Spiral Antennas

Overview

CAES is a leading designer and manufacturer of spiral antennas. CAES Spiral Antennas are standard equipment on advanced electronic warfare systems worldwide and are the product of choice for the most demanding defense applications.

Key features include:

  • Designed to radiate or receive RF energy over very wide bandwidths while maintaining a constant beamwidth, low axial ratio, and minimal squint
  • Available with near lossless cavities for applications where bandwidth is less critical than efficiency. These relatively narrow-band (3:1 bandwidth typically) 
  • Amplitude- or phase-matched sets for radar warning and precision direction finding
  • Ability to withstand severe airborne, ground, and maritime environments (surface- and sub-surface)
