Beginners can find a book and follow the examples in it. Master the basic operation methods. After doing more things, you can gradually accumulate experience. It's best to know the principles of hfss, such as finite element algorithm and self-adaptation, which can help you use the software better. The most important thing is to have a clear physical concept. After all, hfss is just a tool to solve problems better.

After more than 20 years of development, HFSS has become the first choice tool and industry standard for high-frequency structural design with its unparalleled simulation accuracy and reliability, fast simulation speed, easy-to-use operation interface and stable and mature adaptive mesh generation technology. It has been widely used in aviation, aerospace, electronics, semiconductors, computers, networks, communications and other fields to help engineers design various high-frequency structures and programs efficiently. Including RF and microwave components, antennas, antenna arrays and radomes, high-speed interconnection structures and electric vacuum devices, the target characteristics and electromagnetic compatibility/electromagnetic interference characteristics of the system/components are studied, thus reducing the design cost and materials, shortening the design cycle and enhancing the competitiveness.

HFSS——Ansoft's three-dimensional electromagnetic simulation software, high-frequency structure simulator, was acquired by ANSYS. It is the world's first commercial electromagnetic field simulation software with three-dimensional structure, and is recognized as an industrial standard for the design and analysis of three-dimensional electromagnetic fields. HFSS provides a concise and intuitive user design interface, an accurate and adaptive field solver, and a powerful post-processor. It has unprecedented electrical performance analysis ability, and can calculate S parameters and full-wave electromagnetic fields of three-dimensional passive structures with arbitrary shapes. HFSS software has powerful antenna design function, and can calculate antenna parameters, such as gain, directivity, far-field pattern profile, far-field 3D pattern, 3dB bandwidth and so on. Draw polarization characteristics, including spherical field component, circularly polarized field component, Ludwig's third definition field component and axial ratio. HFSS can be used to calculate: ① numerical solutions of basic electromagnetic field, open boundary problem and near-far field radiation problem; ② port characteristic impedance and transmission constant; ③ Normalized S parameters of S parameters and corresponding port impedance; ④ Eigenmode or resonance solution of the structure. Moreover, Ansoft high-frequency solution composed of Ansoft HFSS and Ansoft Designer is the only high-frequency design solution based on physical prototype at present, which provides a fast and accurate design method from system to circuit to component level, covering all links of high-frequency design.

HFSS is the most popular antenna design software.
