Example embodiments relate to low elevation side lobe antennas with fan-shaped beams. An example radar unit may include a radiating plate having a first side and a second side with an illuminator, a waveguide horn, a waveguide opening, and a radiating sleeve extending into the first side of the radiating plate. The waveguide opening is positioned on the first end of the first side and the radiating sleeve is positioned on the second end of the first side. The radar unit also includes a metallic cover coupled to the first side of the radiating plate such that the metallic cover and the radiating plate form waveguide structures. The waveguide horn is configured to receive, from an external source, electromagnetic energy provided through the waveguide opening via a first waveguide and provide a portion of the electromagnetic energy to the illuminator via a second waveguide such that the portion of the electromagnetic energy radiates off the illuminator and through the radiating sleeve into an environment of the radar unit as one or more radar signals.

An article, integrated device, apparatus and a method for mounting a satellite antenna feed structure to an antenna reflector unit. The device comprises, in combination, a housing associated with the feed structure and a cup mounted to the antenna reflector unit. The housing includes a plurality of members projecting radially therefrom, the members being arranged and configured for cooperative engagement with slots correspondingly arranged and configured in the cup, a resilient gasket lining at least a bottom interior surface of the cup. Alternatively, the cup includes a plurality of inwardly projecting members arranged and configured for cooperative engagement with slots correspondingly arranged and configured in the housing. Upon positioning the housing axially relative to, and in mating engagement with, the cup, engaging the members with and sliding them into receiving ports of the slots, rotating the housing such that the members engage with and slide along the slots, and thereby biasing a mating portion of the housing against the gasket lining, the housing is engaged firmly within the cup.

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.
