Description
Summary:The synthesis of electromagnetic pulses with an extended spectrum is studied using summation of radiation pulses with different frequency bands in free space. The analytical estimation of the radiation spectrum with maximum width is performed for an array of combined antennas excited by bipolar pulses with durations of 0.5, 1, 2, and 3 ns. A combined antenna with an extended matching band is developed. The possibility to obtain ultrawideband radiation with a spectrum width of more than four octaves for an array of combined antennas excited by bipolar pulses with durations of 0.5, 1, 2, and 3 ns is experimentally demonstrated.
