Abstract
In one embodiment, an antenna assembly includes a reflector antenna whose aperture is covered by a radome. The radome has a principle plane corresponding to the azimuth axis of the antenna. The radome has a bulk material and a pair of absorbers made of a radio-frequency (RF)-absorbent material different from the bulk material. The pair of absorbers are arranged symmetrically along the principle plane and about the center of the radome. The pair of absorbers are located near the perimeter of the radome and are at least partially embedded in the bulk material. The pair of absorbers cover from 4%-8% of the total aperture area of the antenna.
