What is lumped port?
Lumped ports are used to excite or terminate passive circuits and antennas, as well as to compute frequency responses of devices, such as impedance matching and insertion loss in terms of S-parameters. There are a couple of conditions to obtain physically valid S-parameters while using lumped ports.
What is the main difference between a wave port and a lumped port?
in general, go with wave port if your design is using probe fed, and lumped port for line feeding. Generally you should use lumped port if the feed is a line and if the reference impedance is known. A lumped port always needs a reference impedance. 1.
What is PEC in HFSS?
The Perfect Electric Conductor or PEC Boundary is the HFSS default boundary that is applied to all outer faces of the solution space. It represents a lossless perfect conductor. This boundary can also be used to create a symmetry plane if it is placed on an outer face of the solution space.
What is HFSS in antenna?
The acronym stands for high-frequency structure simulator. HFSS is one of several commercial tools used for antenna design, and the design of complex radio frequency electronic circuit elements including filters, transmission lines, and packaging.
What is a Waveport?
Wave port represents the surface through which a signal enters or exits the geometry. Hence 2 ports are required to be defined. HFSS assumes that each wave port you define is connected to a semi-infinitely long waveguide that has the same cross-section and material properties as the port.
What is PEC and PMC?
OptiFDTD now has options to use Perfect Electrical Conductor (PEC) and Perfect. Magnetic Conductor (PMC) boundary conditions. You can choose which boundaries. use the new conditions, and Anisotropic PML can be used for the remaining. boundaries.
What is mesh in HFSS?
The automatic adaptive meshing procedure at a single frequency is the cornerstone technology that enables Ansys HFSS to accurately and efficiently calculate the electric fields in a model. The process starts with Ansys HFSS translating the modeled geometry into a conformal, inhomogeneous tetrahedral mesh.
What is Ansys mechanical?
Ansys Mechanical is a finite element analysis (FEA) tool that enables you to analyze complex product architectures and solve difficult mechanical problems. You can use Ansys Mechanical to simulate real world behavior of components and sub-systems, and customize it to test design variations quickly and accurately.
What is the importance of Ansys?
Ansys Mechanical finite element analysis software is used to simulate computer models of structures, electronics, or machine components for analyzing strength, toughness, elasticity, temperature distribution, electromagnetism, fluid flow, and other attributes.
What is Waveport HFSS?
What is integration line in HFSS?
The integration line is used to extract the impedance for a given waveguide cross section. There are three methods to extract the impedance in HFSS: Zpi, Zpv, Zvi. The Zpi (default) uses the initial power, 1Watt, and the enclosed current, I, to determine the impedance.
