Abstract: An explanation is given for the existence of two radiation centers of a combined antenna in the mode of its excitation by bipolar voltage pulses of nanosecond duration. It is shown that the existence of spatially separated radiation centers in the combined antenna is primarily related to the geometry of the TEM horn used in the antenna as an electric-type radiator.

Keywords: combined antenna, ultra-wideband antenna, phase center, radiation center
