We consider the planar equation \(\dot{z}=\sum a_{k, l}(t) z^{k} \bar{z}^{l}\), where \(a_{k, l}\) is a \(T\)-periodic complex-valued continuous function, equal to 0 for almost all \(k, l \in \mathbb{N}\). We present sufficient conditions imposed on \(a_{k,}\), which guarantee the existence of its \
