There are a number of excellent books on the subject to get started with a general design. The demands that a reflector on a processor are significant so unless you have a relatively large computer and the appropriate variations on the software (FE-BI in particular) HFSS may not be the best tool. Look into TICRA as an alternate.
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 searching
Hai everyone can anyone tell me how and where we can get the mathematical equations for the antenna design.We will design a different types of antenna can we get the mathematical support for everything like length width distance between the reflector plates and the antenna for dipole the gap between the two dipoles like that???
Its a real pain to maintain parabaloidal reflector at proper proportions and at the same time providing proper flare. I have found flaring easier than and reflector cumbersome perhaps there is a cheat way to set a flare up to have a reflector (parabaloidal) reflect low frequencies despite its inadequate dimension?
Can you help me to design a Reconfigurable Frequency Selective reflector in is fed by the monopole antenna and the FSR plates are made up of copper.FSR acts as a reflector when the switch is ON and it acts as a transparent when the switch is OFF.For this i want some formulas like how to calculate impedence for the FSR and what should be the
Could you please let us know more about the Frequency Selective reflector? Is it FSS layers beneath a planar monopole antenna?
Hi All, I need to design 36" x 9" in cassegrain configuration operating in E-band (Narrow bandwidth). I know how to design regular casssegrain but in this case I'm worry about the horn/sub-reflector blockages. Is splash plate design possible for proper illumination for that fan beam? It would be great if I can remove the spa
You just design an antenna having a 120 degree azimuth beamwidth and plot its pattern the same way you plotted the unidirectional antenna. Typically these are v-pol colinear arrays with a reflector. You could use image theory to calculate point source phases and locations to obtain the azimuth array factor.
With FEKO Lite you're stuck with the 500 triangles. To do a reflector antenna you'll need the full version, or you can try GRASP. There's a student edition that's free. I personally haven't used it so I won't be able to be any help, but a colleague of mine speaks highly
Hello I designed a simple corner reflector with HFSS and I set terminal impedance to 75 ohm.Here is my Hfss output S11 and input impedance of my antenna. 126392 (So at F=8 Gighz we have S11=Gama=10^(-10.7358/20)=.2905 126393 (as you see at the F=8Ghz image part is approximately around 0 and so w
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 the parabola in the far
Good Morning, I am facing an issue. I have modeled a coaxial cable and modeled as well one rectangular mirror or reflector inside the cable such that we can see dips in S(1.1) vs Freq. but the problem is after having first dip at 13 GHz, then the graph is distorting heavily and looks more like noise. Can anyone say what possibly could be done to
What would be more correct for calculations: 1) connecting two antennas centers with point reflector using non-parallel lines or 2) connecting two antenna centers with point reflector Z-position using parallel lines (so the second line does not ends exactly on point reflector, but altered in Y-direction by antenna distance) or 3) (...)
In the project manager look for the reflector antenna icon ...... make sure you have set up a far field sphere to calculate radiation patterns in the first place. that plus the information above.

Use several good Toshiba or Cree 1W or 3W LED and heatsink then drive with Thermistor to regulate Logic level <=50mOhm Nch MOSFET with drain to cathode LED and epoxy thermistor to heatsink for 50'C to adjust 1V gate voltage from 3.7V LiPo. If you dont know how to design an LED heatsink, buy one with heatsink and reflector. LED should be 2.85V @
I concur with Bigdogguru. Depending on where it is fitted, and whether you can live with it being slightly directional (more than it already is), you might be able to use it as the active element in a short Yagi antenna. In other words, fit a reflector behind it and one or more director elements in front of it. Something along the lines of a TV ant
Hi I want simulation the cassegrain reflector antenna with feko. when i run ke simulation i have this problem,ERROR 36728: Internal FEKO error. Please notify the FEKO support team and provide the error number, preferably together with the FEKO input and output files. please help me how can i solve it?
I want simulation a cassegrain reflector antenna with feko and get radiation pattern of it.
I mean to say how to assign excitation in a zone plate... - - - Updated - - - I want to simulate the plate as a reflector (by placing horn in front of plate) as well as a lens (by placing horn behind the plate). I want to know the steps for assigning boundaries and excitation for the plate part and then sim
