Free Space Antenna Factors through the use of Time-Domain Signal Processing



Dennis G. Camell, Robert T. Johnk, David R. Novotny, Chriss A. Grosvenor


This paper demonstrates the usefulness of time domain processing to determine free-space antenna factors,FSAF, for EMC antennas. Procedures are explained and data is provided from 30 MHz to 9 GHz. We investigate time gating of dense frequency packed insertion loss data obtained with an ultrawideband measurement system. These results show the advantage of time-domain gating to provide reliable results for free space antenna factors of EMC antennas.
