Abstract
This paper discusses the use of a three-loop antenna system (TLAS) for
near-field measurement of electric and magnetic fields from video dis
play terminals (VDT's). We calculated the electric and magnetic dipole
moments to derive the electric and magnetic field patterns in the nea
r field region, Electric and magnetic fields, emitted by several diffe
rent models of VDT's, were evaluated with the TLAS and were compared w
ith those measured by conventional electric and magnetic field probes
at different distances and directions from VDT's. A good correlation (
+/-1.6 dB) between the two measurement techniques. was found, This agr
eement is within the accuracy (+/-2 dB) of the conventional field prob
e measurements.
