Description:
The EFG-3 E-Field generating antenna is designed to generate strong electric field intensities within its' vicinity for use in radiated susceptibility testing systems. The EFG-3 provides a means for dissipating any unused power through the use of a conventional coaxial 50 ohm termination of appropriate power handling capability. This allows the EFG-3 to handle up to 1000 watts of continuous power. The EFG-3 is able to perform in such an efficient manner due to its physical configuration as a radiating transmission line. Highly efficient and conservatively rated broadband transformers are used for impedance matching. This unique matching configuration allows the best possible power to field conversion efficiency by stepping up the source voltage to twice the input value. The EFG-3 can be rotated on its boom axis for both vertical and horizontal polarization and can be combined in multiple bank arrays for an increased useable test area. Pivoting extensions of the top and bottom edges provide access to the area of highest voltage differential such that E-Field intensity can be maximized for testing small objects under extreme field conditions, typically several hundreds volts per meter. The EFG-3 offers a matched load to the driving source over its entire useable frequency range.
