Abstract :
Detailed field plots showing the structure of the measured electromagnetic (EM) field in a three-dimensional volume of an open-field site, due to a variety of source antennas, are presented. Measured antennas include broadband antennas, such as the biconical and log-periodic antennas, as well as dipole antennas in the 50-MHz to 1-GHz frequency range. The results are in the form of contour maps of the amplitude and phase of the EM field in three cross-sectional planes containing the central axis of the antenna in a typical 3-m site configuration. Both horizontally and vertically polarized antenna orientations are studied.<>
