    Abstract: A calibration network system for an array antenna and method for calibrating of the array antenna are described. The system includes a pair of rectangular waveguides stacked in parallel relation to each other and spaced apart at a distance of a quarter of an operating wavelength. The rectangular waveguides includes through-holes extending through a side-wall of the stacked rectangular waveguides from a bottom of a lower waveguide to a top of an upper waveguide to accommodate coaxial transmission lines. The side-wall has openings between the through-holes and an interior region of the rectangular waveguides in order to provide coupling of the coaxial transmission lines into the pair of rectangular waveguides. The system includes 90 degree phase shifter coupled to the upper rectangular waveguide, and a power divider/combiner coupled to a reference T/R Module, to the 90 degree phase shifter and to the lower rectangular waveguide.
