Patent attributes
Embodiments of the present disclosure provide a cover for an antenna for electromagnetic radiation of a specific wavelength. The antenna includes an array of radiating elements, such as a plurality of horn antennas. The cover comprises a layer of cellular embossments, an upper side, and a lower side. The distance between the upper side and the lower side is approximately ¼ of the wavelength. The upper side of the layer comprises the area within an upper side of the embossments, the lower side of the layer comprises the area surrounding the embossments, and the lower side of the layer is arranged in a spaced relationship from the antenna in a radiating direction of the antenna. The antenna is mounted on a portable satellite terminal operating in the X band.
