  • Patent number: 11978945
    Abstract: Antenna assemblies are described herein. In particular, described herein are multi-focal-point antenna devices and compact radio frequency (RF) antenna devices. Any of these assemblies may include a primary feed that includes a single patterned emitting surface from which multiple different beams of RF signals are emitted corresponding to different antenna input feeds each communicating with the patterned antenna emitting surface. The antenna assembly is therefore capable of emitting beams in the same direction having different polarizations using a single primary feed.

  • Patent number: 11909087
    Abstract: Polarization-preserving microwave RF filters having multiple resonators that are each operable for different Q factors for setting overall bandwidth. A coaxial dual-polarized waveguide filter may include a cable having a hollow circular body with ends formed by copper plates that each includes at least one iris. The irises may control the energy transfer into and out of the cavity and therefore set the Q factor for the body. The shape of the internal diameter of the body and the irises may provide for reception and propagation of differently polarized signals. Multiple segments may be cascaded in series to effect higher order filtering. Also described are methods of transmitting signals using these filters.

  • Publication number: 20230418049
    Abstract: A two-layer optical beam steering device, system, method of utilization and method of fabrication are disclosed. The solid-state device enables beam steering in two dimensions with dramatically fewer control lines than prior devices. This renders the device more technically realizable, easier to control, and more affordable to manufacture. Because less data need be transferred to the device, the device is also able to operate at faster speeds.

  • Patent number: 11303016
    Abstract: Multi-directional antenna assemblies including a plurality of individual antenna sections arranged in-line with a long axis, forming a linear assembly. An antenna assembly may include a radome over the linear assembly. A linear assembly may include three or more antenna sections, each with a trough-like reflector formed by two parallel walls, and may have corrugations at the outer edges to reduce noise. An array of radiators may be positioned at the base of each antenna section. The antenna sections may share a common vertical axis and each may have a beam axes that is offset by an angle. Adjacent antenna sections may be separated by an isolation plate with a corrugated outer edge. Each antenna section may radiate greater power in a specific direction as compared to the other antenna sections.

  • Patent number: 11158933
    Abstract: A conical radiator coupled to an antenna patch disposed along a first end of the radiator, said patch disposed on an insulator. A ground plane is connected to the insulator and a radome is disposed opposite a second end of the radiator. The radome has a first region presenting a convex surface towards the radiator, and a second region presenting a concave surface towards the radiator. The first end of the conical radiator is the apex of the cone. A ground plane is included and a portion of the ground plane is a planar surface and another portion extends away from the planar portion towards the radome. Also disclosed is a method for forming a radiation pattern by shaping the radome to effectuate a predetermined radiation pattern using localized convex and concave surfaces positioned on the radome at different points in relation to the conical radiator.

  • Patent number: 10819037
    Abstract: Devices and systems, and methods of using them, for point-to-point transmission/communication of high bandwidth signals. Radio devices and systems may include a pair of reflectors (e.g., parabolic reflectors) that are adjacent to each other and configured so that one of the reflectors is dedicated for sending/transmitting information, and the adjacent reflector is dedicated for receiving information. Both reflectors may be in a fixed configuration relative to each other so that they are aligned to send/receive in parallel. In many variations the two reflectors are formed of a single housing, so that the parallel alignment is fixed, and reflectors cannot lose alignment. The device/systems may be configured to allow switching between duplexing modes. These devices/systems may be configured as wide bandwidth zero intermediate frequency radios including alignment modules for automatic alignment of in-phase and quadrature components of transmitted signals.
