An antenna system includes a reflector, an offset feed horn and a support platform. The reflector has a reflector surface. The reflector and offset feed horn are attached to the support platform. The offset feed horn transmits RF microwave energy toward the reflector surface. The antenna system further includes a turntable which has a single rotation axis. The turntable rotates about the antenna rotation axis. The support platform is attached to the turntable such that the turntable rotates the support platform. The reflector surface has a perturbed paraboloid geometrical shape that reflects most RF microwave energy along a beam peak pointing direction. The reflector surface reflects RF microwave energy towards the earth's surface in such a manner that the reflected RF microwave energy illuminates a narrow strip of the earth's surface from nadir to a point near the earth's horizon with substantially constant intensity. The offset feed horn is oriented and positioned such that it points away from the beam peak pointing direction.

A reflector for deflecting electromagnetic waves is provided. Said reflector comprises a resistive material along its edges in a specific pattern, wherein the resistive material has a resistance per square meter being higher than the resistance per square meter of the material of the reflector in order to attenuate and/or absorb electromagnetic energy of the electromagnetic waves.

Systems and methods for operating a deployable reflector system. The methods comprising: causing a proximal end of a first link element (LE) located at a first end of a scissoring rib assembly (SRA) to slidingly engage a hub; allowing a proximal end of a second LE of SRA to pivot relative to the hub so as to cause scissor motion of SRA while the first LE is slidingly engaging the hub; causing a distal end of a third LE located at a second end of SRA to pivot relative to the edge member during the scissor motion of SA; allowing the edge member to slidingly engage a fourth LE located at the second end of SRA during pivotal motion of the third LE; and using the edge member to cause vertical movement of a peripheral edge of a reflector relative to the hub while the edge member slidingly engages the fourth LE.

An antenna system comprises: multiple antenna elements; and multiple beam forming networks configured to produce radiation patterns for both receiving and transmission functions configured to be optimized by re-positioning said antenna elements, wherein said beam forming networks comprise a receiving beam forming network configured to combine multiple first inputs from said antenna elements into at least a first output, and a transmission beam forming network configured to divide a second input into multiple second outputs to said antenna elements.

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.

An antenna module installation system comprising a baseplate and a carrier chassis. The baseplate is configured to couple to an antenna dish assembly, and comprises an antenna module mounting apparatus including an alignment portion and a retention portion. The carrier chassis is configured to retain an antenna module, such as antenna hub amplifier, and comprises an engaging apparatus. The carrier chassis is configured to allow multiple manufacturers versions of a component to be used through adapter components. The engaging apparatus is configured to engage with the alignment portion, which positions the carrier chassis in a mounting alignment, and to move from the alignment portion to the retention portion which retains the carrier chassis in engagement with the baseplate. The engaging apparatus is designed to allow that direct connections to the component in the carrier chassis are disconnected prior to its removal.
