摘要： Antenna system includes first and second quadrifilar radiating elements. A first one of the quadrifilar radiating elements (QRE) is comprised of a plurality of first bifilar helical loops (BHLs). The BHLs are oriented in a mutual orthogonal relationship on a common axis. A second QRE shares a common feed structure with the first QRE. The second QRE comprises a plurality of second BHLs oriented in a mutual orthogonal relationship on the common axis. The first QRE is tuned for operation in a first frequency band, the second QRE is tuned for operation in a second frequency band different from the first frequency band.
