  • Publication number: 20210029556
    Abstract: A twin beam base station antenna includes a first array that has a plurality of columns of first frequency band radiating elements, the first array configured to form a first antenna beam that provides coverage throughout a first sub-sector of a three-sector base station. The radiating elements in a first of the columns in the first array have a first azimuth boresight pointing direction and the radiating elements in a second of the columns in the first array have a second azimuth boresight pointing direction that is offset from the first azimuth boresight pointing direction by at least 10°. The radiating elements in the second of the columns in the first array are electrically steered.

  • Publication number: 20210021019
    Abstract: Base station antennas are provided herein. A base station antenna includes a multiband beam-former array having a plurality of vertical columns of radiating elements. In some embodiments, at least two of the vertical columns are commonly fed for a first frequency band of the multiband beam-former array that is lower than a second frequency band of the multiband beam-former array. Related methods of operation are also provided.

  • Patent number: 10601120
    Abstract: A base station antenna includes a reflector assembly and a linear array of radiating elements extending forwardly from the reflector assembly. The reflector assembly includes an RF choke that has a choke body and a choke cover. The choke cover at least partially covers a choke body opening so that a choke opening of the RF choke is smaller than the choke body opening.

  • Publication number: 20180227775
    Abstract: A base station antenna includes a first set of radiating elements that are configured to generate a first antenna beam that has a first peanut-shaped antenna pattern in an azimuth plane and a second set of radiating elements that are configured to generate a second antenna beam that has a second peanut-shaped antenna pattern in the azimuth plane. A longitudinal axis of the first peanut-shaped antenna pattern in the azimuth plane is rotated approximately ninety degrees from a longitudinal axis of the second peanut-shaped antenna pattern in the azimuth plane.

  • Patent number: 7688271
    Abstract: A dipole antenna comprising a base; first and second pairs of dipoles positioned in front of the base and arranged around a central region; a first feed line which extends from the base towards the dipoles and splits at a first junction positioned in front of the base into a first pair of feed probes each of which is coupled to a respective one of the first pair of dipoles; and a second feed line which extends from the base towards the dipoles and splits at a second junction positioned in front of the base into a second pair of feed probes each of which is coupled to a respective one of the second pair of dipoles. The feed probes are spaced from the dipoles so as to field-couple with the dipoles. In one embodiment, the first pair of feed probes is positioned on a first side of the dipoles and the second pair of feed probes is positioned on a second side of the dipoles opposite to the first side. In another embodiment, the dipoles are printed on a PCB.

  • Patent number: 7196674
    Abstract: A dual polarized three-sector base station antenna with variable beam tilt in each sector. The invention advantageously provides a variable phase shifter with very small lateral dimensions which significantly reduces the diameter of a three-sector antenna. The feed network is located on both sides of the antenna ground plane, and the combination of the cable, microstrip and airstrip lines further reduces the lateral size of the antenna. Metal rings on the radome and double-bended ground plane are providing antenna with better cross-polarization and port-to-port isolation.
