Radio system for long-range high-speed wireless communication
One embodiment of the present invention provides a radio assembly. The radio assembly includes an antenna housing unit that houses a pair of reflectors which are situated on a front side of the antenna housing unit, a printed circuit board (PCB) that includes at least a transmitter and a receiver, and a backside cover. The PCB is situated within a cavity at a backside of the antenna housing unit and the backside cover covers the cavity, thereby enclosing the PCB within the antenna housing unit. One embodiment of the present invention provides a user interface for configuring a radio. The user interface includes a display and a number of selectable tabs presented on the display. A selection of a respective tab results in a number of user-editable fields being displayed, thereby facilitating a user in configuring and monitoring operations of the radio.

A waveguide connector assembly includes a waveguide connector having a first end, a second end opposite the first end, and a body having a length that extends axially between the first end and the second end. The body has an interior surface and an exterior surface, the waveguide connector being configured to receive a waveguide at the first end. The waveguide connector assembly further includes a movable sleeve having a first end, a second end opposite the first end, a body extending axially between the first end and the second end, and an actuating surface. The movable sleeve is configured to slide axially along the exterior surface of the waveguide connector, the actuating surface being configured to prevent axial movement of the waveguide when the movable sleeve is in an actuating position.

The present invention discloses an antenna for satellite communication having a structure for switching multiband signals. The antenna for satellite communication according to an embodiment of the present invention includes a main reflecting plate configured to be rotatable in a predetermined direction so as to be oriented in a direction in which a satellite is located, a first feed horn configured to be detachably installed in a region of an edge of the main reflecting plate, a sub-reflecting plate configured to be installed so as to be spaced apart from a reflecting surface of the main reflecting plate by a predetermined distance by at least one support means provided in a region of the main reflecting plate, and a second feed horn configured to be detachably installed on a side opposite to the reflecting surface of the sub-reflecting plate, wherein an installation position of the sub-reflecting plate is changeable.
ANTENNA AND METHOD
We generally describe an antenna, in particular a parabolic antenna, comprising: a primary reflector, in particular a parabolic dish, a feed antenna and/or a secondary reflector for transmitting and/or reflecting an electromagnetic wave towards the primary reflector and/or receiving a said electromagnetic wave reflected from the primary reflector, a feed coupled to the feed antenna and/or secondary reflector, wherein the feed antenna and/or secondary reflector is coupleable, via the feed, to a radio-frequency transmission and/or reception device, and an actuator unit coupled to one or more of the feed antenna, the secondary reflector and the feed, wherein the actuator unit is configured to move the feed antenna and/or the secondary reflector, by exerting a mechanical force on the feed antenna and/or the secondary reflector and/or the feed, relative to the primary reflector.
HIGH-DIRECTIVITY BROADBAND SIMULTANEOUS TRANSMIT AND RECEIVE (STAR) ANTENNA AND SYSTEM
In various implementations, a quasi-monostatic STAR antenna system comprises a parabolic reflector antenna for transmission (TX) and a receiving (RX) antenna mounted back-to-back with the reflector feed. The physical size of the RX antenna can be comparable to or smaller than that of the TX feed, in order to prevent additional reflector blockage. To increase the system isolation both the TX feed and the RX antenna are CP. In one implementation, for example, to achieve same TX and RX polarization (i.e. no polarization multiplexing) the TX feed is LHCP and the RX antenna is RHCP. The LHCP fields from the TX feed undergo polarization reversal after bouncing back from the reflector. Thereby, the TX and RX operate in the same polarization, as illustrated in FIG. 1. This approach can also support simultaneous dual polarized operation if appropriate feed and RX antenna are used
Rotary joint for a rotary antenna and rotary antenna comprising such a joint
A rotary joint including a stator intended to be fastened on a first part of the antenna and defining a transmission surface, and a rotor intended to be fastened on a second part of the antenna and defining a transmission surface, wherein one of the transmission surfaces includes primary means for delimiting electromagnetic signals and the other includes complementary means for delimiting electromagnetic signals; the rotor being mounted rotating relative to the stator such that at least part of the transmission surface of the rotor is positioned across from at least part of the transmission surface of the stator, the facing parts forming at least one transmission path between them for the electromagnetic signals delimited by the primary and complementary delimiting means.
Higher Signal Isolation Solutions for Printed Circuit Board Mounted Antenna and Waveguide Interface
Higher isolation solutions for printed circuit board mounted antenna and waveguide interfaces are provided herein. An example waveguide mounted onto a dielectric substrate can enclose around a periphery of an antenna and contain radiation produced by the antenna along a path that is coaxial with a centerline of the waveguide. The waveguide can have a first portion having a first cross sectional area that is substantially polygonal that transitions to a second cross sectional area that is substantially conical. A shape of the radiation produced by the antenna is altered by the first portion as the radiation propagates through the first portion. A second portion includes an elongated tubular member coupled with the first portion

Compact radio frequency antenna apparatuses
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. Also described herein are compact RF antenna devices having a lightpipe that passes through the single patterned emitting surface.
Sub-reflector assembly with extended dielectric radiator
In one embodiment, a sub-reflector assembly for a reflector antenna has (i) a waveguide transition at a waveguide end of the sub-reflector assembly and configured to fit within a waveguide, (ii) a dielectric radiator connected to the waveguide transition and extending both laterally and back towards the waveguide end of the sub-reflector assembly, and (iii) a sub-reflector connected to the dielectric radiator. By configuring the dielectric radiator to extend both laterally and back towards the dielectric end of the assembly, radiated energy from the waveguide is directed such that the sub-reflector assembly can be used with shallow reflector dishes (e.g., F/D ratio greater than 0.25) and still achieve sufficiently high directivity.
