Multichannel antenna systems for radiation of high-power ultrawideband pulses

To realize attractive possibilities of ultrawideband (UWB) radars, it is necessary to develop multichannel antenna systems for radiation and control by characteristics of high-power electromagnetic pulses localized in space and time. In this paper, new results of single combined antenna investigations are presented. However, the main consideration is given to the investigation of interaction of combined radiators and plane electrical monopoles in linear arrays including the investigation under conditions of steering by the wave beam. Possibility to synthesize the electromagnetic pulse in free space in order to expand radiation spectrum has been investigated theoretically.
