Time-domain processing to determine free-space antenna factor

This paper demonstrates the usefulness of timedomain processing to determine free-space antenna factors (FSAF) for electromagnetic compatibility (EMC) antennas. Procedures are explained and data are 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 signal processing to provide reliable results for the free-space antenna factors of EMC antennas.
