A numerical method to calculate periscope antennas
Abstract
After establishing the radiation field of a parabolic mirror irradiated by a Huygens optical source, the effect of a plane reflecting mirror was determined by assimilating the mirror to an iris with an opening depending from the mirror projection in the radiation direction. Numerical application is presented taking into account the focal distance of the system, and the opening angle of the parabolic antenna leading to a simple antenna optimization.
