Hi everyone. I am trying to simulate a non planar helix coil in Ansys Maxwell but the simulations can't go past the initial meshing step. I posted about this problem at the end in one of my earlier related post but I couldn't find the reason anywhere. Simulating planar coils for Wireless Power Transfer is working out just fine. But these (...)
Hi all I designed a planar antenna that would be a unit cell for a 4×4 phased array. My PC resources are limited and I want to know what configuration i may use in order to speed out simulation and optimization of the array's parameters.
Hallo every one, I am a beginer to hfss as well as antennas , I have chosen my area of research as metamaterial based planar antenna for which ,i have collected many papers , i have gone through them . My need is if any one can help me in giving tutorial for simulation of such it is very urgent.Thank you in advance.if. any one can su
Hi everyone I am simulating a Log-periodic antenna in hfss. In the beginning I had got the planar version with surfaces only, it takes about 10 mins to be done :wink:. Then I tried to do the wired version simulating only the periferial shape making the path with very thin cylinders joined. Unfortunately latter simulation took almost 2 (...)
Welcome DhruvJadeJa, You want to use an Eigenmode simulation, be sure to understand Bloch's theorem and periodic boundary conditions before you proceed. I've previously written up a summary (for planar structures) at Good Luck
I can confirm that in hfss for eigenmode simulation of planar structures, having the PML 1/4 of a wavelength from the structure gives the same results (or as much as is discernible) as having it to within 1/30 of a wavelength. As far as I can tell from the information provided, your setup looks correct.
Obviously, you cannot simulate/mesh to numerical infinity. The infinite substrate in planar tools means that the substrate is homogeneous throughout the simulation area. In my opinion, in hfss and other volume meshing solvers this means that the substrate is homogeneous up to the boundary conditions.
All this software is somehow useful for planar filter design, if you know the filter design methodology. hfss, Sonnet and CST can do EM simulation to analyze the layout when it is ready. ADS and AWR can do both: fast circuit model simulation to develop the initial layout, and also EM simulation to analyze (...)
For a faster, less accurate solution, you would transition to 2.5D planar solvers that utilize some sort of Method of Moment technique. The planar MoM solvers are not less accurate. They solve the full Maxwell's equations, using a method that is optimized for planar structures.
hi for simulation in hfss and design of antipodal u have some way draw by tool or give the equation to hfss for more information about antipodal u can read chapter 5 of Broadband planar Antennas Design and Applications by Zhi Ning Chen and Michael Y. W. Chia and u can download a thesis by topic of UWB-Antennas for Wall (...)
Dear all, I would like to simulate coupled coil, for example 3D solenoids or planar inductors. As the received power depends on numerous parameters (number of turns, distance, symmetry, frequency, permeability, even unconsidering non-linear phenomenoms), so magnetic field produced and received, simulation seems useful. Do you recommend som
I'm new to hfss. For simulating planar dipole RFID antenna using hfss, I noticed that lumped port is used usually, and the lumped port impedance is set to the conjugate value of the chip impedance. My question is: Because RFID antenna is directly connected to the tag chip for cost down, then the impedance of the antenna should be (...)
Hi, I need examples of PIFA in simulation software.(hfss.IE3D,ADS,.etc) please attach related files in this post. Best Regards, Ehsan
This report aims to find a proper simulation setup of hfss for single-turn small loop antennas, with a comparison with calculation. Temporarily only the square planar type is studied, which falls into the popular group of printed antenna. Any comment is welcome.
What kind of antennas are you talking about, planar, helical or ..? I personally prefer hfss, but it is very expensive. :D
I have this book....if you need it let me know; "planar antennas for wireless application"
I have a planar log-periodic in both.
Hallo, we defined two lumped ports to excite a differential planar inductor, which is symmetric. Is it possible to delete half of the structure (even the second port) and just calculate one port ? greets elektr0 Added after 5 hours 10 minutes: The second question is, if there is only one port with cal
It is better to use 2.5D simulator for planar circuits with consideration on the accuracy and simulation time.
1. import ADS layout (GDSII) into hfss for simulation. 2. import ADS layout(GDSII) into ansoft designer as planar EM component, import hfss component int odesigner as dynamic link 3D component. Do simulation in designer.
For planar structures, ADS is closer if you have set sufficiently meshing density and edge meshing. this has been proven in many times by developers and designers. ADS2005A gives the best simulated value for such planar structures.
ansoft and ads are for planar couplers, there are also IE3D Microwave Studio, and FEKO, but I am not sure which will give you the most accurate results
Hi Jslee -- If you are using the volume meshing part of hfss, switch to the planar solver (it meshes only the surface of the metal of your microstrip line). I would think that the hfss planar solver should have no problem with a microstrip line, including using their interpolation, but I have no actual user information on (...)
Designer or hfss can be used to simulate planar antenna.
you can simulate quasi yagi antenna in CST but you can't do it in Sonnet since it is 3D planar. CST and hfss are 3D arbitrary structure EM simulators. regards, Lkuzu
Hi, I wanna simmulate a planar inductor. Normally planar inductors are made of several metal layers conected together by vias. The inductance value is quite easy to estimate, but Q isn't. I wanna know if there is any sofware (Ansoft hfss, for instance) that accurately simulates the substrate leaks, so giving a good approximation of (...)
