Consider this a stack of waveguides glued together, each with one common wall. The "leaky" part is at the ends of the waveguides, which are not completely shorted. There is a wall to cover the center portion of the stick ends, but the left and right edges are left open, creating a magnetic field that interacts and deforms the sidelobes.
The antenna is designed for 9.4 GHz and used for weather radar in aircraft. You want a narrow beam pattern in both azimuth and elevation in order to analyze the weather cell. Unlike a ships radar that has narrow azimuth, but all elevations. Bendix made these antennas in quantity in the late 70's.
