The invention discloses a dual polarization integration plane lens antenna. The antenna which is in a layered structure is sequentially provided with a plane lens, a secondary feed source and a dual polarization primary feed source; a metal antenna support is arranged on the exterior. According to the dual polarization integration plane lens antenna which is based on a plane substrate integration waveguide structure, a substrate integration waveguide cavity antenna serves as a dual polarization feed source to perform feed on the secondary feed source, the secondary feed source and the primary feed source form into an equivalent feed source to feed the plane lens commonly, phase compensation is obtained from the lens, spherical waves are converted to be plane waves, and accordingly the antenna with high gain, high efficiency and stable pointing direction is achieved. The antenna aiming at development requirements of plane integration and a minimized long-distance wireless communication system with high gain, allows dual polarization and is low in profile, easy to integrate with a millimeter wave circuit is achieved under the Q-LINKAN application background. The dual polarization integration plane lens antenna has the advantages of being simple in design, firm in structure, compact in size and being capable of being integrated with the plane circuit.
