Since the approximation described above assumes that the radius of curvature is large compared to the wavelength, the diffraction from edges needs to be handled separately. Holds best for short wavelengths, and it assumes that the radius of curvature of the scatterer is large compared to the wavelength.
#CST MICROWAVE STUDIO WIKIPEDIA PATCH#
The substrate has twice the width and length of the patch antenna, that is, 2W and 2L. W and L are the width and length of the patch antenna. The antenna that will be designed is shown in Fig 1.
The scattered field is thereafter computed by integrating these currents using physical optics (PO), by the Kirchhoff's diffraction formula. In this part of the tutorial, we will use the dimension calculated in the first part to design the patch antenna in CST microwave studio. The first step in the SBR method is to use geometrical optics (GO, ray-tracing) for computing equivalent currents, either on metallic structures or on an exit aperture.
