The provided is a germanium telluride-based reflectarray element and millimeter-wave frequency-reconfigurable reflectarray antenna. The reflectarray antenna includes a plurality of reflectarray elements, a dielectric substrate, a metal ground, and a feed source, where the reflectarray element is located on an upper surface of the dielectric substrate, and includes a loop body and two phase delay lines; two first germanium telluride films are embedded in the loop body to divide the loop body into two parts with equal lengths; each part of the loop body is connected to a middle portion of one phase delay line; two second germanium telluride films are embedded in the phase delay line; the two second germanium telluride films are symmetrically distributed up and down with the middle portion of the phase delay line as a center.
