Ansys workbench tutorial release 15 pdf writer - Ghana Top Trending Searches.ANSYS HFSS is a 3D electromagnetic EM simulation software for designing and simulating high-frequency electronic products such as antennas, antenna arrays, RF or microwave components, high-speed interconnects, filters, connectors, IC packages and printed circuit boards.

Through integration with ANSYS thermal, structural and fluid dynamics tools, HFSS provides a powerful and complete multiphysics analysis of electronic products, ensuring their thermal and structural reliability. HFSS is synonymous with gold standard accuracy and reliability for tackling 3D EM challenges by virtue of its automatic adaptive meshing technique and sophisticated solvers, which can be accelerated through high performance computing HPC technology.

Its reliable automatic adaptive mesh refinement lets you focus on the design instead of spending time determining and creating the best mesh. This automation and guaranteed accuracy differentiates HFSS from all other EM simulators, which require manual user control and multiple solutions to ensure that the generated mesh is suitable and accurate.

UWB antenna with pulse Excitation in HFSS

I'd like to build a waveguide transistion with a coxial line feed in HFSS. But I am not sure how to construct the models. I try to subtract a circle wave port but it seems not correctly.

I just need a example. Thanks very much. I read a tutorial about a microstrip antenna feed and it showed a way: just draw a circlea and a cylinder set this circle as lumped port excitation and the cylincer as the copper pin, then it said it was a simple coaxial waveguide feed exciting.

So I built a box, set 4 faces boundary as copper, and draw a another rectangular overlap the bottom face of the box, then subtract a circle also clone it on the rectangular and set this circle as lumped port excitation. Did I do correctly? In addtion, I want to build a waveguide transistion as an antenna function, so I left one face of the box waveguide as vaccum and built a air box outside the waveguide.

Am I right? No need of making whole SMA connector, you are doing electromagnetic analysis of SMA connector, just make inner conductor of dia meter 1. By the way, which waveguide to coax trnasition you are going to design. Thanks kecbackbencher I want to build a waveguide working at UHF frequency, around mhz.

Spiral antenna simulation in HFSS. Thread starter vickchen Start date Mar 26, Status Not open for further replies. Lupin Full Member level 6.The microstrip patch antenna is a popular printed resonant antenna for narrow-band microwave wireless links that require semi-hemispherical coverage.

Coplanar Waveguide Animation (HFSS)

Due to its planar configuration and ease of integration with microstrip technology, the microstrip patch antenna has been heavily studied and is often used as elements for an array. In this tutorial, a 2. The following topics are covered:. First the model of the microstrip patch antenna has to be drawn in HFSS.

Spiral antenna simulation in HFSS

It consists of rectangular substrate and the metal trace layer as shown in Fig. Note that a quarter-wave length transformer was used to match the patch to a 50 Ohm feed line. The dimensions of antenna can be found in the HFSS simulation file. Figure 1. Patch antenna layout showing substrate and patch trace. Waveport Setup In order to excite the structure an excitation source has to be chosen.

For this simulation a waveport will be used. The waveport will excite the first mode of the microstrip line quasi-TEM and then HFSS will use this field to excite the entire structure.

In order to get an accurate result, the waveport has to be defined properly; if it is too small the field will be truncated characteristic impedance will be incorrectly calculated and if it is too large a waveguide mode may appear.

Please refer to the tutorial on defining a waveport for further information. Since the substrate height is 1.

In the Analysis section of this tutorial, it will be shown that this waveport size accurately models the desired microstrip mode.

An airbox has to be defined in to model open space so that the radiation from the structure is absorbed and not reflected back. The airbox should be a quarter-wavelength long of the frequency of interest in the direction of the radiated field. Since the radiation of a patch antenna is concentrated at broadside, a rectangular box enclosing the structure is only needed; the height of the airbox is The antenna with airbox and waveport setup is shown in Fig.

Figure 2. Patch antenna layout showing airbox and waveport. Manually meshing should be performed on the airbox to get accurate results for the antenna properties such as efficiency, directivity, and radiation pattern. For this structure the initial mesh length for the airbox was set to Figure 3.

Mesh setup window. Since a Fast Sweep from 1 GHz to 5 GHz points will be chosen, the solution frequency should line within the frequency sweep range and around the passband i. In addition, the field data is saved for each frequency point in the sweep; field data needs to be saved in order to do any field post-processing.

Before running the simulation, an additional Solution Setup was added with Solve Ports Only to verify the waveport setup. This Port Only Setup was run and the resulting port mode is shown in Fig. Figure 4. Port mode showing electric-field. Plotting Results The resulting return loss of the structure is shown in Fig.

HFSS--probe in waveguide transistion

My problem is that one of the structural elements material is a mohr-coloumb material and i can't do a modal analysis for the structure because of the non linearity of this material, so I can't use the EMM or the other 3 methods to apply the base excitation at the foundation level of my structure.

Is there any updates on the EMM or any othre way that could help me to solve this problem? Is there any advice on how to apply the earthquake base excitation on a structure without using mode superposition?! You could try to do a full transient dynamic analysis with large mass method. This method uses a large point mass coupled rigidly to the mount points. Force load is applied to the mass point such that the force divided by the mass is equal to the desired acceleration.

Kind regards, Jason. Thanks so much for your response, Could you please attach an Apdl command file for any LMM dynamic analysis? There are quite a few transient dynamic analysis in the VM page. Instead of applying force at one of the response DOF, you'll apply the force F on a large mass that's say x of your total mass that represents the foundation.
