This thesis investigates the potential of a half square log-periodic array for use by the military over the frequency range of 2 to 30 MHz using a computer simulation technique by numerical methods. Using the Numerical Electromagnetics Code (NEC), a selected model was run in free space and over perfect ground to obtain data for radiation patterns and element currents on the array. After the evaluation of the NEC data, the results of the investigation show that half square log-periodic array with dual feed and switched transmission line has characteristics of a successful log-periodic structure with a unidirectional radiation pattern, over the design frequency range of 2 to 30 MHz, showing promise for military applications.
