Many different antenna types can be employed depending on the specific military application.
Wideband antennas are those with ranges from 150MHz to 40GHz and tend to be used in military systems that require spectrum-agility or multi-functionality in electronic warfare applications. They can be used as cellular band countermeasures as well as countermeasures to IED (improvised explosive device) triggers. As wideband omni antennas they can be stacked to allow overlapping frequencies for multiple applications, offering high isolation between bands.
Ground and naval applications tend to use extended performance, broadband omni antennas operating on the frequency band covering 960MHz to 1275MHz to allow communication with airborne platforms.
Unmanned Systems require a more diverse range of antennas for data communications and command & control systems as well as payloads. These include:
C-band 4.4-5.0 GHz directional, sector, multi-sector and omni-directional antennas provide a higher level of security and deliver high data rates for point-to-point or point-to-multipoint applications.
Radar systems use various antennas including Stripline and Waveguide for CW Doppler, FMCW, fixed-beam pulse, and reflectometer arrays.
High-gain radar or communication systems use wideband, possibly multi-octave, radiation patterns and VSWR (Voltage Standing Wave Ratio), sometimes with wide angle scanning.
Low-gain mobile communication systems have simpler radiation pattern conditions and need wideband VSWR.
Lastly, body-worn antennas are an evolving military communication application that can be incorporated into troops’ clothing.
