摘要：
Recently, early superinflation driven by the phantom field has been proposed and studied. The detection of primordial gravitational waves is an important means to know the state of the very early universe. In this brief report we discuss in detail the gravitational wave background excited during the phantom superinflation, compared with that of the usual inflation model.
