摘要： An antenna array that can include a plurality of antenna cells positioned in a global coordinate system of the antenna array. Each of the plurality of antenna cells has a respective local coordinate system and can include a radiating element having a predetermined angle of rotation defined in the global coordinate system and an antenna port coupled to the radiating element, the antenna port being positioned at a particular set of coordinates in the respective local coordinate system. The particular set of coordinates of the antenna port of each of the plurality of antenna cells can be the same.

摘要： 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.

摘要： The described features include a scalable waveguide architecture for a waveguide device. The waveguide device may be split into one or more waveguide blocks instead of manufacturing increasingly larger single-piece waveguide devices. Described techniques provide for a radio-frequency (RF) seal between such waveguide blocks that may facilitate greater manufacturing tolerances while maintaining an effective RF seal at the junction of the waveguide blocks. The described techniques include channels within one or more waveguide blocks opening to the dielectric gap between the waveguide blocks. The channels may, for each of multiple waveguides joined at the interface between waveguide blocks, be included in one or both waveguide blocks and may be in a single waveguide dimension relative to the multiple waveguides, or extend for more than one waveguide dimensions.
