Abstract
A low-radar cross section antenna structure for an active electrically scanned antenna including an active electrically scanned antenna enclosure and at least two antenna elements. The antenna elements are arranged to be mounted on a front surface of the active electrically scanned antenna enclosure and embedded in a lightweight structure. The front surface and side surfaces of the active electrically scanned antenna enclosure and the antenna elements are arranged to be covered with the lightweight structure. A thin laminate is arranged to cover an outer top surface and an outer side surface of the lightweight structure. Parts of the lightweight structure are arranged to be doped with a lossy material having dielectric, magnetic and/or resistive losses, thus making these parts of the lightweight structure absorbing for electromagnetic radiation.
