i am planning to design a VSAT antenna.... i managed to make a horn antenna....now just need to add a reflector in front of this....Please can anyone describe me the geometry of Paraboic shape in CST? or what kind of extrude curve i have to use....this must be a great help for my personal projects. only the physical reflector design i am (...)

hi antenna experts.
i designed a Reflectarray unit cell with proper phase shift in CST.
i used unit cells in array and fed it by a horn antenna.
the solution type is integral equation.
now i want to know how can i gain the phase of each element(phase of fields or reflection phase ) after feeding by horn.

I'm working on Reflectarray.
i have designed my unit cell by CST.
after designing the unit cell i placed the cells in array form and excite it with a horn antenna.
now, each element have it's own phase in re radiating field. so we should know the element phases to compensate them to make all elements radiate in phase, but we could no

What I remember is, wave guide also plays important role in this design ( including ridge thickness & height).
Distance of probe from bottom,impedance plays crucial role.
Remember one thing, you are transferring impedance from 377 ohm to say 50 ohm.
so this transition should happen smoothly. Curvature of ridge is extremely important.
What I recom

I have a horn antenna working at 144GHz with A=12mm and B=14mm. Then I'll illuminate a satellite dish of 57cm diameter with this antenna, with the feed located at the focal point of the parabola. I have the radiation pattern of the horn, made with MATLAB.
The goal is to know the beam propagation (power radiation) pattern of (...)

Any one help me to design Fresnel zone plate antenna in HFSS. The design has two elements. (1) A plate having circular rings of different radii. It can be made by printed technology on RT/duroid 5880. and (2) horn antenna as a feed. My doubt is how can I simulate this complete design (plate+horn)?
how to simulate t

i am beginner in the use of HFSS. I design pyramidal horn antenna, validate is ok.but error after change material to aluminium.
Port refinement, process hf3d error: Port 1 does not have a solved inside material on either side..
Simulation completed with execution error on server: Local Machine.

I am working on a h plane horn antenna.
First I calculate all dimensions that it needs, then I simulate it in the CST but my results are strange.
I have a good gain about 6 dB that it is fine in this level
I do not have any loss when I am checking the E-Fields
But my s11 is awful, it is almost zero, working like a resonator.

does anyone know about pillbox antenna for LMDS? now am doing a project about sector horn,but some
happened.the questions as follows:
first,how to design the aperture to meet the azimuth power pattern?now gain and HPBW are very well,but the power pattern is not suitable for ETSI.
second,the peak of elevation power pattern is startin

Hi every one,
I am simulating a horn antenna with a wave port with two orthogonal modes (to get circular polarization), the combine option in Post processing tab is not available for me. it gives me this warning:At least one propagating mode is not considered at port 1.
Can anyone help me please?
Thank you very much

Please can someone guide me how to assign the port for the offset feed horn?
For the focus feed horn, we have the aligned feeding towards our antenna but if we need to make it offset, we need to tilt it so it makes the feeding no longer align with the antenna.
So my friend told me to use coaxial probe and assign (...)

I created a corrugated horn antenna model and I was trying to validate it but there is an error message "non manifold edges found for corrugated". I have tried to fix this issue using the solutions available in previous threads but its not working.
Please help me! Thank you very much!
Model file is attached.

I have designed a horn antenna for Bluetooth application and for simulation purpose I just want to make one with curved end. I have tried to do it by intersecting with circle, but the problem is when I changed the length of the horn antenna the shape of the curve is changed too and becomes flat.
In case it (...)

Hi, I have radiation pattern results from anechoic chamber which I need to plot. The data which I have are the XY, XZ and the YZ plan each with co and cross pol data. I did the necessary calculation using the horn antenna(source) gain values.
Now, how do I calculate the total E field gain? Example, in XY co pol at 5GHz, I have 360 values since t

If I understand you correctly, you are trying to model a realistic version of a horn antenna that could be 3D printed. You could model the horn with ABS material, for example, and then pick the internal faces and create shape from picked face and model that as gold material.
However, you might also have to extrude this new shape to (...)

I'm simulating a grounded CPW in CST,
I want to apply a proper boundary condition to it?
who know what is the suitable boundary condition?
what envirement i shoud use in CST?
note that i'm simulating a GCPW fed horn antenna if this effect the boundary condition of structure...
