Antennas: Advanced Technology Integrated/Custom

Our vast experience in antenna technology (over 1,000 designs) offers a solid starting point toward customization for any need. Conformal (built into existing structure) aircraft and shipboard antennas typically allow for larger antenna apertures that can be tuned more efficiently, yielding higher gain and better coverage than standard bolt-on antennas. Co-location of several antenna functions is also possible within these larger structures. The introduction of EDO heritage electronics capabilities (diplexers, switching matrices, Butler matrices, preamplifiers, filters and beam forming networks) within the antenna structure is a natural progression which can improve overall system performance. Typical airborne installations include vertical stabilizers, fincaps, ventral fins, wing leading edges and access doors. We have produced products for numerous platforms such as the AV-8B Harrier, F-2, F-5, F-16, F-18, T-38, Boeing 737, AH-1 and OH-58 helicopters and various unmanned air vehicles.

Examples of shipboard installations include wall panels, periscopes or composite masts. Our DF360-1 Circular Array Interferometer is one prime example of a highly integrated submarine mast structure.

One specialized ground product is our CA 1530 Airport Surface Detection Equipment (ASDE) tower mounted antenna system for the monitoring of airport ground traffic. This shaped beam reflector utilizes a lightweight composite reflector and circularly polarized 15 GHz feed which is used in concert with both Northrop Grumman (Norden) and Thompson (Cardion) equipment.

Airborne conformal designs also lend themselves to the addition of LO or RCS technologies which can be incorporated for both new and existing airborne and shipboard platforms. Prior experience with LO antenna requirements has been demonstrated for several platforms and we recently enhanced our existing capabilities with a new strategic partner.

An alternate approach to LO conformal antennas or for low ground clearance platforms is a retractable blade antenna that can be deployed when required. Our C177 and CNI29 series are examples of these 1.5 to 1220 MHz capable units that can deploy or retract within seconds, even under full aerodynamic load.

Broadband (3.0:1 bandwidth) horn antennas such as our RFS series provide typical VSWR levels of 1.4:1 over the 6 to18 GHz frequency range. Commonly used for anechoic chamber threat simulation testing these antennas provide excellent amplitude and phase tracking.

Our expertise, which spans the HF through MMW frequency range, combined with our ability to bring a concept to a production product regardless of the particular platform's environment, permits us to custom design an antenna for any application. Design experience encompasses single standard apertures through multiband, multielement arrays for the most severe vibration and temperature (300 degrees Fahrenheit continuous, 3000 degrees Fahrenheit short duration) environments, including artillery shells and space.
