摘要： A shield for shielding radio frequency emissions being emitted from a communications antenna. The shield has a first layer of material having the physical property of generally absorbing radio frequency electromagnetic emissions and a second layer of material having the physical property of generally reflecting radio frequency emissions. The first layer of material is positioned between the second layer of material and the communications antenna. Therefore, the first layer of material absorbs a portion of the radio frequency emissions from the communications antenna, and the second layer of material reflects back the remaining emissions to the first layer of material. Therefore, the first layer absorbs a further portion of the remaining emissions. A layer of absorbing material is placed between the combined first & second layers and a material that is transparent to radio frequency emissions and through which the communications antenna radiates radio frequency energy. The purpose of the absorbing material between the transparent material and the combined first & second layers is to minimize escape of radio frequency energy along the transparent material. The radio frequency energy could otherwise escaped around the barrier of the first & second layers due to reflection and refraction of radio frequency energy within the body of the transparent material.
