ABSTRACT:
A waveguide includes a first waveguide member and a second waveguide member. The second waveguide member is combined with the first waveguide member to form a through hole. The first waveguide member includes a first shell and two first wing portions connected to the first shell, and the two first wing portions form a first plane. The second waveguide member includes a second shell and two second wing portions connected to the second shell, and the two second wing portions form a second plane. Bulged strips are formed at the inner rims of the second plane neighboring the through hole and extend along a longitudinal direction of the through hole, and the bulged strips protrude the second plane.
