In this paper, a rectifier integrated Luneburg lens is designed at K band for wireless power transfer (WPT) applications. The lens consists of two metallic layers with a gap of 0.3 mm between them and has been made by employing the glide symmetry technique. A flare is tailored to match the outer impedance of the lens to the free space impedance. Five microstrip tapers are used at intervals of $18^{0}$ at the periphery of the lens to collect the energy from it. The rectifying circuits are co-designed and are integrated with these five tapered launchers so as to make the entire structure suitable for capturing the transmitted power from the solar power satellite wirelessly, and to convert it to the equivalent voltage. Finally, all the ports are connected with a common load for DC power combining, and the overall performance of the lens integrated rectifier as an energy harvesting system is reported in terms of its power conversion efficiency (PCE).
