QPR currently sit bottom of the table with just three points, while they have not won away from home in the league since last November.
However, the 26-year-old midfielder, who was signed from Marseille in the summer, has insisted that they can secure a result against the Gunners.
"We haven't had much luck, but it is up to us to make our own luck and once we do the results will come," he told QPR's official website.
"The lads are calm and we know if we keep improving we will start to climb the table. We can go to the Emirates with confidence, because we have a good team with a good, strong mentality.
"We have experience and at places like the Emirates, you need to be strong, composed and confident."
Mbia has 40 Cameroonian caps to his name.
