Antenna Design and Manufacture

Antennas

PPM Systems provide antennas for a range of defence applications, including communications, jamming, spoofing and threat-emissions. Antenna bandwidths range from 20 MHz to 40 GHz in static, vehicle and manpack configurations.

Stacked antennas provide multiple band capability in a single antenna structure.

Complex antenna solutions for radar simulation applications can provide high power RF handling with multiple bands, in extremely demanding environmental conditions.

Electronic Warfare – Jamming

Electronic Warfare - military truck driving through sandy terrainPPM Systems supplies high performance, ruggedized RF jamming antenna systems for the military and security industry. These antennas have been successfully deployed throughout the world, providing excellent gain and RF threat spatial coverage.

  • Bandwidths of 20 MHz to over 6 GHz
  • Minimal mounting space
  • Vehicular, manpack and fixed site applications.

Both omni-jamming and high-gain jamming antennas can handle the high RF power required for mission success in harsh environments.

Feeds

Satcom antenna and feedsPrime Focus & Off-Set Feeds: Used with single reflector geometrics, where the feeds are optimised to match the reflector’s focal length and diameter ratio, as well as the primary pattern edge taper of the feed.

Cassegrain & Gregorian Feeds: Used in dual reflector antenna systems to achieve high efficency, low antenna noise temperature and good cross-polarisation.
