Wiley conceded that Robin van Persie, who had already scored twice for the Gunners, should have been awarded a late spot-kick when he appeared poised to tap in winner from close range, but was shoved to the ground by Kyle Naughton.
Wenger said: "Here the whole season we have got zero penalties [in fact they have been awarded three in the Premier League this season]. It is absolutely amazing, because you see other clubs who have got 10. I don't know (why the penalty was not given), we have to accept the decision of the referee."
However, Norwich boss Paul Lambert also thought his team had a "stonewall penalty" in the first-half.
"It is a stonewall penalty, the one on Russell Martin," said Lambert. "My player had his shirt pulled. No doubt Arsenal will moan about the one they didn’t get but if you look at it, Gervinho is offside so I think they might be clutching at straws with that one."
