You can probably excite two coaxial modes on the pins (one on each). In hfss, lumped ports should be OK.
Dear members, I am trying to simulate a conical antenna placed on a circular ground having a cut-out for the Coaxial feed. The coax contains the Outer Cylinder (PEC), the inner Teflon and the innermost feed pin cylinder (PEC). The structure can be seen below; 128776 Can someone please assist me on how to excite the
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 (...)
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 do so but receive the error of "Port 1 is assigned to an internal face". Can someone kindly assist me in assigning wave guide port to the GCPW structure in (...)
I have a homework.I have to design coplonar wave guide operating at 2 gigaHz,And dielectric constant is 3,Zo=25ohms.Please somebody help me.How can i calculate dimensions,how can i make lumped ports??Please i have to do this homework.
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 all, i recently started with hfss and needed to add a wave port however while defining the integration line for the wave port to the face parallel to yz plane , the distance along x-axis is showing zero , this causes the wave to oscillate about a point rather than travel along a
Hi, Anyone knows about how to check the angle variations in case of Frequency Selective Surface using the wave-port in hfss. Actually i want to verify the results of FSS unit cell using Floquet port and wave-port in hfss. Please guide me how the task could be done. With Best Regards: Muhammad Idrees
Trying to solve cylindrical cavity in driven modal solution type I ran into huge problems. Im not good in hfss and think that problem in feeding.
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 (...)
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 (...)
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:
hello I'm looking for an example of a design of an internal CPW in a PCB with hfss, my problem is that I calculated the dimensions of my CPW using Appcad but after simulation I don't get my impedance of 50 Ohms knowing that there is no errors in dimensions calculations help plz, I noticed that when I add perfect E boundary to my metal condu
hi i am trying to simulate slotline to microstrip transition and for that i want to use waveport for microstrip line and for double slot line but i dont know why every time i got same error msg that port ids assigned to internal face.i am attaching my hfss model also paper from which i got idea of this balun plz if anyone can guide me (...)
please send your hfss File and clarify your aim in design ??????????????????:!:
Specs: freq= 2.8Ghz wave guide dimension a=86mm b=43mm power = 15 dbm plz help me design it plzz I hav tried it like a 100 times but something always goes wrong like directivity, gain or freq. I m in real trouble my FYP submission is due next month and i m stuck with this. Please if someone has the design or someone is an expert in (...)
Hi, Iam designing a mode selector using hfss. Actually i need to characterize three modes. TE01, TE02, TE03. In that i just have to select TE03 and give it to wave guides. So, can any one suggest how to design this. I have already some theoretical calculations by which i can achieve this by a circular wave (...)
Can anybody help me by showing snapshots or procedure for giving TE11 mode in circular wave guide in hfss?
First of all hello to all of you and I wish you a happy new year I am quite, quite new in this forum and also in the topic. I need to design a cylindrical cavity in hfss. In order to start understanding hfss I decided to create some referential structures and compare the results for a case where I can analytically obtain results the sam
