The Dane enjoyed an excellent 2019 including reaching the final of the World Championships.
The rankings show just how much progress the 23-year-old has made but, speaking exclusively to Olympic Channel, Antonsen made clear that he has bigger aspirations.
"My goal is not to stop at number three. I want to reach the absolute top." - Anders Antonsen
The compatriots train together regularly with Antonsen, three years Axelsen's junior, grateful for the impact it has had on his game.
"I see Viktor as a really important piece in my development, actually, because we practise together almost every day. He's a phenomenal badminton player and he has some great, great skills.
"We both have the same goals so sometimes we are rivals. But at the same time we are also from the same nation and we practise together and try to help each other to get even better."
Poul-Erik Hoyer-Larsen remains Denmark's only badminton Olympic champion.
Antonsen will make his Games debut in Tokyo where he is determined to fighting for a medal and perhaps emulate Hoyer-Larsen.
"I have my eyes on the prize. I think my potential is there. I'm on the rise. I'm only getting better. So I'm definitely aiming for the gold medal." - Anders Antonsen
