Kittel's free energy expression with the cross term of two sublattice polarizations was dealt with to obtain some properties of a linear antiferroelectric. Four phases, nonpolar, polar, antipolar and semipolar, are stable in proper ranges of temperature and bias field. The phase diagram was obtained by comparisons of free energy of four phases. The isothermal relation between the polarization and the external field predicted successive forced transitions and a multiple hysteresis loop. At a constant field, the antipolar-polar-semipolar-nonpolar transitions were expected at changing temperature. Correspondingly to the transition scheme, complicated behaviors of polarization, antipolarization and susceptibility as functions of temperature were calculated with bias field as a parameter.
