Disclosed is a multiband antenna having a plurality of low band radiators, a plurality of mid band radiators, and a plurality of high band radiators. The high band radiators are disposed in a column between two adjacent low band radiators. Each of the low band radiators has a plurality of inward dipole arms and a plurality of outward dipole arms, wherein the inward dipole arms and the outward dipole arms have a different structure. The inward dipole arm structure is designed to minimize interference and shading with the high band radiators. Each of the mid band radiators has a parasitic disk with a plurality of cloaking slots.

Multi-band antenna array face and radiator configuration for mitigating interference

Disclosed is an antenna having a toroidal gradient index lens, whereby a radiator may be disposed within the inner hole of the toroid. The antenna may include a mechanism that translates the radiator along the z-axis whereby an 'upward' translation of the radiator along the z-axis tilts the antenna's elevation beam pattern downward. The radiator disposed within the hole of the toroid lens may be a dipole or a multi-sector radiator, such as a tri-sector radiator. Disclosed are two variations of the toroidal lens: a toroid shape, and a cylindrical toroidal shape.

Disclosed is a Luneberg lens that is formed of a plurality of wedge sections that can be easily assembled into a sphere. The wedge sections can be formed of an injection molded plastic, which can dramatically reduce the cost of manufacturing the lens. Different configurations of wedge sections are disclosed.

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.

Low profile telecommunications antenna

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.

Cloaking arrangement for low profile telecommunications antenna

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.

A unit cell for an antenna comprises a conductive ground plane, a low-band radiator, a pair of high-band radiators, and a conductive partition disposed along an edge intersecting a pitch axis of the conductive ground plane. The low-band radiator comprises a pair of orthogonally coupled dipoles each having a vertical stem portion and an arm portion. Each arm disposed in a plane orthogonal to the conductive ground plane. The arm portions, collectively and on-edge, produce an L-shaped radiator parallel to the conductive ground plane. Each of the high band radiators comprises a pair of cruciform radiators, each cruciform electrically connected to, spaced-apart from, and parallel to the conductive ground plane. The conductive partition isolates at least a portion of the RF energy transmitted by the low and high-band radiators.
