  • Publication number: 20250046992
    Abstract: A multi-band antenna has a first tilt section and a second tilt section. The first tilt section has a first tilted reflector on which is disposed a first plurality of radiators configured to radiate in a low band, and a first flat reflector on which is disposed a second plurality configured to radiate in a mid band; and a second tilt section having a second tilted reflector on which is disposed a third plurality of radiators configured to radiate in a low band, and a second flat reflector on which is disposed a fourth plurality configured to radiate in a mid band, the second tilted reflector being tilted at a second tilt angle. The antenna has a conformal radome that has sloped surfaces that substantially match the tilt of the first and second tilted reflectors.

  • Publication number: 20250047012
    Abstract: An antenna has a plurality of columns of C-Band radiators whereby each of the columns of C-Band radiators is supported by a single multilayer feedboard. The multilayer feedboard has a first signal layer disposed on an upper surface; a first ground layer; a second signal layer, and a second ground layer disposed on a lower surface. The solder joints for the coupling the RF signal cable outer conductors, and all of the solder joints for coupling the signals to the ?45 and +45 dipoles to each of the C-Band radiators, are disposed on the second ground layer for ease of manufacture.

  • Publication number: 20240380104
    Abstract: Disclosed is a radome for a cellular antenna that significantly improves windloading, which may be crucial for successful deployments on cell towers where the antenna may be deployed at considerable height and in environments where extreme weather is possible. The windloading performance is provided by the profile shape of the radome. The profile shape may be accommodated through the use of low band dipoles that are shorter in length.

  • Patent number: 11721891
    Abstract: A sector antenna is provided comprising a base plate, a cable tower mounting to the base plate and at least one reflector mounting to the base plate and substantially parallel to the axis of the cable tower. The reflector includes a plurality of electrical components operative to transmit and receive telecommunications signals in an arcuate sector of the antenna. The reflector has an inwardly facing surface opposing the cable tower and an outwardly facing surface disposed away from the cable tower. Furthermore, a cable guide plate is interposed between the cable tower and the reflector such that apertures formed in the cable guide plate may provide a guide through which a conductor may pass for making an electrical connection to one of the electrical components along the outwardly-facing surface of the reflector. The cable guide plate apertures align with the reflector apertures and provide a guide to operators when assembling, maintaining and repairing the telecommunications antenna.
