High axial ratio means linear polarization, low axial ratio means circular, but you can not tell which one is it (horizontal or vertical, RHCP or LHCP). hfss can plot all these automatically, most probably also CST, just find it out.
hi, i want to know apart from axial ratio versus frequency curve how can we predict CP behaviour from radiation pattern???i read in many papers they claim radiation pattern drawn in hfss represent CP behavior how ???plz help me in understanding it. also how to calculate front to back ratio from hfss curve (...)
how to check polarization of antenna in hfss.
Hi, Hello. I've got a problem. I need to design a antenna for cicular polarization by hfss (axial ratio Vs Freq.) My question is that am I free to choose any angle to report the antenna's circular polarization? or just at Θ=φ=0 it should be achieved? Best regards.
Create a new 'Far fields report' in hfss with the trace of axial ratio. It is one of the categories directly available after simulating in hfss. Set your Primary sweep to frequency and in the 'Families' tab, set your theta and phi to whatever value you want. A sample specification is shown
Hi how plot axial ratio against frequency with hfss? please help me
I recommend you can use a commercial software such as CST or hfss or ADS. all of them calculate the axial ratio easily and you don not need to do anything.
How to find out polarization and isolation in hfss?
If you have a licensed version of hfss, drill the application engineer for traing / demo, etc. else break your own head !
hi, I have simulated corner truncated inset fed patch antenna. It has good return loss at 2.45. Since it is corner truncated it should have circular polarisation. In papers circular polarisation is determined on the basis of axial ratio. They have the graph of axial ratio versus frequency. But in hfss for (...)
hi your antenna polarization is linear and for checking it you can check by axial ratio and polarization in hfss
check these
Anyone can tell me how to plot the magnitude of Ex in hfss? It is easy to plot magnitude of E in hfss. But I dont know how to plot Ex or Ey in hfss
Hi dlock, You can get axial ratio in hfss by using these steps 1) Right click on Result -> Create Far Fields Report -> Rectangular Plot 2) In Report:new traces window select axial ratio (Availabel in 'Category'), select function such as db,mag, or ang_rad 3) In Primary sweep select Phi, and then select (...)
what version of hfss are you running? Also, if you post your project I can take a look at it as it may be a setup error... :)
Hi folks, I wanted to calculate the phase of the S-parameter S21 of a very simple hollow waveguide between 12GHz and 18GHz as a function of the waveguide length using hfss (see attachement). Normally Phase(S21) = - (2*pi / wavelength) * length. This is obvious and it can be seen clearly in the graph between 0mm and wavelength/2 = 12.5mm (Frequen
Dear friends, I have modeled a steped septum square waveguide polarizer, which makes two linear pol to a RHCP or LFCP and vice versa. I have find all the S Parameters very good. But I need to see the axial ratio between the two orthogonal components Ex and Ey. Please explain me how can I plot the axial ratio (...)
Hi. I'm working on same thing on 10.4 GHz. Your question contains very little information. Frequency? Supplying? Model definitions?... You need define "radiation boundary" in Boundary menu and "infinite sphere" in far field in Radiation menu, than you can plot calculated axial ratios. If you want more comments, upload your hfss (...)
I was building UHF phobe exactly as the handbook says,but when I tried to create far field overlay, I couldn't find 'gain' among category of the Mag Tab. I just see those options in the blank: Variables Output Variables rE Directivity Polarization ratio axial ratio Antenna Params Design I cannot find the 'gain' (...)
Helo, could anyone tell me how to know in hfss simulation that the antenna has got a circular polarization? Thank you very much.
