Antennas of vehicles landing on a planet surface

Abstract

The antenna systems designed under the international projects ``Mars-96`` and ``Phobos`` are described. The antenna system of Small station landing on Mars, in flight is packed under protective petals of the station and is opened on a surface with the help of flexible legs. The original scheme of excitation in the form of compact strip-geometry is described. The antenna system of the mobile vehicle landing on Phobos, provides the omnidirectional pattern on the basis of the combination of antenna methods with methods of processing of the received signal. The high efficiency of the antenna results from its construction in the form of an active antenna.
