摘要： Disclosed is a shaped horn in conjunction with a dielectric tube for enhanced aperture directivity that can achieve a near optimum efficiency. The shaped horn provides additional mode control to provide an improved off-axis cross-polarization response. The horn shape can be individually optimized for isolated horns or for horns in a feed array. The feed array environment can produce results that lead to a different optimized shape than the isolated horn. Lower off axis cross-polarization can result in improved efficiency and susceptibility to interference.

摘要： Methods and devices for integrating antennas fabricated using planar laminate processes. The method includes laminating one or more conductive layers to a first dielectric material layer, forming one or more holes through at least the first dielectric material layer, forming a monopole antenna through at least a first of the holes, attaching one or more integrated circuit dies to one of the conductive layer, and connecting the integrated circuit dies to the monopole antenna. The device can include a planar laminate integrated circuit module including one or more dielectric material layers, one or more integrated circuit die on a surface of or attached to the planar laminate integrated circuit module, and an integrated monopole antenna interfaced with the integrated circuit dies. The integrated monopole antenna is formed in a through hole of the planar laminate integrated circuit module, the through hole being formed through at least one of the dielectric material layers.

摘要： According to an aspect, a satellite antenna reflector includes a first surface area encompassing a first surface, where the first surface is formed to reflect a first radiated signal towards a first focal point. The reflector also includes a second surface area, encompassing a second surface, where the second surface area is formed to reflect a second radiated signal towards a second focal point. The first and second surfaces reflect the first and second radiated signals such that a first antenna gain and/or beamwidth of the reflected first radiated signal that would be received at the first focal point is the same as a second antenna gain and/or beamwidth of the reflected second radiated signal that would be received at the second focal point.

摘要： A multi-beam antenna including a reflector having a single reflector surface defining a first focal region and a second focal region. A first feed group located within the first focal region includes a first feed oriented relative to the reflector to define a first beam pointed in a first direction. The multi-beam antenna further includes a fixed attachment mechanism attaching the first feed group to the reflector such that a position of the first feed group is fixed relative to the reflector. The multi-beam antenna further includes a second feed group located within the second focal region that includes a second feed oriented relative to the reflector to define a second beam pointed in a second direction. The multi-beam antenna further includes an adjustable attachment mechanism attaching the second feed group to the reflector, whereby a difference between the first direction and the second direction is adjustable.

摘要： The monopole wire-plate antenna includes a ground plane, a roof arranged at a distance from the ground plane and at least one electrically conductive element electrically linking the ground plane to the roof. The antenna includes a supply loop arranged substantially orthogonally with respect to the ground plane, the supply loop being open such that it has two opposing longitudinal ends arranged so as to be linked to a differential connection.

摘要： Methods and systems are described for providing end-to-end beamforming. For example, end-to-end beamforming systems include end-to-end relays and ground networks to provide communications to user terminals located in user beam coverage areas. The ground segment can include geographically distributed access nodes and a central processing system. Return uplink signals, transmitted from the user terminals, have multipath induced by a plurality of receive/transmit signal paths in the end to end relay and are relayed to the ground network. The ground network, using beamformers, recovers user data streams transmitted by the user terminals from return downlink signals. The ground network, using beamformers generates forward uplink signals from appropriately weighted combinations of user data streams that, after relay by the end-end-end relay, produce forward downlink signals that combine to form user beams.

摘要： An antenna system including an antenna adjustable between a stowed configuration and a deployed configuration. The antenna includes a reflector having an annular array of spaced-apart ribs coupled to a hub, whereby the ribs can be adjustable between a collapsed configuration and an extended configuration in which the ribs outwardly extend from the hub. When the ribs dispose in the collapsed configuration, the antenna can be disposable in the stowed configuration; and when the antenna disposes in the deployed configuration, (i) the ribs can dispose in the extended configuration, and (ii) the reflector can be directionally adjustable, such as in both elevation and azimuth.
