摘要： 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.

摘要： A telecommunications antenna comprising a plurality of unit cells each including at least one radiator which transmits RF energy within a bandwidth range which is a multiple of another radiator. The radiators are proximal to each other such that a resonant condition may be induced into the at least one radiator upon activation of the other radiator. At least one of the radiators is segmented into capacitively-connected radiator elements to suppress a resonance response therein upon activation of the other of the radiator.

摘要： 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.

摘要： 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.

摘要： Disclosed is a high performance low cost multiband antenna configuration that has a low band dipole having dipole arms formed of stamped sheet metal that has a plurality of slots. Some of the slots are oriented along a longitudinal axis of the low band dipole arm, and others are oriented orthogonal to the longitudinal axis. The presence of the slots creates a plurality of inductor structures, which act has 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.

摘要： Disclosed is a radiator assembly configured to operate in the range of 3.4-4.2 GHz. The radiator assembly comprises a folded dipole with four dipole arms that radiate in two orthogonal polarization planes, whereby the signal of each polarization orientation is radiated by two opposite radiator arms that radiate the signal 180 degrees out of phase from each other. The radiator assembly has a balun structure that includes a balun trace that conductively couples to a ground element on the same side of the balun stem plate. The combination of the shape of the folded dipole and the balun structure reduces cross polarization between the two polarization states and maintains strong phase control between the opposing radiator arms.
