First Demo Of K-band Satellite Connectivity With 3-Inch Antenna
Melbourne FL (SPX) Aug 12, 2004 Harris Corporation, in cooperation with Lockheed Martin and Rockwell Collins Government Systems, recently demonstrated a first-ever small-diameter, multi-function advanced data link prototype antenna that accurately receives signals from military communications satellites. The specialized, phased array antenna, developed by Harris under a cooperative R&D effort with Lockheed Martin, is less than three inches in diameter and ideal for use onboard military fighter jets and for other tactical applications. "Harris is a leader in high-performance, high-density phased array antennas that cover a broad range of frequency bands and address the unique and harsh demands of space, airborne, shipboard and ground-mobile environments," said Dan Pearson, president, Department of Defense Programs business unit, Harris Government Communications Systems Division (GCSD). "This first-of-its-kind, K-band downlink-capable, three-inch antenna opens the door to a wide range of new applications that will allow satellites in this frequency band to link with tactical airborne platforms, particularly stealth aircraft such as the F/A-22 and F-35, which require much smaller, lighter antennas." "We are very pleased with the success of this demonstration, and the strong cooperative effort among all those involved." The new antenna is the first small-diameter phased array that can support air-to-air communications and also provide reception of K-band satellite communications signals. It was integrated with Rockwell Collins' Single Channel Anti-jam Manportable (SCAMP) Terminal down conversion and modem hardware. The antenna was subsequently able to support successful end-to-end communications at the maximum low data rate of 2,400 bps.
