摘要： 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.

摘要： A microwave system and method comprising a center fed parabolic reflector; a radio transceiver, said transceiver disposed on a circuit board and coupled to a radiator, said radiator disposed on the circuit board and extending orthogonally from a surface of the circuit board. Embodiments also include directors on the circuit board and a sub-reflector comprising a thin plate disposed on a weather proof cover and said sub-reflector having a substantially concave surface with a focus directed towards the radiator. The circuit board may be physically integrated within the feed mechanism of the center fed parabolic reflector and the radio transceiver is configured to provide OSI layer support.

摘要： 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.

摘要： 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.

摘要： Multi-directional antenna apparatuses, which may include phased array antennas and/or arrays of multiple antennas, and methods for operating these directional antennas. In particular, described herein are apparatuses configured to operate as an access point (AP) for communicating with one or more station devices by assigning a particular directional beam to each access point, and communicating with each station device using the assigned directional beam at least part of the time. Methods and apparatuses configured to optimize the assignment of one or more directional beam and for communicating between different station devices using assigned directional beams are described. Also described are methods of connecting a radio device to an antenna by connecting a USB connector on the radio device to a USB connector on an antenna and identifying the antenna based on a voltage of the ground pin on the antenna's USB connector.

摘要： 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.
