The Australian, 19, caused arguably the surprise of the tournament so far when he defeated the world number one in the fourth round.
"I was in a bit of a zone out there and didn't really notice the crowd," Kyrgios told BBC Sport. "I was struggling a little on return but I worked my way into it and I served really well throughout, so am very happy.
"You have to believe that you can win the match from the start and I definitely did. I am playing really well on grass."
Kyrgios, ranked 144th in the world, returns to action today when he faces Milos Raonic in the quarter-finals.
