The invention discloses a wide-angle beam scanning luneberg lens antenna and method with feed sources arranged along a straight line, and the antenna comprises a first metal plate which is in the shape of a cut circular truncated cone, and the tangent plane of the first metal plate is perpendicular to the upper and lower bottom surfaces of the circular truncated cone; the shape of the second metal plate is the same as that of the first metal plate; a cut-off surface is formed between the cut-off positions of the two metal plates; the luneberg lens is arranged between the first metal plate and the second metal plate, and the shape of the luneberg lens is matched with the shape of the upper bottom surface; the two metal nails are symmetrically arranged on the two sides of the cut surface; and the feed source of the Luneberg lens antenna is arranged on the cut-off surface and can move between the two metal nails. The wide-angle beam scanning luneberg lens with stable gain is obtained by truncating the luneberg l
