Ansys HFSS is a commercial finite element method solver for electromagnetic structures from Ansys. 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.
Select the menu item HFSS > Fields > Edit Sources • Drag it to the side so you can see the Active S-Parameters Plot • Change the values in the Magnitude and Phase fields • Click Apply to see the updated results in the Active S-Parameters Plot. the plot.
HFSS refers to food and drink products that are high in (saturated) fat, salt or sugar according to the Department of Health's Nutrient Profiling Model (NPM). Foods that score four or more, and drinks one or more, are classed as HFSS.
An Interpolating sweep estimates a solution for an entire frequency range. HFSS chooses the frequency points at which to solve the field solution so that the entire interpolated solution lies within a specified error tolerance.
HFSS Information. Once the client comes up, go to start and go to ANSYS menu GO to Workbench and within Workbench click HFSS. Once there, click on Geometry (or someting else in the menu of the HFSS) and then the Electronics Desktop will open up. That is HFSS!!!
Change Fmin and Fmax to the desired values in the frequency range settings dialog box (opened by pressing the “Frequency range†icon or choosing Solve ⇨ Frequency) and store these settings by pressing the OK button.
In HFSS go to HFSS tab> Results> Create Far Filed report> Rectangular Plot>select trace tab> Prime Sweep: select Freq> select Gain > select dB> go to familes tab > select Theta=0 and Phi=0 >then click New Report.
After you obtain the 2D Radiation Pattern, Right Click on the screen, then a menu will be displayed with "Markers" at the top, next you can find "Trace Characteristics". Trace Characteristics> Add. Add Trace Characteristics window opens. Put x value 3 for 3dB beamwidth in the table below.
E-Plane is always the plane that contains the electric component of the EM radiation and the direction of maximum radiation. The E plane will dictate whether the linear polarization is horizontal or vertical. VERTICALLY POLARIZED antennas have an E plane that relates to the VERTICAL / YZ / ELEVATION plane.
In the field of antenna design the term radiation pattern (or antenna pattern or far-field pattern) refers to the directional (angular) dependence of the strength of the radio waves from the antenna or other source.
The azimuth plane pattern is formed by slicing through the 3D pattern in the horizontal plane, the x-y plane in this case, just as you would slice through a bagel. Notice that the azimuth plane pattern is non-directional, that is, the antenna radiates its energy equally in all directions in the azimuth plane.
E-plane means direction of electric field plus direction of propagation and H-plane means direction of Magnetic field plus direction of propagation.
The phi angle (φ) is the angle from the positive x-axis to the vector's orthogonal projection onto the xy plane. The theta angle (θ) is the angle from the z-axis to the vector itself. The angle is positive toward the xy plane. The theta angle is between 0 and 180 degrees.
