SHAPED REFLECTOR ANTENNA ANALYSIS BY GRAPHICAL PROCESSING METHODS

摘要

This paper presents the application of GRECO code to obtain the radiation pattern of single reflector antennas. Shaped reflectors with arbitrary geometries are modelled by CAD software. The GRECO graphical processing technique [3][4] [5] is used in order to extract the relevant geometrical information from the CAD geometry database. Surface reflection and edge diffraction are respectively analyzed by Physical Optics approximation and Equivalent Edge Currents Method.
