Design of Microstrip Patch Antenna using ANSYS HFSS

This work presents the design and simulation of a rectangular microstrip patch antenna using ANSYS HFSS, including all major analysis steps. The antenna structure is modeled with proper substrate and ground plane selection, and excitation is applied via a suitable feed configuration. The simulation captures key excitation waveforms, observes the return loss and VSWR, and generates far-field radiation plots. E-plane and H-plane radiation patterns are plotted to examine field distribution and directivity. The project further analyzes the electric and magnetic field radiation, providing detailed insights into antenna behavior. Gain versus frequency is plotted to evaluate performance across the band, confirming the antenna's suitability for targeted wireless applications. It also addresses radar applications, satellite communication, and Internet of Things products, and discusses 3D EM design considerations; parameters necessary to analyse the antenna can be viewed in 2D and 3D models for accurate analysis.
