Abstract
This article presents the comparative review of ultra-wideband antennas: logarithmic spiral antennas flat, microstrip elliptical antenna, Vivaldi antenna. For computer modeling of antennas used circuit simulation program High Frequency Structure Simulator. There are drawings representing models of antenna radiators with volume radiation patterns. As a result of computer simulation obtained the basic characteristics, such as voltage standing-wave ratio, radiation pattern and input impedance. Comparison of antennas based on them. Also in comparison incorporated the complex form and overall dimensions of antenna radiators. There are advantages and disadvantages of each antenna. Some comparative characteristics are tabulated.
