QUICK CONNECT WAVEGUIDE ADAPTER
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.
FEED FOR DUAL BAND ANTENNA

DIELECTRIC DISH ANTENNA SYSTEM AND METHODS FOR USE THEREWITH
In accordance with one or more embodiments, a method includes receiving a first wireless signal via a feed point on an antenna body, wherein the antenna body includes a dielectric core having a reflective surface configured as a dish reflector; reflecting the first wireless signal via the reflective surface to an aperture of the antenna body; and radiating the first wireless signal from the aperture.
Antenna assembly for long-range high-speed wireless communications
Various embodiments of antenna assemblies are disclosed herein. In one embodiment, the antenna assembly includes a reflector comprising a center opening, a feed-antenna subassembly situated in front of the reflector, a rear housing situated behind the reflector, and a pole-mounting bracket comprising a base plate situated between the reflector and the rear housing. The feed-antenna subassembly comprises a feed tube that houses at least one of: a transmitter circuit and a receiver circuit. The rear housing is coupled to a front side of the reflector via the center opening. The rear housing comprises a center cavity, and a back end of the feed tube is inserted in and coupled to the center cavity. The base plate is coupled to the reflector and the rear housing in such a way that decoupling between the base plate and the reflector requires a prior decoupling between the feed-antenna subassembly and the rear housing and a prior decoupling between the rear housing and the reflector.
Folded optics mesh hoop column deployable reflector system
Folded optics reflector system includes a hoop assembly configured to expand between a collapsed configuration and an expanded configuration to define a circumferential hoop. A mesh reflector surface is secured to the hoop assembly such that when the hoop assembly is in the expanded configuration, the reflector surface is expanded to a shape that is configured to concentrate RF energy in a desired pattern. The system also includes a mast assembly comprised of an extendible boom. The hoop assembly is secured by a plurality of cords relative to a top and bottom portion of the boom, whereby upon extension of the boom to a deployed condition, the hoop assembly is supported by the boom. A subreflector is disposed at the top portion of the boom.
Subreflector of a dual-reflector antenna
A subreflector of a dual-reflector antenna comprises a first extremity comprising a convex inner surface, a second extremity adapted for coupling to the extremity of a waveguide, and a body extending between the first extremity and the second extremity. The body comprises a first dielectric part having a portion penetrating into the waveguide and a portion outside the waveguide, and a second metallic part comprising a first cylindrical portion, contiguous with the first extremity of the subreflector, whose diameter is greater than the portion outside the waveguide of the first dielectric part, and a second cylindrical portion, adjacent to the first cylindrical portion, extended by a conical portion that penetrates into the first dielectric part.
