  • Base station antennas with lenses for reducing upwardly-directed radiation
    Patent number: 10587034
    Abstract: A base station antenna includes a radiating element that extends forwardly from a backplane and that is configured to transmit and receive signals in the 5.15-5.25 GHz frequency band and a radio frequency lens that is mounted forwardly of the radiating element. The RF lens is configured to re-direct a portion of an RF signal emitted by the radiating element downwardly so that a first peak emission of RF energy through a combination of the radiating element and the RF lens at elevation angles that are greater than 30° from a boresight pointing direction of the radiating element is less than a second peak emission of RF energy through the combination of the radiating element and the RF lens at elevation angles that are less than ?30° from the boresight pointing direction of the radiating element.
