Electromagnetic Chamber Modifications and Measurements.

Abstract

Improvements to the MIL-STD-1377(Navy) technique are described. Eight field tuner designs were tested and evaluated and a matched long-wire antenna design is described. Chamber performance, as measured by reduced peak-to-peak variations in transmission loss, was greatly improved at the low end of the frequency band (1-2 GHz). The report recommends that MIL-STD-1377 (Navy be amended to include the improved tuning schemes and antennas. A sub-task showed that bare wires pick up RF power according to an inverse square of frequency law and that a halfwave dipole approximation is quite good from 100 MHz to 2 GHz. (Author)
