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.
