Abstract
The requirements for main parameters of the ultra-wideband pulses radiator for multi-element receiving-transmitting video pulse scanning antenna array (VPSAA) are considered. It is noted that the known radiators of simple design do not satisfy the requirements specified.
The petal-shaped radiator of special configuration which is excited by single polarity ultra-wideband pulse and radiates electromagnetic pulse with effective duration of about 1 ns within wide solid angle is has been researched.
In result of computer modeling of the petal-shaped radiator the time, frequency, spectral, energy characteristics and spatial characte-ristics of radiation of the radiator-s computer model which could meet the requirements specified have been received and are given in this paper. In case of overall dimensions about 218×160 mm in VPSAA antenna sheet plane and excitation by video pulse with duration of 0.45 ns the radiator could have simultaneously feeder antenna efficiency of 77%, VSWR of not more than 1.7 within the frequency band above 0.5 GHz, width of amplitude radiation pattern of 90×80°.
The radiation patterns of the model of antenna array on the basis of petal-shaped radiators are shown.
In conclusion it is noted that the petal-shaped radiator could be a component of receiving-transmitting ultra-wideband multi-element video pulse antenna array ensuring two-dimensional wide-angle scanning and could be used as an individual antenna in different purpose radio technical complexes.
