Electronic Warfare (EW) Antennas

Effective countermeasures for field operations are becoming mandatory as commercially available RF products continue to be used for IED triggers.

Denying use of the RF spectrum to the enemy is of critical importance. As RF sources and amplifiers are developed to cover wider bands at higher power, it is important that antennas are developed in parallel.

The antennas must cover all specified bands, peak gain must be on the horizon, and they must be small enough for use by foot soldiers and rugged enough for vehicle applications.

We have a portfolio of ultra wideband (UWB) omni antennas in the range 150MHz to 40GHz to cover all of the bands in which high power amplifiers operate.

Multistack omni arrangements have been developed as well as specific antennas with high gain for cellular band countermeasures.

Ultra-Wideband Omni Antennas

  • Biconical omnis that are fully efficient, vertically polarised Bandwidths from 3:1 to 30:1 are achievable
  • Frequencies from 100MHz to 18GHz
  • Ground plane independent
  • Vertically polarised
  • Elevation HPBW typically 30 to 60 degrees
  • Typically 0 to 2dBi gain across the band
  • Excellent azimuth patterns
  • High power
  • Peak gain on horizon across all bands

Multistack Omni Antennas

Wideband omni antennas can be 'stacked' so that several antennas may be designed into a single housing, which provides a single mounting point on any vehicle.

New feed through technology allows multiple antennas to be co-located within the same housing.

  • Overlapping frequencies for multiple applications
  • High isolation between bands
  • 200W per band simultaneously
  • Good return loss across all bands

Directional Antennas

A wide range of directional, ultra-wideband, high power, circular polarised and spiral antennas are available. This range is continually expanding with new developments undertaken to meet customers' deployment requirements.

  • High power (Tested to 150W in some cases but capable of more)
  • Highly directional for focussed beams
  • Low profile
  • High gain (Up to 32dBi)
  • Rugged
  • Cavity backed spiral antennas
  • High power spiral antennas
