Abstract : The theoretical behavior of a rectangular beam waveguide antenna with an aperture of closely spaced holes was investigated. Measurements on such an antenna with the antenna cavity excited in the n=0 mode agree quite well with predicted values. The theoretical radiation pattern and gain of a rectangular beam waveguide antenna excited in the n=1 mode were derived. Preliminary measurements indicate that this mode of excitation may result in a useful form of antenna. (Author)
