We demonstrate that achieving the far-field super-resolution imaging can be realized by using a planar hyperbolic metamaterial lens (PHML), beyond the Fabry-Perot resonance condition. Although the thickness of the PHML is much larger than the wavelength, the PHML not only can transmit radiative waves and evanescent waves with high transmission, but also can collect all the waves in the image region having amplitudes of the same order of magnitude. We present a design for a PHML to realize the far-field super-resolution imaging, with a distance between the sources and the images 10 times larger than the wavelength. We show that the super-resolution of our PHML is robust against losses, and the PHML can be fabricated by periodic stacking of metal and dielectric layers.
