Description

ARA’s Spiral series antennas are large bandwidth, circularly polarized antennas with peak radiation patterns perpendicular to the plane of the spiral. The larger half- power bandwidth of these antennas makes them a good choice for airborne Electronic Warfare (EW) applications such as Radar Warning Receivers, Direction Finding, and Interferometry Systems. In addition, these antennas are used for sensing applications, where very wideband antennas with smaller footprints are ideal. Other applications of spiral antennas include GPS applications, where it is advantageous to have Right Hand Circularly Polarized (RHCP) antennas.

The antennas are available in right-hand circular polarization (RHCP) or left-hand circular polarization (LHCP). ARA also offers these antennas in multi-channel configurations to support amplitude and phase matched requirements for Interferometry sub-systems and applications.
