total of 271.
"Winning the PGA, winning this one now, I hope it will make Bernhard proud. I'm sure it will make all Germany proud.
"To win the Masters is a huge thing and that's why I needed to adjust a few things in my swing to play better there."
