The Frenchman was unhappy with the winger's conduct as his side bowed out of the Champions League.
Bayern beat the Gunners 3-1 on aggregate to progress to the Champions League quarterfinals following a 1-1 draw on Tuesday night, with Robben at the heart of the action.
The former Chelsea man saw his first appeal for a penalty waved away after he beat Santi Cazorla in the area and then tumbled to the ground, but he was later successful when brought down by Laurent Koscileny in the dying minutes.
And Wenger has taken the opportunity to lay into the Dutchman, who also won a spot-kick in the first leg when felled by goalkeeper Wojciech Szczesny.
"Robben is very good at getting the maximum out of nothing," he told ITV Sport. "He is a great player, but also a good diver. He dived well [in first leg] and he dived well again tonight.
"He is one of the best players in the world but he gets past the player [Cazorla], then he actually slows down, looking for the foul."
Alex Oxlade-Chamberlain was impressive for the Gunners in Munich, but says his side lacked the cutting edge to get three unanswered goals it needed to progress.
"Maybe we lacked a bit of quality with our final ball," he also told ITV Sport. "We got into a lot of dangerous positions but we just lacked that final cutting edge ball.
"At the top level you need to be able to do that, especially against a team like Bayern, and maybe tonight we were just lacking that, but I think the boys put in a great shift tonight and we can take away positives and be proud of our efforts."
