Open the CIPO recordAbstract From the Canadian patent
An array of horn antennas with non-uniform aperture sizes is disclosed wherein the individual horns phase track over a wide frequency band. The horn with the smallest aperture is considered the reference horn and, its length defines the overall horn length of the other horn in the array. The flare lengths of the other horns of the array are less than the length of the reference horn, and lengths of waveguide are added to the other horns such that the respective combined flare lengths and waveguide lengths of each of the other horns equals the horn length of the reference horn. The respective lengths of the flare and the waveguide section are chosen such that the resultant horn antenna phase …
