Two infinite sets A and B of nonnegative integers are called additive complements if their sumset contains every nonnegative integer. In 1964, Danzer constructed infinite additive complements A and B with A(x)B(x) = (1 + o(1))x as x → ∞, where A(x) and B(x) denote the counting function of the sets A and B, respectively. In this paper we solve a problem of Chen and Fang by extending the construction of Danzer.
