| Zusammenfassung: | Provided is a super-low profile high-performance dual-polarization radiation unit, which includes a radiation sheet assembly, a first feeding substrate, a second feeding substrate and a power dividingsubstrate, wherein the first feeding substrate and the second feeding substrate are orthogonally mounted on the power dividing substrate, the radiation sheet assembly is horizontally arranged above the first feeding substrate and the second feeding substrate, the radiation sheet assembly comprises a dielectric carrier and a metal radiation surface, and the metal radiation surface is provided withpairs of slots; differential coupling feeding is adopted by the first feeding substrate and the second feeding substrate to excite the metal radiation surface, front lines of each feeding structure are composed of two branches with phase inversion of 180 degrees, and the back surface of each feeding substrate is a partially copper-clad defective ground. The adoption of the above structure realizes a lambda 0/11 ultra-low |
