3D Radiating and Focusing Antenna System

The 3D antenna system focusing the radiation in a far zone based on the linear array consisting of declining semitransparent plane arrays is examined in paper. The quasioptical conditions are fulfilled for the system's geometry. The distance between separate elements of system satisfies to the Fresnel zone conditions, and the radiation pattern (RP) of system is calculated in its far zone. The separation of variables is assumed in the apertures of separate elements and in the RP's components. The explicit formulas are derived for the field values in the constituent elements of antenna and created RP. The ability of system to create the RPs of the different kind is supported by computations.
