    摘要: A multiple feed antenna includes a first waveguide having a first upper aperture with a first wall surrounding the first upper aperture; a second waveguide disposed in parallel to the first waveguide, in which the second waveguide has a second upper aperture; a second wall surrounding the first wall, with a first groove between the second wall and the first wall; a third wall surrounding the second wall and the second upper aperture, with a second groove between the third wall and the second wall; a fourth wall surrounding the third wall, with a third groove between the fourth wall and the third wall; and a plurality of ribs connecting the first wall and the second wall.
