Compact Broadband Antenna

 PDF Version

The U.S. Navy seeks to commercialize U.S. Patent 6,667,721 (Compact broadband antenna).

Market Need/Problem

  • Resolution of many problems associated with multiple individual antennas including co-site interference, blockage, and overall real estate availability
  • Joint Tactical Radio System’s (JTRS) goal to reduce 25 to 30 radio families into one system to cover 2 MHz to 2 GHz, and beyond, using very few antennas
  • In 2002, the FCC opened the spectrum in the 3.1-to 10.6-GHz range for Ultra-Wideband (UWB) applications, with future prospects such as wide area networks
  • The Technology

    SSC Pacific has developed a technology that uses a bicone antenna configuration as a feed transformer and exponentially tapered reflector fins to radiate the antenna’s energy (could be modified to a discone w/groundplane design). This permits a device to transmit and receive capability over a range of 130 MHz to 9.0 GHz (capable of improvements to over 10 GHz). Additionally, impedance matched to 50 ohms and this antenna can be omni-directional and vertically polarized.

    Key Benefits

  • Compact design decreases the traditional bicone antenna diameter from 56 to 24 inches, a 60% reduction (24-inch height when enclosed in a cylindrical fiberglass tube)
  • Scalable to fit frequency requirements – for UWB applications the unit would have approximately one inch dimensions
  • Return loss is reduced over operating frequency bands compared to classical designs (refer to graphs)
  • Development Status

  • U.S. Patent issued: 6,667,721
