Description of the task Following aspects are under investigation: 1. Filters for the import of specific CAD files and the extraction of SPICE parameters enhance design possibilities and save time. CST Microwave Studio version 2019 with time domain solver is used for simulation and results. CST MWS enables the fast and accurate analysis of high frequency (HF) devices such as antennae, filters, couplers, planar and multi-layer structures and SI and EMC effects. The SBR method can be extended with physical theory of diffraction (PTD) in order include edge diffraction in the model. CST MICROWAVE STUDIO (CST MWS) is a specialist tool for the 3D EM simulation of high frequency components. 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. Design & Study of Microstrip Patch Antenna.The project here provides a detailed study of how to design a probe-fed Square Micro-strip Patch Antenna using HFSS, v11.0 software and study the effect of antenna dimensions Length (L), and substrate parameters relative Dielectric constant (r), substrate thickness (t) on the Radiation parameters of Bandwidth and Beam-width. The scattered field is thereafter computed by integrating these currents using physical optics (PO), by the Kirchhoff's diffraction formula. 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. 2 Implementation in commercial software.
