Prediction of the Fresnel region field of a compact antenna test range with serrated edges

The performance of antenna systems is always influenced by diffraction effects. Diffraction problems may be analysed using physical optics or geometrical theory of diffraction. Here, the Fresnel field of a rectangular aperture with serrated edges is analysed using physical optics. The method can be applied very succesfully in compact antenna test range design for a fast prediction of the test-zone field performance.
