description The invention discloses a wideband microwave antenna feed comprising a metal subreflecting surface, a medium block and a circular waveguide pipe, wherein the metal subreflecting surface is connected with the circular waveguide pipe by the medium block; the metal subreflecting surface, the medium block and the circular waveguide pipe are symmetrical corresponding to the same axial line, the top of the medium block is provided with a coaxial annular groove and a conical groove, and the corresponding position of the bottom of the metal subreflecting surface and the conical groove is provided with a matching taper. Because the structures of the medium block and the metal subreflecting surface are moulded, the upper part of the medium block is provided with the conical groove and at least one annular groove, and the bottom pf the metal subreflecting surface is provided with the matching taper corresponding to the conical groove in order to increase a variable factor of the feed; when passing through a circular ste
