Zusammenfassung:A lensed base station antenna includes a first array that includes a plurality of radiating elements that are configured to transmit respective sub-components of a first RF signal, a second array that includes a plurality of radiating elements that are configured to transmit respective sub-components of a second RF signal and a skeletal RF lens positioned to receive electromagnetic radiation from a first of the radiating elements of the first array and from a first of the radiating elements of the second array. In some embodiments, the skeletal RF lens includes a plurality of layers of dielectric material that are separated by air gaps.
