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



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


This paper demonstrates the usefulness of time-domain processing to determine free-space antenna factors (FSAF) for electromagnetic compatibility (EMC) antennas. Our procedures are explained and data are provided for frequencies from 30 MHz to 9GHz. 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.
