How the Green’s Functions May Be Used for Correct Measurements of Homogeneous and Inhomogeneous Dielectric Sheets

The Green’s functions of layered structures are used for analysis of measurement errors of transmitting losses through homogeneous and sandwich-type antenna radomes. Influence the spherical waves excited by radiators in the near zone is under investigation. As the simplest antenna, the Hertz dipole was used for calculations. The model of equivalent electric circuits was used for layered structure modelling. The transmitting losses of electromagnetic waves versus frequency for different dielectric sheets are shown. Influence of the distance between antennas on the transmitting loss measurements is analyzed.
