dc.description.abstractThe Double Delta antenna is an HF communication antenna which exists in many forms throughout military' communication commands. Performance characteristics for existing designs are presently unknown and are required in order to recommend an optimum design. This thesis investigates Double Delta antennas used by the US Army (lowband and highband), the US Air Force (lowband and highband), and a commercial model. Selected models are analyzed by a computer simulation method using the Numerical Electromagnetics Code (NEC). The antenna designs are investigated to determine optimum performance characteristics over the 2 - 30 MHz range of frequencies. The parameters calculated were input impedance. VSWR, and antenna gain radiation patterns. For the performance of the antennas when sited near lossy ground, the Sommerfeld method was employed. Finally the results of the evaluation are presented and recommendations are made.en_US
