Near-field calculation for reflector antenna with shape of asymmetrical cutting from a paraboloid of revolution

Abstract

Radiation field calculation method is considered for reflector antenna in its near-field region. The method is based on using field integral representations for reflector antenna obtained with Lorenz reciprocity theorem. The mirror edges contribution to antenna full field is considered using solving simulative problem of plane monochromatic wave diffraction at perfectly conducting wedge. The near-field calculation results for reflector antenna with shape of asymmetrical cutting from a paraboloid of revolution are presented.
