I did not used hfss, but I guess there must be examples for such antennas. You can start by altering examples, and make them from scratch to remember typical steps. For example, Sonnet lite have example of coaxial fed patch antenna.
HI, i have designed an cavity backed antenna in driven terminal using two co-axial coaxial feed length is 40mm..if i assingned air as material to the cavity i can run the simulation without the error and my return loss value is less than -10db.if i am assigning copper as material to the cavity i am getting very low return loss.what mat
Hi, I am trying to simulate a coax connector in hfss and trying to correlate simulation results with theoretical formulae. Currently, I have modeled a coax connector with a GOLD inner conductor and PTFE dielectric(epsilon = 2.1). I have setup ports at both ends of the coax with port impedances 50 and 80 ohms respectively. As per theoretical
How can I draw magnetron vanes in hfss? If I simulate a magnetron whit 2 coaxial cylinders,then how can I simulate the magnetic field applied to the cylinders? (in magnetron we have a magnetic field crossed with produced electric field(or electric current from cathode to anode) tnx alot
Hi, I tried the simulation with hfss 13 and 15, and I got similar results in terms of matching and radiation patterns. My only concern is that you use an air-dielectric coaxial, or you forgot to assign material (e.g. Teflon) to the air in the coaxial probe. Regards, Pere
gd morning please , I need someone to explain to me how we define the port in hfss and the boundary and what are the rule of " asign perfect E ..." Many thanks
Hi all, Could anyone tell me shall I normalize the waveport impedance to 50 Ohm when simulating a waveguide structure in hfss? And why? Thanks in advance.
You can find a good details about coaxial feed simulation in hfss by visiting this link good luck
Hi. I has designed a microstrip patch antenna array in hfss.It's feed is an coaxial SMA.But in simulation the wave is not going throw the array.The inner in coax is tangent with the array and it's shield is tangent with the ground plate
Yes. the Port looks good. I do a simulation from your project and it works. But you should do some work on it, because your "air" is not very well placed. It should be lambda/4 away from all edges of the antenna. And i don't understand the sheet "Rectangle1". The resonance frequencies in my solution are 820 and 1095 MHz. @mohamed.hagag i use both
I am a new user on hfss. And I am creating a coaxial probe. The simulation result in S11 does not show properly. Can anybody help me to have a look my hfss file? Thank you. 86358
Hello Everyone The Problem i have here is more of a drawing problem in hfss and not the simulation.I have a co-axial cable that is being used as an element of a bifilar helix,after drawing the helix,from the tip of helix the coaxial cable is to be drawn at 90 degrees from the tip.does anyone have any idea how to do this.i have drawn the (...)
hi.. need to feed an annular slot of avg. radius 7.7mm and thickness 1mm..need to do the simulation in hfss..tried alot..din work yet..wil be thankful if u cud help..
Hello I'm a newbie to hfss and I'm trying to design an inset fed patch antenna design using hfss. Does anyone have any steps (not coaxial patch antenna) of the inset fed patch antenna design using hfss? I'm trying to run this simulation for my school project! Any help is greatly appreciated. Thanks,
hello; im going to design a printed antenna withcoaxial feeding resonants at 3 and 5.5 GHz at the same time. i modelled this antenna with cst and hfss respectively. simulation results are fitting. so i fabricate this antenna and get the measurement results. but there are differences between simulation and measurement. i (...)
Hello to everybody, does someone know how to define outer conductor of a coaxcable in hfss 10? I simulate patch antenna with coaxial excitation, probe = pec and dielectricum = teflon and it still works, but what about the coax outer conductor in my simulation. It's not necessery to define? greetings armant
Dear forum I am designing a planar microstrip UWB antenna using a fractal geometry. I am working on hfss. I dont know how to connect the port to my design. Should i use a lump or a wave port. I used a lumped port by creating a rectangular patch between the printed side and additional ground (on reverse of substrate) and then assigned it as lump
Hello everyone, I am trying to simulate a 3x3 antenna array in hfss. I am only concerned about the response of the center element, and thus only need 1 wave port. All of the stacked patch antenna elements are fed with a bottom-fed coax probe. Is there a way to ensure a 50 ohm termination on a coaxial probe without inserting a wave port? I wa
hi there i am new to hfss although with what i know about hfss i tried to get the result of a structure given in a research paper. its related to simulation of two patch antenna with and without slot in ground plane. i tried many days but i couldn't produce the same result as given in the paper. i am posting the paper details and my (...)
For the purpose of training and education, I am looking for an example of using hfss to visualize the effect of an antenna connected directly to a coaxial cable. How to visualize the external current in the coaxial and see the difference when connected to a BALUN. Anyone has a model like this?...Or any ideas?
