We first study the spectrum of Hermitian adjacency matrix (H-spectrum) of Cayley digraphs X(D2n,S) on dihedral group D2n with ｜S｜ =3.Then we show that all Cayley digraphs X(D2p,S) with ｜S｜ =3 and p odd prime are Cay-DS,namely,for any Cayley digraph X(D2p,T),X(D2p,T) and X(D2p,S) having the same H-spectrum implies that they are isomorphic.
