Ka-Band Space Antenna features stowable, unfurlable design.

Press Release Summary:

High-frequency Ka-band antenna maximizes gain and potential spot beams available to spacecraft manufacturers and Internet service providers. It features radial rib structure reflector design and projected aperture ranges from 3.5-8 m in diameter, with compact stowed configuration suitable for most launch vehicles. Once in orbit, controllers execute maneuvers and send commands to deploy articulating boom and unfurl reflector.

Original Press Release:

Harris Corporation Introduces First Unfurlable, High-Frequency Ka-Band Space Antenna



- Use of Ka-band provides high throughput; improves on-orbit performance and capacity

- Unique design reduces stowed volume and antenna mass

- Markets range from satellite Internet service providers to oil and gas exploration companies

(National Space Symposium, Booth 400) - Harris Corporation (NYSE: HRS), an international communications and information technology company, today introduced an unfurlable space antenna designed to support emerging requirements for high-throughput Ka-band satellites.

The new Harris Ka-band antenna greatly increases the gain and potential spot beams currently available to spacecraft manufacturers and service providers. The increased frequency reuse provided by the additional spot beams enables higher data rates required by providers of bandwidth-hungry services such as satellite Internet, HDTV and 3D TV, and by businesses that transfer large amounts of data between remote locations, such as oil and gas companies and maritime users.

The antenna features flight-proven design elements that have been refined during development and production for US government and commercial programs, including the application of reflective mesh, surface-shaping technology and thermally stable materials. The antenna's architecture leverages Harris' robust radial rib structure reflector design, 40 of which are currently in operation. The projected aperture ranges from 3.5 meters to 8 meters in diameter, with a compact stowed configuration suitable for most launch vehicles.

During launch, the Harris reflectors are stowed onboard the satellite much like an umbrella. Once in orbit, controllers execute a series of maneuvers, and then send commands to deploy an articulating boom and unfurl the reflector.

"This new Ka-band product is a natural extension of our existing offerings for larger apertures, and continues our 35-year legacy of providing high-performance antenna solutions with unmatched performance," said Sheldon Fox, group president, Harris Government Communications Systems. "The Harris solution supports the ever-increasing global demand for higher bandwidth capacity."

With more than 50 reflectors in orbit, Harris is the leading supplier of large reflector apertures and deployable mesh reflector-feed antenna systems. Offerings span UHF band through Ka-band, in sizes ranging from 5 meters to the world's largest commercially available 22-meter reflector. Harris reflector products have the highest surface accuracy design in the industry, while substantially exceeding the specified mean mission duration of the spacecraft and payload.
