In this paper, leveraging the resonant phase and the geometry phase simultaneously, we demonstrated a low scattering lens antenna, which can work at both transmission and reflection mode. Different from the traditional microwave lens which only realizes wavefront shaping in half-space, the proposed metasurface lens not only squeezes the transmitted divergent beam to improve the gain of the conventional circular-polarized antenna, but also scatters the electromagnetic wave to maintain a low reflection property in broadband. The proposed lens antenna working in full space may provide a new approach for an integrated communication system.
