Electromagnetics

Antenna & Electromagnetic Modeling Capabilities

Antenna Modeling, Fabrication and Experimental Validation

  • Extensive use of most recent versions of NEC and other advanced numerical analysis tools
  • Treatment of dielectrics, underground wires, and various wire thicknesses
  • Analysis of non-linear materials (plasma, territes, EBG, and complex meta-materials)
  • Analysis of reflector and cavity-type antennas
  • Effects of radome on various antennas
  • Treatment of patch, microstrip and MMIC
  • Special HF antennas and arrays for broadband and tactical deployment
  • Transportable satcom antenna
  • Loop antennas for VLF-LF-HF bands
  • Feed system optimization for specific situations
  • Dual reflector antennas
  • Telemetry antennas
  • Radiometric antennas
  • L-Band ground terminal mobile and fixed

Some Practical Systems Delivered to U.S. Government Agencies

  • Short backfire antennas optimized for low cross polarization (NASA)
  • Helix antennas for extremely rugged configuration (DARPA)
  • Radome shielding spiral antenna (U.S. Navy)
  • ELF antenna with noise » 10-10 gauss/ HZ (NSF)

Ultra-Wideband Antennas

  • We have designed ultra-wideband antennas covering gain and impedance performance over 60:1. It uses broadband elements and applies a genetic algorithm for loading and matching.

3-D FIPA Antenna

  • A novel 3-D FIPA antenna has been designed that offers extremely wide bandwidth without the grating lobes. The antenna occupies 3-D structure and the beam width, bandwidth and phasing can be controllable.

Broadband Dipole

  • Modification of the fat dipole configuration using adaptive NEC has resulted in some unique broadband dipole design. The dipoles can cover a wide frequency range and are extremely simple to construct. The most likely applications are in HF and VHF.
