Abstract : The report describes several investigations conducted during the past year in the area of log-periodic antennas. The work on inductively loaded, foreshortened log-periodic antennas included measurement of patterns and gains of antenna models which were foreshortened by various amounts. Capacitive top-loading of monopole antennas was also investigated to develop other techniques for log-periodic antenna foreshortening. Finally, a new, flat plate boom configuration for stronger and less expensive construction of log-periodic dipole array antennas is described. (Author)
