Abstract: A microwave antenna includes an antenna housing and a radome fabric attached to the housing, which is configured to pass microwave electromagnetic signals therethrough. The radome fabric has an opening formed therein. A vent component is attached to the radome fabric so as to cover the opening in the radome fabric when the radome fabric is viewed from an elevation view in a direction parallel to an axis extending through and perpendicular to the opening in the radome fabric. The vent component is configured to allow air to pass between the atmosphere and the antenna housing.

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.

Abstract: A radome for an antenna assembly includes a plurality of radome segments, each of the segments including a structural layer and an overlying outer layer, each of the segments further comprising a first radial side face, a second radial side face, and a perimeter section. The plurality of radome segments is assembled such that the first side face of each radome segment abuts the second side face of another radome segment to form a fully assembled radome, and the perimeter sections of the radomes together form a perimeter of the radome.
