Abstract
A waveguide structure for a compact and scalable dual-polarized antenna array. In one example, a waveguide device comprises septum polarizers dividing common waveguides into first waveguides associated with a first polarization and second waveguides associated with a second polarization. The sets of septum polarizers may be inverted relative to each other to form first groups of four adjacent first waveguides for each type of waveguide. The waveguide device may also include a waveguide feed network including a first waveguide feed stage including waveguide combiner/dividers coupled between the four adjacent waveguides intermediate waveguides. The waveguide device may further include a second waveguide feed stage coupled with the first intermediate waveguides and the second intermediate waveguides, wherein the second waveguide feed stage extends in a direction perpendicular to the first waveguide feed stage.
