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 telecommunications antenna having a plurality of cloaked low band (LB) and high band (HB) dipoles. The LB and HB dipoles provide cloaking by breaking the dipoles into dipole segments, and providing conductive cloaking elements over the gaps between dipole segments to form a plurality of capacitors along the dipole. The capacitors along the LB dipoles provide a low impedance to LB RF signals and a high impedance to HB signals. The capacitors formed on the HB dipoles provide a low impedance to RF signals and high impedance to harmonics of the LB RF signals. This cross-cloaking of dipoles enables more dense arrangements of LB and HB dipoles on an antenna array face, providing opportunities to arrange, for example, the LB dipoles with an array factor that results in an advantageous fast roll off gain pattern.

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: A lowband radiator has four dipole arms and a central region that is centered at the intersection of the dipole arms. Each of the dipole arms has a sequence of capacitive and inductive structures and a pair of high gain wings that are disposed in the dipole central region. In one embodiment of the lowband radiator, each dipole arm has a gap within the central region that is colinear with the dipole arm. The dipoles provide for improved isolation from nearby midband radiators while providing high gain.

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 multiband antenna has a plurality of first, unit cells and second unit cells. Each first unit cell has two high band radiator clusters and two low band radiators disposed approximately in the center of each of the high band radiator clusters. Each second unit cell has two high band radiator clusters and one low band radiator that is disposed between the two high band radiator clusters. The first unit cell is designed for a superior low band gain pattern, and the second unit cell is designed for a superior high band gain pattern. By selectively arranging the first and second unit cells in a specific heterogeneous pattern, the characteristics of the two unit cells may advantageously and constructively combine to form a high performance antenna gain pattern that is consistent across the low band and high band.

摘要: An omni-directional antenna including a plurality of stacked omni-directional antenna core assemblies. Each antenna core assembly comprises a conductive ground plane defining an axis normal to the ground plane and a plurality of conductive plates projecting orthogonally from the conductive ground plane and angularly spaced about the axis. Each of the plates defines an edge extending radially outboard from the central axis and diverging away from the conductive ground plane as the radial distance increases from the central axis. The edge defines a first region defining an acute angle relative to the conductive ground plane and a second region, radially outboard of the first region defining an arcuate shape.
