The X-band Satellite Communications on-the-move broadband antenna system is a low-profile, dual-axis mechanically steered, satellite tracking antenna. Designed to give customers ultimate flexibility, the system was developed to support airborne or ground-based communications on-the-move applications over the major X-band constellations including Wideband Global Satellite Communications, Skynet and XTAR, as well as other current and future spacecraft hosting X-band payloads. While utilizing two interleaved, wideband apertures for simultaneous, full duplex Tx/Rx, the X-band antenna system enables the ability to switch right/left hand circular polarizations for both Rx and Tx. The antenna’s low profile reduces the size of traditional dish reflector radomes used for similarly capable X-band communications by nearly half and can be shaped as conformal to an allocated swept volume as necessary.
