Abstract: 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.

Abstract: 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.

Abstract: Disclosed is a quasi-omnidirectional antenna having three array faces, wherein each of the three array faces has a radiator array having a plurality of radiator columns. Each of the corresponding radiator columns on the radiator arrays are coupled together to a single pair of antenna ports, one per polarization. This results in a service beam having three gain lobes that can be swept in unison in a scan. By scanning the service beam, the antenna may enable a high-gain connection to a mobile device, emulating a high gain omnidirectional antenna. Further disclosed is a variation having four array faces spaced 90 degrees apart, which offers additional performance benefits.

Abstract: 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.
