Orthogonal polarization broadband wide-angle scanning phased array antenna

The invention discloses an orthogonal polarization broadband wide-angle scanning phased-array antenna. The orthogonal polarization broadband wide-angle scanning phased-array antenna comprises a metal floor, a frequency selective absorption surface, a plurality of metal slot radiation sheets, a plurality of coaxial cables and a plurality of resistive surfaces, the first ends of the plurality of metal slot radiation sheets are vertically arranged on the metal floor, and the second ends of the plurality of metal slot radiation sheets are vertical to the frequency selective absorption surface; the plurality of resistive surfaces are respectively arranged at the joints of the metal slot radiation sheets, and the plurality of coaxial cables are respectively arranged in the corresponding metal slot radiation sheets. Aiming at the problems that a broadband orthogonal polarization phased-array antenna is large in wide-angle scanning active standing wave and has a scanning blind area, a frequency selective absorption s
