A method and a simple equation for determining the magnetic complex antenna factor (M-CAF) of a shielded loop antenna are presented. The investigated shielded loop antenna has two output ports of which outputs are differentially combined in time domain. The low-directivity of this loop antenna is useful for mapping magnetic fields. The proposed method is based on an equivalent circuit of the antenna system. The derived equation makes it possible to determine the M-CAF from the calculated effective length of the loop element and the measured reflection coefficient at an output port. The proposed method is confirmed by comparison between the waveform reconstruction using the M-CAF and the theoretical calculation for an electromagnetic pulse radiated from a monopole antenna on a ground plane.
