  • Patent number: 12132258
    Abstract: Disclosed is a decoupling dipole structure that renders a midband dipole effectively transparent to a nearby lowband dipole. This not only improves the beam quality in the lowband without sacrificing beam quality in the midband, it also enables different lowband dipoles to be employed to customize the lowband performance of the multiband antenna without requiring a redesign of the midband dipoles or of the array face.

  • Publication number: 20240339757
    Abstract: Disclosed is a midband dipole for use in a multiband antenna. The midband dipole has four folded dipoles, each of which is coupled to a decoupling circuit that has two capacitance points. The disclosed decoupling circuit configuration mitigates common mode resonance with nearby lowband dipoles, further preventing cross polarization in the midband.

  • Publication number: 20240266758
    Abstract: Disclosed is a high performance low cost multiband antenna configuration that has a low band dipole having dipole arms formed of stamped sheet metal with a plurality of inductor structures. The plurality of inductor structures are oriented along a longitudinal axis of the low band dipole arm, and others are oriented orthogonal to the longitudinal axis. The plurality of the inductor structures act as cloaking structures that make the low band dipole substantially transparent to high band RF energy without inhibiting the performance of the dipole in the low band.

  • Patent number: 11522289
    Abstract: Disclosed is an antenna that enables dense packing of low band, mid band, and C-band radiators. The low band radiators have a plurality of dipole arms that minimize re-radiation of either RF energy emitted by either the mid band or C-Band radiators. In one embodiment, the dipole arms are formed of a two-dimensional structure that has a shape that substantially prevents re-radiation in both the mid band and the C-band. In another embodiment, the dipole arms have two different configurations: a first configuration optimized for preventing re-radiation in the mid band, and a second configuration optimized for preventing re-radiation in the C-Band. In the latter embodiment, the low band radiators in close proximity to the mid band radiators have dipole arms of the first configuration, and the low band radiators in close proximity to the C-Band radiators have dipole arms of the second configuration.
