ABSTRACT:
A generally rectangular waveguide antenna has two narrow side walls connected to two broad walls. One of the broad walls takes the form of a conventional rectangular ridged wall. The other broad wall is curved with the arc of the curve extending substantially the full width of the wall. The antenna has an open end and a closed end. The end of the curved broad wall extends beyond the end of the rectangular ridge wall at the open end of the antenna. The two narrow sidewalls are cut at an angle, at the open end, to join the shorter ridged wall and the extended curved wall.
