## help for my project in hfss

## Angle of peak gain in HFSS?

Folks, I'd like to be able to pull out the peak gain along a specific phi cut. That is, along a \phi_0, I'd like the \theta corresponding to the maximum gain. Any ideas on how to do that aside from plotting a rectangular plot of the E_{total} along \phi_0, loading that into MATLAB, and doing this? T

## HFSS Antenna Array Simulation Result (Wrong :S)

i have created an array with 4 elements. The pattern in matlab is great. 127214 i designed same array on hfss, the result is awful but it looks similar. There are some symmetry problems along y axis. Radiation pattern on phi plane (at theta=90) is not same as matlab. i must figure it out What can be the problem? ple

First go to Radiation in Project Manager. Right click, insert far field setup, Infinite sphere, set theta and phi as start:0, Stop:360. Step Size:1. Now right click on Results, Create Far Field Report, 3D Polar Plot, select trace tab, Category = Gain, Quantity = gain total, Function = none. Then click New Report. WAHLA!!! ;-)

## How to relate Horizontal and vertical polarization with Phi and Theta

From searching and brainstorming I came up with Vertical polarization = theta polarization Horizontal polarization = phi Polarization (Correct me if I'm wrong) In my design my antenna is facing in X direction like in the picture 117293 I am using hfss. For getting the vertical and horizontal polarization I am defin

Angle of phi what will change? does it change the polarization angles? Angle of theta what will change?does it change the incident angles? If number of modes in floquet port be 1 what happens? For define in the design, TEM mode what i should do?

## how can i change the angle (theta and phi) of incident wave in waveguide in HFSS?

Hi, everyone I am now using hfss version 13 to calculate S11 and S21 of a metamaterial absorber. wave ports and PEC/PMC B.C. are set up in the simulation. For the wave port, the plane wave incident angle is zero in default, but I want to use an oblique incidence(for example theta or phi=10 deg). What should I do to realize oblique (...)

## HFSS Monostatic / Normal Bistatic RCS

Help please! I am simulating radar cross sections in hfss but I am a bit confused. It seems in theory that monostatic RCS and Bistatic RCS at theta=0, phi=0 with the same excitation should be the same. When for example, I simulate a 1 cm radius conducting sphere at 10 GHz I get -34.25 dB for Monostatic and -27.76 dB for bistatic at (...)

## Plotting E and H field in HFSS (2D Radiation pattern)

Hi vijaimvk, I'm not sure what you're trying to do. You can plot 2D plots by selecting Far Fields Report -> Radiation Pattern. You can then plot vs theta or phi, selecting the cut angles with the "families" tab. Good Luck

## how to check scane angle in HFSS for floquet port ?

Hi to all; I am using the floquet-port with master-slave boundaries but the confusion that i am facing is how to check angle of incident wave at the floquet port.

## fractal antenna design for UWB spectrum

## Antenna radiation pattern in hfss

First off all, no need to change the default infinite sphere settings. Plot a full 3D pattern so you know what to expect from 2D patterns. May be you get the same plot because the pattern is symmetrical. To plot a single plane choose a phi value and sweep the theta values. The H and E planes will depend on how you placed the antenna in your simul

## Help with phi and theta sweeps in HFSS

Hello, i need to change the range of the sweeps. Make theta range 0 to 180 instead of -180 to 180 and phi 0 to 360 instead of 0 to 180. I know its the same calculation but it matters to me for the exported data. Anybody know how i can do this? Thank you a lot! - - - Updated - - - the answer is to set u

## problem in HFSS (axial ratio)

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

## how to understand the gainphi and gaintheta of hfss

Make sure you clearly understand what the spherical theta and phi directions are. Remember that the theta always points along the elevation direction and phi is in the azimuth from X axis. They are not like X, Y, Z vectors which always point in fixed directions. Personally, I would advise following the Ludwig3 convention as (...)

## gain vs frequency 2d plot in hfss

I'L take u have done a frequency sweep simulation for ur structure..!! Since u said Gain, I'L take it is an antenna u r trying to simulate ..!! Have u defined an Infinite sphere before u plot ?? If not do it, den u need to fix theta and select all phi, or fix a phi and select all theta according to the requirement of ur plot (...)

## Metamaterial unit cell simulation with Floquet Port and periodic boundary condition

Hi sc4rppph, As a disclaimer, I don't use Floquet ports, but the setup looks correct to me as far as I know (hfss 13). For the master/slave boundaries, you probably just want to use the specified phase angle rather than theta/phi for square structures. To get the dispersion diagram, set the phase angle of Slave X to a variable AngleX and (...)

Some of my colleagues had done some designs of FSS in hfss. I think the theta and phi are to define the angle of incidence wave. The response of FSS would be different with different incidence angle.

## HFSS Gain Toal & Gain Theta

Hi, At hfss Results - What is the difference between Gain Total at phi=90deg to Gain theta at phi=90deg and Gain phi at phi=90deg ? And at 3D Polar Plot - What is the difference between rE to Gain Total ? it is look that only the Gain Total is useful .

## confusion in calculating gain in HFSS

The peak gain is the maximum gain of your antenna. And the total gain is the gain in the given direction. Your results indicate that theta=360 and phi=0 isn't the direction of your maximum gain. You can plot a 3d diagram for one frequency and check the gain figure for the direction of the maximum gain.

## what should be the value of theta and phi for plotting the gain v/s frequency in hfss

Vishal There is no such fixed value that can be taken, Because with change in frequency the pattern on most antenna changes so does the max gain with direction with changing frequnecy. so my advice would be do it two ways 1. gain in the intended direction, for instance you want to your beam to face a certain direction with your max gain at theta=0

## HFSS 13 Radiation Efficiency Well over 100%

Calm down. As the others wrote, it must be something trivial. Why don't you check your integration area (sweep range for theta and phi) for the radiated field? It's very likely that you sampled the same angles multiple times.
