Patent attributes
A base station antenna includes a column of radiating elements comprising first and second sets of radiating elements, each radiating element being configured to operate in a first frequency band that has first and second sub-bands. The second set of radiating elements is located above and/or below the first set of radiating elements. The antenna further includes a feeding assembly that is configured to feed first RF signals that are in the first sub-band and second RF signals that are in the second sub-band to the column of radiating elements, where the feeding assembly is configured to partially attenuate sub-components of the second RF signals that are fed to the second set of radiating elements more than sub-components of the first RF signals that are fed to the second set of radiating elements.
