We consider the oscillating dark energy with periodic equation of state in two equivalent formulations: ideal fluid or scalar-tensor theory. It is shown that such dark energy suggests the natural way for the unification of early-time inflation with late-time acceleration. We demonstrate how it describes the transition from deceleration to acceleration or from non-phantom to phantom era and how it solves the coincidence problem. The occurence of finite-time future singularity for the oscillating (phantom) universe is also investigated.

    Choosing the Lorentz-violating tensor with spatial components Bii = -3B00 makes the quadratic kinetic term Lorentz invariant, giving the phantom excitation the dispersion omega^2 = k^2 for any background.
