Abstract:
The problem of synthesis and analysis of
circular antenna array for the azimuth scanning in ultra-wide band (more than
1:100) is considered. The review of UWB radiators used as the
elements of antenna arrays is given. The results of the
matching characteristics analysis of various modifications of TEM horns have
been obtained with the use of a numerical-analytical theory and FEM are given. Numerical
modeling of the matching characteristics of and radiation of a circular antenna
array of asymmetrical loop TEM horns as elements is done. Comparison of the
results of numerical simulation and physical experiment is conducted.
Keywords:
ultra wideband antenna, TEM horn, circular
antenna array.
