You can probably excite two coaxial modes on the pins (one on each). In hfss, lumped ports should be OK.

Hi, I am using hfss-13 and could not find some detailed help how to used this software. I have got manual for hfss-10 but there are some differences which are not addressed in that (being manual of old version). Can anyone guide me to manual/help of hfss-13 which can prove fruitful for learning this software. Thanks.
Hy every one. I am new in LTCC. I have designed Patch antenna in hfss before using Rogers substrate 1.5mm thick. Now I want to design it with LTCC material. But I don't know how to choose LTCC substrate and how to design such antenna in hfss :-? . Anyone please help me. A step by step procedure will be helpful for me. Thank you
Hi, is there a way for hfss to directly plot mixed-mode s-parameters? If not, does anyone have a good guide, or equation, for a generalized conversion between single ended and mixed mode results? I'm currently simulating an 8-port network, so equations from 4-port network conversion (which are everywhere on the internet) are not so useful. Any h
Hi Guys, According to the Ansys Help guide, the Create Array Command (in the context menu of model in the project tree) is automatically enabled when Master and Slave boundaries are assigned. Well I have assigned master and slave boundaries to my unit cell and the command is still disabled. Kindly help me out. I would like to create 1D array as sh
Hi all, I just started working on on-chip antenna design. Mostly CST and hfss are used for on chip antenna design, can any one please guide me which tool is better for integrated antenna design on CMOS. I also want to know if anyone knows about how can I get my design fabricated. As we do not have the facility in our lab. Thanks, Deep
Dear members, I am trying to simulate a conical antenna placed on a circular ground having a cut-out for the Coaxial feed.

hi i am designing a wave guide whose side walls are sinusoidal corrugated. the corrugation of the walls depend on several parameter parameter, one is called delta which supposed to be very small. i design a matlab code that generate the same result of hfss but only for small values of delta, and an upper bound on value of delta need to be known b
Hi Members I am trying to excite a simple patch antenna using Grounded Co-Planar Wave guide Structure (GCPW) by the techniques shown below in Fig.1.

i m doing a project based on microstrip patch antenna . can someone provide me with microstrip patch antenna simulation file of hfss using triangular wave guide?
Hello neffi, Select the circular face at the tip of the coax and assign a waveport, the integration line should be from the center core to the metallic shield. For more information look in this user there's an example about probe feed antenna
It seems you want to feed a simple wave-guide. If so, why do you define an integration line? hfss considers wave-port as an infinite wave-guide which automatically feed correctly, I mean with correct polarization and the dominant mode. In lump port definition you have to define an integration line.

It is available in the hfss scripting guide. You could find it from the Help menu or just search the doc folder under the installation directory. Hey thanks, worked like a charm. If you don't mind me asking, where did you find that information? Or was it trial and error?
Hello! I'm working on a project: There is a titanium bar in the salt water, and an E field along the bar with 100 V/m at 64 MHz. It should be a wave guide. I set up the model and assigned the material, but I don't know how to assign the E field and plot it. Attached is my hfss doc. Could anyone help me on this or teach me how to assign the field?
Hi I have a simple rectangular wave guide filled by air. I want to apply PML for boundaries in x and y direction and electric wall for z direction boundaries. and then take the S21 of of the structure which should be 1 since wave guide filled by air. There are some tutorials on how assign PML in hfss but they are applying plane wave (...)
For assigning a PML boundary to any surface in hfss: select the face,right click and select assign boundaries: you should select PML setup wizard, in the PML setup : change the minimum frequency for your design. Make sure the Master/Slave boundaries include the PML. That's all. Generally, for designing FSSs is hfss, you can go with three options:

Hi, I'm designing a coplanar waveguide spiral inductor in hfss. I draw the waveport with dimensions: Width = 3(2g + w), where g is the gap size between the ground and the conductor and w is the width of the conductor, and length of 4*g as said on the hfss guide. I drew rectangles of these dimensions and assigned waveport (...)
CPW is very hard to setup in hfss I would recommend going in using a coax or microstrip and transitioning. However, it looks like you don't have a large enough airbox around your system to show the correct radiation pattern. you need a minimum of 1/4 wavelength at your lowest frequency from the edge of your antenna in all directions. I usually
