Abstract : The purpose of this work was to conduct theoretical study, mathematical analysis and experimental verification of research-type problems relted to the advancement of the state-of-the-art in the field of antenna for ground-based aplications. Sixteen individual tasks were completed in technical areas related to array antennas, transmission lines, electromagnetic wave scattering and field measurements. Typical tasks in these areas include: studying the effects of removal of elements on array antenna radiation patterns; developing design techniques for reducing side lobe radiation in linear and planar arrays; examining and minimizing VSWR caused by multiple discontinuities in transmission lines; experimentally examining mutual coupling effects in arrays; and developing a new technique for measuring diffraction fields. Work accomplished on each task undertaken during the course of this investigation has been published in separate technical reports and is summarized in this report. Individual task reports should be consulted for technical details.
