WRAPAROUND ANTENNAS
™
The Haigh-Farr Wraparound™ is a self-contained omnidirectional
antenna for cylindrical or conical shaped bodies. A single point feed
is used and no external splitters, combiners or cable harnesses are
required for installation. The antenna is conformal, and may be
mounted flush, or on the exterior of the vehicle.
Designs are available from 300 MHz to 13 GHz with typical
applications including Flight Termination, GPS, Telemetry, Data Links
and Transponder. Multiple antennas may be combined within the
same physical Wraparound™, providing a multi-task solution in a
single, compact package.
The Wraparound™ antenna has been flown on vehicles from
subsurface sea to space, including high mach kinetic kill weapons,
high G projectiles and re-entry vehicles.
The Haigh-Farr Wraparound™ antenna has been qualified for use
on several high performance vehicles flown on test and launch ranges
throughout the United States and Europe.
For high aero-heating applications an ablative heat shield may be
added to the antenna.

DESIGN CAPABILITY
With over 30 years of design history, your antenna
configuration/performance requirements may already exist,
or extrapolations from similar Haigh-Farr designs may be
possible with minimal effort. If a design meeting your
requirements does not exist, Haigh-Farr has the experience
and modeling capability to customize a solution. Contact
Haigh-Farr for a review of your antenna requirements.
