A communication system including a plurality of horn antennas, a waveguide feed network, and a converter unit coupled to the plurality of horn antennas is disclosed. The waveguide feed network is coupled to each horn antenna, splits an information signal into a first component signal having a first polarization and a second component signal having a second polarization and provides a first summed component signal at a first feed port and a second summed component signal at a second feed port. The converter unit receives the first summed component signal and the second summed component signal and compensates for polarization skew between the antenna array and a source.

Communication system with broadband antenna

A compact mobile satellite communications system, including an integrated direct wave antenna and a low profile precision antenna positioning system, where the integrated direct wave antenna is configured to provide the minimum swept volume when steered and pointed such that it moves completely within a ten inch sphere, which provides an advantage when the system is mounted on a moving vehicle such as an aircraft, and the integrated direct wave antenna includes a refractive component as well as down conversion electronics to provide a L band signal output.

Compact high efficiency intregrated direct wave mobile communications terminal

A communication system including an antenna array with feed network coupled to communication electronics. In one example, a communication subsystem comprises a plurality of antennas each adapted to receive an information signal and a plurality of orthomode transducers coupled to corresponding ones of the plurality of antennas, each OMT is adapted to provide at a first component signal having a first polarization and a second component signal having a second polarization. The communication subsystem also comprises a feed network that receives the first component signal and the second component signal from each orthomode transducer and provides a first summed component signal at a first feed port and a second summed component signal at a second feed port, and a phase correction device coupled to the first and second feed ports and adapted to phase match the first summed component signal with the second summed component signal.

A communication system and methodology for providing a signal of interest to at least one movable platform, for possible use by passengers associated with the movable platform, from an information source, where the movable platform is not within a signal coverage area of the information source. The method includes transmitting an information signal with a transmitter located at the information source, receiving the information with a first transmitter/receiver unit located on a first movable platform within the signal coverage of the information source, and re-transmitting the information signal with the transmitter/receiver unit to a receiver located on a second movable platform that is not within the signal coverage area of the information source. The method may further include repeating the steps of receiving and re-transmitting the information signal with at least one additional transmitter/receiver unit, to provide the information signal between the first movable platform and the second movable platform.

Low-height, low-cost, high-gain antenna and system for mobile platforms

A leaky waveguide antenna array that receives and/or transmits electromagnetic signals includes a plurality of radiation waveguides disposed in parallel to each other on a surface plane to form the antenna array. A feed waveguide is located below the surface plane and provides an electromagnetic signal to the plurality of radiation waveguides and/or receives a plurality of electromagnetic signals from the plurality of radiation waveguides and provides a composite electromagnetic signal at an output of the feed waveguide. Each of the plurality of radiation waveguides has a waveguide axis and includes a plurality of apertures arranged in a direction of the waveguide axis. The feed waveguide includes a first section of waveguide having a first end connected to an input/output port. The first section of waveguide has a height substantially the same as the height of each of the plurality of radiation waveguides and the first section of waveguide has a second end coupled to a first junction point. The first junction point transitions from the first section of waveguide to a second section of waveguide and a third section of waveguide that each have a height that is substantially half of the height of the first section of waveguide. The second section of waveguide transitions with an upward sloping ramp to the substantially half height of the first section of waveguide. The third section of waveguide transitions with a downward sloping ramp to the substantially half height of the first section of waveguide. The third section of waveguide is substantially a mirror image of the second section of waveguide. The feed waveguide also includes a septum connected to vertical walls of the first, second and third sections of waveguide which aids in the transition from the height of the first section of the waveguide to the height of the second section and the third section of waveguide. Each of the second section of waveguide and the third section of waveguide are coupled to a corresponding first signal port and second signal port of the feed waveguide. Each of the first signal port and the second signal port are coupled to a corresponding one of the plurality of radiation waveguides.

A tray assembly uniquely configured to be removably attached to a chair armrest such as that of a beauty salon includes a U-shaped clamp having a pair of parallel sidewalls and an end wall therebetween. A sidewall has an aperture for threadedly receiving a bolt allowing the clamp to be quickly attached to the chair arm rest. The opposing sidewall and the end wall each have an elongated, substantially wedge shaped groove for slidably receiving a tongue on the accompanying tray member. The tray member includes a substantially rectangular support surface having four peripheral edges with an elongated portion integrally extending from an edge thereof. On the upper side of the support surface is a substantially rectangular recessed portion with one or more beverage receptacles therein. The lower side has an elongated, wedge shaped tongue slidably received within either of the grooves on the clamp. The beverage receptacles have one or more freezable gel packs removably received therein for maintaining a beverage at a substantially constant temperature.
