The invention discloses a planar feed-source transceiving integrated crescent lens antenna comprising a crescent lens, a lens extending layer, a lens support, a pedestal, a receiving feed-source antenna array, and a transmitting feed-source antenna array. The crescent lens, the lens extending layer and the lens support are formed by media; the lens support is a hollow cylinder; and the pedestal is a cylinder. The receiving feed-source antenna array and the transmitting feed-source antenna array are arranged on the upper surface of the pedestal; and a one-dimensional scanning or two-dimensional scanning array is formed according to an arrangement mode of the receiving feed-source antenna array and the transmitting feed-source antenna array. Each of the receiving feed-source antenna array and the transmitting feed-source antenna array includes a plurality of microstrip antennas. The antenna has advantages of capability of transmitting and receiving antenna integration, high design freedom, high aperture efficiency, low sidelobe, high directivity, light weight, and capability of integration with a planar circuit.
