Patent number: 11978945Abstract: 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.Type: GrantFiled: November 4, 2021Date of Patent: May 7, 2024Assignee: Ubiquiti Inc.Inventors: John R. Sanford, Jude Lee, Yan Wei Sun

Patent number: 11909087Abstract: 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.Type: GrantFiled: April 21, 2020Date of Patent: February 20, 2024Assignee: Ubiquiti Inc.Inventor: John R. Sanford

Publication number: 20230418049Abstract: 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.Type: ApplicationFiled: November 17, 2021Publication date: December 28, 2023Inventors: John R.

Patent number: 10819037Abstract: 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.Type: GrantFiled: June 3, 2019Date of Patent: October 27, 2020Assignee: Ubiquiti Inc.Inventors: Gary D.
