The invention discloses a wide-angle scanning low cross polarization antenna array and radio frequency communication equipment, the antenna array comprises N * M antenna units, a first group of metal walls, a second group of metal walls, a third group of metal walls and a metal ground, each antenna unit comprises a radiation structure and a feed structure, and the feed structure feeds the radiation structure; the first group of metal walls surrounds the periphery of the radiation structure, and the first group of metal walls is electrically connected with the metal ground to form a back cavity structure; the second group of metal walls are arranged on two sides of the first group of metal walls; the third group of metal walls is arranged right above the first group of metal walls, and the third group of metal walls and the first group of metal walls form a double-layer back cavity structure. According to the invention, the three groups of metal walls are combined to form a radiation structure, so that on one
