Computer modeling of the parabolic dish antenna with a special feed for left and right-hand circular polarization

Petr Vágner, Miroslav Kasal, Tomáš Urbanec, Ondřej Baran

Abstract

This paper deals with a computer model and the simulation results of the parabolic dish antenna. At first, design of the feed antenna used for illumination of the dish is described and its parameters are modeled and optimized using two EM field solvers based on the finite elements method. Finally, the feed antenna is put together with the parabolic dish reflector and the whole system is simulated to obtain radiation pattern and estimated gain.
